how do I acurately figure required cement for a concrete pad?

Question

I am pouring a concrete slab and Iknow the dimentions, how do i figure how much cement to order

Answer 1

Cement is sold by the square yard. Calculate the number of square yards in the slab and order the cement.

Answer 2

Cement, most commonly referred to a "Portland" cement is a component of concrete along with water, fine and course aggregates. Most people use the terms interchangeably, but they are two different things. Mortar, which is used to keep brick or block walls together is a mixture of cement, sand and water. The ingredients aren't just thrown together, there are specific formulas and the amount of water included in the mix is critical, too much water weakens the concrete, which hardens through a chemical reaction, rather than drying out as most people think.

Answer 3

Average concrete pad thickness is 3.5 to 4 inches, at that thickness you get approx. 80sq feet from 1 yard of concrete. Be sure to ask for fiber reinforcement in the concrete you order.

Answer 4

just call the cement company and give them your figures and they will tell u and be very close nvr hurts to hv a little more than not enogh to finish job

Answer 5

just round off measurement..I go 10x10x3.5 is close enough to a yard. dont have to be on the money...reason.some areas are lower and or you have to raise a end to match existing landscape.
I`ve always been on without a problem.
