  • The role of aggregate in concrete countertop mix

    MaterialSizeShapeGradationMortar ConcreteConclusionMost natural stones and crushed rock are appropriate for use in concrete. Commonly used stones are quartz, basalt, granite, marble, and limestone. If a concrete countertop is going to be ground with diamond tooling, the aggregate will show, so aesthetics also affect the choice of aggregates.Problems arise with soft, reactive or weak stone or rock. Lightweight aggregates, a topic for another discussion, are also used in concrete.在concretecountertopinstitute上查看更多信息
