Aggregates for Concrete - Memphis

most limestones consist of calcite, dolomite, and minor amounts of quartz, feldspar, and clay. Weathering and erosion of rocks produce particles of stone, gravel, sand, silt, and clay. Recycled concrete, or crushed waste concrete, is a feasible source of aggregates and an economic reality, especially where good aggregates are scarce. Conven-

or dolomite minerals in the aquifer. Alkalinity and total hardness are usually nearly equal in concentration (when they are both reported in mg/L CaCO 3 (calcium carbonate) because they form from the same minerals. If alkalinity is Alkalinity much greater than total hardness, it may indicate that your water has passed through a water softener.
