A 15' x 20' x 4" slab needs at least 3.7 cubic yards.
Forty five 80 pound bags of cement are needed to make one cubic yard of concrete.
for preparing cement mortar C.M.(1:6) number of cement bags required are nearly 5.14 bags.calculation: for preparing 1 cu.m wet C.M(1:6), dry material required is 25% extra.therefore dry material required is 1.25 cu.mhence cement required=1.25/(1+6)=0.178 cu.m(sand required=0.178*6=1.068 cu.m)density of cement=1440 kg/cu.m=>cement required in kg=0.178*1440=256.32cu.mwt. of cement in kg per bag=50kgtherefore no. of bags required is=26.32/50=5.14bags.thank u.
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.
To calculate the number of 80 lb bags of cement needed for a 10x12 foot slab that is 3 inches thick, first determine the volume of the slab in cubic feet: 10 ft x 12 ft x (3/12) ft = 30 cubic feet. One 80 lb bag of cement typically yields about 0.6 cubic feet of concrete. Therefore, you would need approximately 30 / 0.6 = 50 bags of 80 lb cement to complete the slab.

From the largest manufacturer of backaged Portland Cement, bags come in 92.5 lb bags. To be clear, cement is mixed with sand and often aggregate (pea-gravel up to much larger rocks or other things such as broken out concrete chunks) to make concrete. Portland Cement by itself has no structural integrity when mixed with water. It must be mixed with sand at a minimum to make a hard, useful product (concrete). Concrete comes in bags weighing 50, 60, and 80 pounds here in the US.From the largest manufacturer of backaged Portland Cement, bags come in 92.5 lb bags.

Limestone is refined to make portland cement.

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.
The raw materials needed to make ordinary portland cement are,Calcium oxidesilicon dioxideAluminium oxideIron oxideMagnesium oxideAlkaliessulphurtrioxide.
I think so ........

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.
