Great test! I think this makes sense, actually. Portland cement isn't all that strong, by itself. It's the mix with the aggregates that make it stronger. Sand and gravel aren't just added to make the cost lower. Although that's a part of it, there's a point where the mix doesn't get any stronger. Here's the test I would love to see, just to bring it into perspective for folks that might not have the engineering experience. Find the best strength/weight ratio mix from your 1" tests. Then, pour whatever that is into a panel with the same length and width, but with the thickness needed to make it weigh the same as the 3:1 sand mix. My bet - that's going to be about 2.5" think, and it's going to end up supporting about 4 times the weight of the 1" concrete. Then if you want, make another version, with some 1x1" cutouts, running long ways, in the bottom of the panel. So that it looks like the underside of a pre-cast bridge deck, kind of. Then, I bet you get a panel that's 20-30% lighter than normal concrete, more or less, and maybe 2x as strong.
Good video, your experiments helped me to build my pizza oven and I appreciate that. I have another question, I'm trying to build firebricks for the bottom of the pizza oven, I'm looking something that I can replace with the time but durable to the use, fire etc., I found some videos that are mixing stucco, and sand but they crumble after some fires in the oven, do you have any idea or materials?
I do intend to do this but also this is a long term project I am working on. I intend to build and test more mix designs before I summarize the results.
@@creatingconcretei am still dont get it why always do a bearing test like in a flat surface w/o rebar as reinforced or even having a large spam... if you do the same test with a square o rectabgular material will be diffeent resualt... ypu should do a compresion test over a falt surface instead... its like you use foamumlar NDX foam ypu will get diferent point of view...
Your videos have useful information for my semi portable pizza oven project. Out of curiosity, what is are the dimensions or volume of the block? I'm trying to create a custom material in Inventor and would like to have a density of this particular mixture.
Definitely enjoying seeing the results of each mixture. Are you ever going to test with structure reinforcement’s with mixtures? Rebar, wire, Etc.?
Loving these. Looking forward to the final comparison edit to see how they all compare.

Good content! Can you sum it up and present table with all your dicferent results plus explanation?

I would be very interested in a compressive strength test. Also, have you considered testing a shredded expanded polystyrene mix?
I have not considered but I am not opposed to trying different mix formulations and aggregates
What is the volume of block?
Hello sir. Please Can you help me on an investigation of the bond behavior of the lightweight concrete beam?
Can you "dry pour" your mixes? Using vermiculite, pearlite, granulated styrofoam?
If you substitute some of the perlite for sand you may get a better result
try more perlite and less concrete. wrape the whole thing with fiber cloth. Should be much lighter and stronger
you measure it the same way three times, obviously it is the same.
can it replace drywall?
I would not. I am confident you would not get a professional quality finish and cracking would certainly be an issue.
