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.
In an M15 grade nominal mix, the typical ratio is 1:2:4 (cement:sand:aggregate). For 1 cubic meter of concrete, you would generally need about 7 bags of cement, as one bag of cement weighs 50 kg and approximately 0.035 cubic meters of cement is used. Therefore, the total quantity of cement needed for 1 cubic meter of M15 concrete is around 350 kg, which translates to about 7 bags.
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.

To determine how many bags of Portland cement are needed for a yard of concrete, you first need to know that a typical concrete mix consists of about 1 part cement, 2 parts sand, and 3 parts gravel by volume. A standard 94-pound bag of Portland cement yields approximately 0.5 cubic feet when mixed. Therefore, you'll need around 5 to 6 bags of Portland cement to make one yard (27 cubic feet) of concrete, depending on the specific mix design used.
Limestone is refined to make portland cement.
7 bags 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.

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.
