![]() ![]() To Calculate How Much Square Foot Of Concrete Weighs: Always know that lightweight concrete is usually double the price of regular concrete. ![]() Normal weight concrete weighs about 18 lbs per square foot with a standard thickness of 1.5 inches and lightweight concrete weighs 14.5 lbs per square foot with a standard thickness of 1.5 inches.Ī large surface area would result in a considerable concrete weight saving and would be worth considering for flooring. To predict possible strength these strength tests are done at 24 hrs, 7 days, and 28 days in the lab. The density of concrete is checking strength by using test cylinders and a reduced density of normal concrete always means that there is a higher content of water which lowers the strength of concrete. Density is a simple mass-to-volume ratio and the most accurate way to calculate the density of concrete is to measure known volume and weigh it. ![]()
