摘要： A cementitious mixture including drinking water treatment waste (DWTW) solids, an aggregate, cement and water exhibits improved cement hydration, compressive strength and mitigated autogenous shrinkage. DWTW solids provide an internal curing agent for use with a cementitious mixture. DWTW solids are produced by a water treatment process of flocculating water to produce floc having entrained water, allowing the floc to settle out and dewatering the floc to produce DWTW solids. The DWTW solids form up to about 200 pounds per cubic yard of the cementitious mixture. The DWTW solids have a moisture content of about 5% to about 55% and a particle size of about 10 μm to 150 μm. The cementitious mixture may be cured to form concrete structural elements and products and masonry products. A method of using DWTW solids as an internal curing agent for cementitious mixtures produces cured concrete compositions having improved compressive strength and reduced autogenous shrinkage.
