How to Estimate a Concrete Order | Family Handyman

Feb 12, 2020 · To determine the cost to pour concrete slab, use the following tips: Amount. Calculate the volume of concrete you need in cubic yards. The formula for cubic yards is this: Multiply the length (10 ft.) by the width (10 ft.) by the depth (.35 ft., or 4 in.) and divide it by 27 (the number of cubic feet in a cubic yard).

By measuring the cement, stone, and sand, you will have a consistent concrete mix throughout your entire project. 3000 psi concrete mix ratio. To produce a 3000 psi cubic yard of concrete (27 cubic feet) the concrete mixture ratio is: 517 pounds of cement or (234kg) 1560 pounds of sand or (707kg) 1600 pounds of stone or (725kg)

STRUCTURE magazine | Mass Concreting

Mass Concrete: When It Applies. The definition of mass concrete per the American Concrete Institute (ACI) is “any volume of concrete with dimensions large enough to require that measures be taken to cope with generation of heat from hydration of the cement and attendant volume change to minimize cracking” (ACI 116R and ACI 301).

Low CO2 Concrete

Most significantly, slag decreases Portland cement usage by as much as 50 percent, thereby diminishing CO 2 emissions. Typical mix designs for structural or paving concrete normally use substitution rates between 25 and 50 percent; high-performance and mass concrete applications can use substitution rates up to 80 percent.
