Very good information for college students taking engineer math I'm more of a one bag cement to so many shovels sand so many shovels aggregate or buckets 👍
All aggregates were multiplied by 0.28m3. Am I correct to say Quantity of cement = ration(1) x 0.28 =0.28m3, Since you multiplied sand(1.5) and stone(3) by 0.28?
What is the proportion of aggregates 0.2, cement and sand for plastering purposes, to be used in plastering pumps equipments. Thank you to advise on same.
I understand the one, two, three mixture. depending on the size of aggragate the three is subject to be more or less. I mean one using 3/8th vs 3/4 would need twice the amount, thus the three would be six. The process of doing an exposed aggragate of 3//8th is considerably slower process than using a total mixture of one, two, six. In either case make sure the aggragate has been cleaned until the water runs clear.
In my opinion, the calculation is wrong. The volumetric ratio 1: 1.5: 3 is at the dry stage. when added with water the voids in sand and aggregates get filled with water . The volume of resulting wet concrete mixture will be 1 + (1.5 x 1.2) + (3 x 1.34) = 6.82 Cumt for the dry 1 + 1.5 + 3 = 5.5 Cumt volume of the dry mixture. Thus 1 cumt of wet concrete will contain (1/6.82)= 0.147 Cumt of cement, 0.220 Cumt of Sand and 0.807 Cumt of aggregate. Thus for 1.54Cumt of wet concrete, it will be 0.226, 0.339 & 0.678 respectively. For your review please.
You are right, but void is filled with water, difference between wet and dry concrete is volume of water. It is already considered as negligible for costing.
My mason used one part cement, one part stone chips and one part sand to make a small lintel . Is there any mistake ? Will the concrete crack ? Sir please reply .
So, for about 1cum (?!) 8 bags of cement, 12 bags of sand, and 24 bags of aggregate assuming the bags are the same size and the concrete bags are 50kg.
Because everything is a ratio of cement as the binder. Even water is a ratio of the cement. By the way, best practice is using weight as opposed to volume, but it tends to be cumbersome on a job site so vol is used as a rough substitute.
My house has tin. We want to change it into a roof made of cement but we don't know the materials required and process of how to do to. We have labourers but no superviser. Can anyone help?
When concrete is mixed, it undergoes a reduction in volume due to factors like the inclusion of water, which is necessary for the mixing process. The 54% addition could account for this volume change, converting the dry volume to the expected wet volume after the concrete mix is prepared. This adjustment ensures that the calculated rate covers the actual amount of concrete needed for a project, accounting for the increase in volume during the mixing process.
@@engineeringmotive6669 thanks for the reply I understand the 54% I just don't know what the 1 + 1 bit is I get your working out for 1m3 just don't understand 1 + 1
Sir for your video rate analysis of mason considered 0.1 % = 100rupess,but helpers you have given 2%=1200 rupes.may be it was wrong I think it's 120 rupess then prize may vary
Doesn't the percentage change according to parts/ratio? If mixture is 1 : 1.5 : 3 in liters Shouldn't air percentage be ... 0 + 0.3 + 0.99 of 5.5 liter total mix = 1.29/5.5 = 23.45%
Sir, Just curious. If the void ratio of sand is 20%, and the aggregate is 34% then the volume of sand should be 80% and the Aggregate 66%, "multiplied by the ratio" of each. that means 1+(1.5x.8)+(3x0.66)= 1+1.2+1.98=4.18. Just my opinion. Thanks.
Any layman can understand. Just superb. Thank you Gentleman.
Yes, I sincerely thank you also.
This is the best info I ever seen. Thanks
Excellant explanation, very easy to understand and follow.
Thank you very much Sir🙏
finally somebody explained to me so I understud.
Super explanation bro..👏👏
Very nice video for civil engineer

Great explanation for lay-persons! Don.t waste time replying to stupid, crazy comments!
brilliant! so simple and straightforward
Considering 1:1.5:3 ration is by Volume;
*You said Air Voids and Volume shall in crease by 54%*
But if fine cement and water take up space of Air Voids (means Cement and water fill up the Void Spaces), then Volume must DECREASE
Why you said Volume will INCREASE??
Please explain
1 cum is now
0.28+0.42+0.84= 1.54
It does increase
1 cum is wet volume
1.54 is dry volume
From where you got these formulas for weight calculation of cement, sand, aggregate?
M20 grade concrete ratio
1:1.5:3 C:S:A
Total parts = 1+1.5+3=5.5
C= 1/5.5x 1.54= 0.28cum
S=1.5/5.5x1.54= 0.42cum
A=3/5.5x1.5= 0.84cum
VERY NICE
VERY HELPFUL

Interesting Explanation.
All aggregates were multiplied by 0.28m3. Am I correct to say Quantity of cement = ration(1) x 0.28 =0.28m3, Since you multiplied sand(1.5) and stone(3) by 0.28?
Very useful information thanks
Can you tell me what used to be the red clay of the kiln in the old days, which made such a strong masonry?
Red clay and limestone are bonding material .pozzolan cement
What is the proportion of aggregates 0.2, cement and sand for plastering purposes, to be used in plastering pumps equipments.
Thank you to advise on same.
Very informative but mason (mistry) rate cant be Rs 100 or it cant be less than labour or helpers
I understand the one, two, three mixture. depending on the size of aggragate the three is subject to be more or less.

Good day sir Why you use vol. Of cement in calculating vol. Sand and aggregate?
Thanks you in advance

Sir please make video on quantity of high strength concrete
Dry Volume/Wet Volume= 1.54
Therefore Dry Volume= wet volume x 1.54
What is .1 maison I didn't understand about that

On wastage of 3% for cement, how do you get 1.03?
Because you have 8×1.03=8.24 bags.

In terms of accuracy how do you compare this void % to DLBD method?
No

Where did the 1+1*54% come from

Pls explain why 0.1% for mason
Doesn't the percentage change according to parts/ratio?
If mixture is 1 : 1.5 : 3 in liters
Shouldn't air percentage be ...
0 + 0.3 + 0.99 of 5.5 liter total mix
= 1.29/5.5
= 23.45%

Yes
Super
why no wastage considered for Sand and Aggregates which is much more than Cement wastage
My question is what is the formula area 10by 10 to calculate the volume
Volume cannot be calculated on just two input figures, you need the third one. How deep is your slab? 3, 4 or 6 inches?
cement ke grade sirf 10 se kyu badtte what is the reason behind it
You forget to add the equipments
Cost of equipment is already considered in 5% Component
overhead cost will take care of that
thank you
