Aug 11 2018 Aggregates are one of the most important constituents of the concrete which give body to the concrete and also reduce shrinkage Aggregates occupy 60 to 80 of total volume of concrete So we can say that one should know definitely about the aggregates in depth to study about concrete Aggregate may be natural [ ].
Polyethylene Under Concrete Slabs Greenbuildingadvisor
Jul 04 2014 The crushed stone provides a capillary break that reduces the amount of moisture flowing upward from the damp soil to the permeable concrete Since the crushed stone layer provides a fairly uniform substrate it also may also reduce the chance that a concrete slab will be poorly supported by random pockets of soft easily compressible soil.
Recycled Concrete Aggregate
Recycled concrete aggregate (RCA) is the designation used in BS 8500 2 for recycled aggregate principally comprising crushed concrete Designations of recycled aggregate other than RCA are of lower quality and may contain significant quantities of masonry which would preclude or limit their use in structural concrete.
