~ 1 cu. ft.
3 cubic feet or about one-tenth of a cubic yard. Cement is generally quantified in yards or cubic yards. It takes 27 cubic feet (3x3x3) to make a cubic yard. Therefore 3 cubic feet is about .111 or about one-tenth of a cubic yard (3 divided by 27).
Limestone is refined to make portland cement.
A 15' x 20' x 4" slab needs at least 3.7 cubic yards.
No you can NOT(from my research)
OPC - Ordinary Portland cementOPC - Materials used - Argillaceous and calcareous materialsPPC - Portland Pozzolona CementPPC - OPC + Pozzolonoc materials(fly ash, volcanic ash, pumicite at the time of grinding).
To make Portland cement, you need to combine limestone, clay, and other materials in a kiln at high temperatures. This process, called calcination, creates a powder that is then mixed with gypsum to form the final cement product.
5 or 6. An 80 lb. bag of ready mix concrete will make about 1/2 cubic foot of concrete. A 94 lb. bag of portland cement mixed with 1 1/2 cu. ft of stone (coarse gravel) and 1 cu. ft. of sand will make 3 cubic feet of concrete or 6 times as much. (this is a common 1:2:3 mix) Quikcrete ready mix is often made with 1 part cement, and 2 1/2 parts each sand and stone. A 1:1 1/2: 3 mix is a stronger mix but you get less volume, at 5 1/2 cubic feet per bag of cement.

I think so ........
27 cubic feet in a cubic yard, so 5 cubic yards is equal to 135 cubic feet
Concrete is what you make a sidewalk from. To make concrete, you mix Portland cement, sand, gravel (aggregate) and water. The cement holds the aggregate together.
