Concrete Aggregate Gradation In European Standard

  • Standards for cement, aggregates, admixtures

    Cements (for use in concrete) are factory-produced materials produced by either inter-grinding or blending their constituents at the cement works. They conform primarily to the British/European Standard BS EN 197-1. Some cements, such as sulfate-resisting Portland cement (SRPC) are however still covered by residual British Standards.
