There are various grades of concrete available in the market based on these ratios. Some of them are M10, M20, M30, M35, etc. So, what really does M10 or M20 mean or represent. “M” stands for “mix”. Mix represents concrete with designated proportions of cement, sand and aggregate.
Apr 08, 2018018332As grades of concrete vary between 15 to 80 Nmm 2. These grades differ on the basis of mix proportions. A good concrete should not fall under less than 5 of desired concrete strength. that means, We know that M20 grade concrete has a compressive strength of 20Nmm 2. A good concrete should not show less than 19Nmm 2 5 of compressive ...
The variable density is normally described in kg per m 3, where regular concrete is 2400 kgm 3. Variable density can be as low as 300 kgm 3 , 17 although at this density it would have no structural integrity at all and would function as a filler or insulation use only.

Jan 23, 2020018332The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isnt as complex as you may think because waters density is 1 gram per cubic centimeter or 1 gcm 3. Therefore, these numbers translate directly to gcm 3, or tonnes per cubic meter tm 3.
The density achieved depends on the type of aggregate used. Generally, the increased concrete density is achieved using barite, magnetite, or hematite aggregates. When using barite aggregate, the density of concrete is about 3400 kgm 3, which is 45 higher than that of ordinary concrete with magnetite the density is equal to 3500 kgm 3 —by 50 higher than that of normal concrete and with ...
