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.
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.
To make one cubic yard of concrete, you typically need about 1 part Portland cement, 2 parts sand, and 3 parts gravel. This translates roughly to 1 bag (94 lbs) of Portland cement, 0.5 cubic yards of sand, and 0.75 cubic yards of gravel. Adjustments may be needed based on the specific mix design and desired strength. Always consult local guidelines or concrete calculators for precise measurements.
A 15' x 20' x 4" slab needs at least 3.7 cubic yards.
No you can NOT(from my research)

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
