  • Everything You Need to Know About Concrete Strength

    31-03-2019 · Traditional concrete is made of water cement air and an aggregate mixture of sand gravel and stone. The right proportion of these ingredients is key for achieving a higher concrete strength. A concrete mixture with too much cement paste may be easy to pour—but it will crack easily and not withstand the test of time.
