It is not really circular if you need large amounts of energy to create CaO. The lower temperatures do suggest it might not be as bad as Cement, but how endothermic is this reaction? Also, in the curing phase, where does the Ca(OH)2 get its CO2 from? If it is purely atmospheric CO2, then how does the CO2 penetrate to the inside? What are the limitations on thickness? Lastly Ca(OH)2 is difficult to handle. How does one avoid chemical burns on yourself and objects? Additionally, what did you need to use cement for? Why?
Hello, all very good questions. Yes it does take energy to create CaO but as you rightly mentioned, the energy consumption is lower than cement. Also because the finished product is Ca CO3, it is circular. The CO2 is purely atmospheric. It penetrates thin layers easily. But for a thicker layer, we use pozzalon materials, which builds more air pockets in the mortar/ plaster, allowing air to circulate and for the lime plaster to set faster. Working with lime is a lengthy process purely because you need to give time for layers to react with air and set. The material is usually handled with a spade. We didnt see any instance of burns. Of course, you can always wear safety gloves. We had to use cement wherever we made a beam or a pillar with rebars. This is because steel reacts adversely with Lime.
Really loved the way you and Malvika have deconstructed the idea of why lime is more sustainable. Simple and profound. Best wishes and keep sharing such stuff. Thank you.
Thank you Manisha for this educative video. I am building my Farm Land in Karjat, Taluka, Maharashtra. I am using, a combination of Basaltic Rock, available in my area + Soil+ Lime to build my boundary wall. Iam convinced, I want a sustainable House, so its gonna be rammed Earth.
Hi Manisha I have been following you from Africa and love your inspiring videos have got a beautiful peace of land and would love to build a home with natural materials their are so abundant here
I want to build my home with basalt (no metal) some low fired bricks and I thought “aircrete/ concrete “ but now I realize i should use lime instead. I hope there are ways to do this, thank you!
in the history of millions of years.............Lime might have never thought of this........that some day sophisticated ladies would be discussing about him
The longevity is undoubtable but please also speak in price expectations (per sqft for initial build) for the affordable housing crisis and not just the sustainability crisis.
Great explanation! Thanks for making this video. I have 2 questions: 1) Is lime waterproof? Can it be used for external walls that are exposed to the elements? 2) Could we use lime to build a water tank? If not, what would be the best sustainable material for this job?
You can definitely make a water tank in lime. But you will have to wait for about a year before you can start to use it as it will take that much time to set completely
thanks for the information. If lime and sand mortar is prepared for brick laying what is the curing cycle ? How many hours after construction should the curing start and for how long ?
Hello! We have an old house that in which the brickwork and plaster was done with lime+ some other materials. Now that walls are strong but in rainy season, the water seeps through the walls. So when building a new house, how to use lime to make it stronger against elements? Can we mix lime with normal cement for brickwork and plaster? And, how to do lime putty?
You should consult a local artisan about how to make lime plaster and brickwork waterproof. There must be cracks in the old mortar that are allowing water to seep through.
Natural Moisture Regulation: Unlike cement, lime has the ability to absorb and release moisture, helping to regulate indoor humidity levels. Cement tends to be more impermeable, which can lead to moisture buildup and potential issues with mold and mildew growth. Improved Indoor Air Quality: Lime-based materials are breathable, allowing for better air circulation and exchange. Cement, being less permeable, may trap indoor air pollutants and allergens, potentially leading to poorer indoor air quality. Non-Toxic and Eco-Friendly: While both lime and cement are natural materials, lime is typically considered safer and more eco-friendly due to its lower environmental impact during production and its non-toxic properties. Cement production, on the other hand, can involve the emission of carbon dioxide and other pollutants. Thermal Comfort: Lime-based materials offer natural insulation properties, helping to regulate indoor temperatures and reduce the need for artificial heating or cooling. Cement, while providing structural stability, may not offer the same level of thermal comfort due to its lower insulating properties. Antibacterial Properties: Lime has inherent antimicrobial properties, which can help inhibit the growth of bacteria and other microorganisms on surfaces. Cement does not possess the same antibacterial properties, which may make lime-based materials more suitable for areas where cleanliness and hygiene are important. These factors highlight some of the unique health benefits associated with lime-based materials compared to cement.
This contains useful information and errors. Whenever the lady says cement, I assume she means Portland cement. Lime can also be used to produce cement . Portland cement is about 65% lime. Portland doesn't get weaker after day 28. That's the preferred cure time before you put weight on a slab or put a lot of weight on pillars. About 35 years is generally considered when Portland cement has reached its maximum strength, in dry conditions. I intend to use self-produced calcium hydroxide samantha, also known as slaked lime, for the majority of my building, since my place is on limestone and we have a very tall persistent grass, which can be used the fire the kiln. I will use mostly Portland cement additional pozzolanic materials for footings and pillars. I expect that the majority of our infill will be a mixture of rice husk and coconut coir, with lime binder. We will probably use a wattle and daub framework. I will watch other videos in this series and I'm sure there's something to be learned.
