How much concrete will a 94 pound bag of Portland cement make? | how many 94 Pound bags of Portland cement do I need for a Yard of concrete.
A bag of Portland cement weighs about 94 pound which yields about 1 cubic foot volume. Portland cement is mixed to Sand, gravel and water to form concrete. To understand about concrete mix ratio is the proportion of cement, Sand, gravel and water in concrete mix. How much concrete will a 94 pound bag of Portland cement make?
To create 3000 PSI strength concrete, ideal concrete mix ratio is 1:2:3 by volume. This means, 1 part of Portland cement mix to 2 parts of Sand and 3 parts of gravel. Or 94 pound cement bag (1 cubic foot bag) mixed to 2 cubic feet of Sand and 3 cubic feet of gravel which yields approximately 4 cubic feet of concrete mix after batching.
Each 94lb (pound) bag or sack of Portland cement, when used in the recommended 1:2:3 volumetric ratio (1 cement : 2 Sand : 3 gravel), will generate approximately 4 cubic feet of mixed concrete after batching. For one Yard or 27 cubic feet of concrete, or 7 bags of 94-pound of cement will be required.
Cement building material is mainly used as a binder or adhesive in concrete, which binds sand and aggregate. It is a basic material used for all types of construction, including housing, roads, bridge, dams, schools, hospitals, dams and ports, as well as for decorative applications for patios, ramp, floors, staircases, driveways, and pool decks.

How much concrete will a 94 pound bag of Portland cement make?
At standard Volumetric concrete ratio 1:2:3, (1 cement: 2 Sand: 3 gravel), a 94 Pound bag of Portland cement will make 4 cubic feet, 0.148 cubic Yard, 0.113 cubic meter, 600 Pound, or 0.3 tons of 3000 PSI Concrete.
To calculate yields of a 94 pound bag of Portland cement in concrete mix, add all the proportion of concrete mix i.e. 1 cubic foot of cement (94lb cement) + 2 cubic feet of Sand + 3 cubic feet of gravel = 6 cubic feet. Deduct 33% shrinkage, so final yields = 6 – (6× 33%) = 4 cubic feet approximately. Multiply total cubic footage 4 by 0.037 to get cubic Yard i.e. 4× 0.037 = 0.148.
Each 94-pound bag of Portland cement, when used in the recommended 1:2:3 volumetric ratio, will generate approximately 4 cubic feet of mixed concrete. For an area of 10 feet by 10 feet at 4” thick, you will need 33.33 cubic feet of concrete, or 8 1/2 bags of 94-pound of cement.
How many 94 Pound bags of Portland cement do I need for a Yard of concrete
At 1:2:3 volumetric ratio, to create one cubic Yard of 3000 PSI concrete mix, you would need 7 94- Pound bags or sacks of Portland cement. This means, 7 bags of Portland cement (7 cubic feet) mixed with 14 cubic feet of Sand and 21 cubic feet of gravel which yields 27 cubic feet or 1 Yard of concrete after batching. Total yields = total volume – 33% shrinkage = 42 – (42×33%) = 27 cubic feet approximately.
