  • What are the Proper Concrete Mix Proportions?

    Sep 25, 2017· Cement is the bonding agent that holds the aggregate and sand of concrete together once it cures While very hard, the strength of cured cement does not compare to that of rock and sand As such, cement is the reason concrete has weak tensile strength and requires rebar Torque can easily break concreteConcrete is basically a mixture of aggregates and paste The aggregates are sand and gravel or crushed stone; the paste is water and Portland cement Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete Cement comprises from 10 to 15 percent of the concrete mix, by volumeFAQs | Cement AustraliaQuality Counts Make sure that your concrete producer purchases goodquality aggregate as verified by regular aggregate test results in compliance with ASTM C 33, "Standard Specifications for Concrete Aggregates" A history of good performance of a local aggregate also provides an indication of how well the material performs in serviceAggregate in Concrete The Concrete Network