Thank you for sharing your feedback and knowledge. Yes 'cement' is portland cement. Your project sounds wonderful. I hope you do plan to document it and share this experience with others. All the best!
Two questions: Is it not true that cement also hardens with exposure to CO2? Is it not true that Natural Hydraulic Lime, NHL, hardens initially with water, like cement?
Hello mam, i have a question, I want to start a hotel using such a construction, do you think it would be safe, also will it be cooler without the use of air conditioning, please share your feedback, also whom should I contact if i do want to go ahead with this project?
@@farmaanandaa limestone is softer material and is not much durable, compared to cement it can erode very easily over time. I think you guys being professional must be knowing it, so my question is what you guys do it to prevent that?
@@_.-._SHAAN_.-._ lime mortar and plaster/render is softer and not as strong as cement, but that is misleading. It is actually because cement is stronger meaning more rigid that it cracks when there is slight movement in the building, especially so for old buildings. Your mortar and plaster render should always be softer than the bricks or material it is binding to. This preserves bricks and other materials as cement is too rigid so when it moves it breaks or cracks the bricks. Stonger is not always better. Lime is more durable in the sense that it is breathable and flexible giving much greater longevity than cement. Think about all the ancient buildings around the world that were built with lime. Now look at the modern concrete buildings, floors and driveways. The concrete ones all crack very soon after being made. They cannot stand for hundreds or thousands of years. However many were mixed with natural pozzolans (fly ash, volcanic ash, GGBS, Metakaolin clay, Silica fume, red brick dust, rice hull ash, wheat straw ash, etc) which produce a stronger lime if it is needed for heavy structural support. There is a lot of info about it online which can articulate it better than I can. I hope this helps.
@@farmaanandaa which form of lime you used for rammed earth. I doubt it was quick lime made to slaked lime as rammed earth mixtures would have little moisture in it and slaked lime would be difficult to mix in it? Or you used slaked dried lime (which we call hydrated lime powder).
Excellent presentation! I hope you can clear up a point of confusion for me. I'm living on the east coast of the US . I can go to the construction material store and pick up a bag of hydrated lime ( ready to use lime binder). Is that not something you can do in your location? Or is there a quality issue with what is available?
Construction quality hydrated lime is not easily or commonly available in India at a store. In fact that is exactly what Malvika and her company MLIME are solving for! They are now selling packaged Fat Lime, ready to use for construction.
One very important aspect is not informed in this video. Lime reaction in construction is indothermic , whereas cement reactions are exothermic. Also Lime reactions in construction generates Oxygen & cement reactions generates Carbon dioxide.
@@farmaanandaa Hi, could you please help me where you shopped lime or any online link would be help. I am a new bee and want to try out myself with sample walls. Thankyou!!
Did you heat lime stone at 800 degree. To make quick lime. Then you add water to slaked it ? ( Or Just we purchased Lime in shape of stone from market and add water ? )
It depends upon the materials and environment as to which is best. Contact local experts before moving ahead. Choosing the wrong materials can be an expensive mistake.
Because we all now use cement and almost no lime, I presumed cement is a lot stronger and more durable. Why are skyscrapers not built with lime instead of cement concrete?
As a structural engineer. , I am not fully agree that concrete strength especially compressive strength will be weakned by day 29. This is not correct at all. Concrete will still.gaining its compressive strength up to 1 year or more, but the rate of increase will be a bit smaller than the first 28 days.
if your contnt might more effective if it would be in Hindi, it might possibel that you only target urben clients but more and more people could use this in villages. so translate in hindi as well.
Lime breaks down very fast compared to Portland cement. While this may appeal to people who think about it decomposing, I want what I make with it to last longer than me. Lime lasts a few years or a decade. Portland cement lasts many decades.
Cement with aggregates that was referred by the younger lady is called concrete, who ends it by saying it's strongest at 28days and has a life of 30yrs 😮😂 A little bit science is a good thing 🤭🤭🤭
@@farmaanandaa fyi there are people you know personally who know the science I know, but that said: - a concrete wall will easily last 100+ yrs. - an RCC building foundation or cast will last a 1000yrs. - concrete erodes very slowly and is easily protected - unlike in the video if it's just on the surface that you want to repair as in plaster it is easy to replaster - concrete can last 2000yrs or more like made with volcanic ash as the Romans did because of the creation of aluminium tobermorite. Limestone is great for sustainability etc but let's not confuse the issue. For more science feel free to ping me 🫡

It depends on the quality of your soil. There is no standard formula.

Lime is just a binder like cement. You can use it to make anything! All old multistorey havelis in Rajasthan are made of lime
It depends upon the materials and environment as to which is best. Contact local experts before moving ahead. Choosing the wrong materials can be an expensive mistake.
Sure

A few days.
What do you use for the foundation?
Stone and lime mortar
Because we all now use cement and almost no lime, I presumed cement is a lot stronger and more durable.
Why are skyscrapers not built with lime instead of cement concrete?
Cement is quicker to set, so you can build one floor above the other quickly. It does not last as long as lime does.
