Title Effects of High Strength aggregates on the properties of cement based composites
Abstract
Traditional concrete material with low strength and poor durability,
environmental compatibility are poor.High-strength cement-based composite materials by adding Mixed raw materials, thereby improving the uniformity of increased material strength.The project uses basalt aggregate, ceramic aggregate, steel balls and corundum aggregate aggregate as a reinforcing ingredients.Study of different preparation process on properties of aggregate in cement dispersion effect，Improve the interfacial adhesion with matrix，Preparation of high strength and aggregate reinforced cement-basedcomposites.Study on amount and variety of different macro-mechanical properties ofhigh-strength aggregates increased, analysis of microstructure of cement-based composites reinforced by high-strength aggregates, revealing themechanism of aggregate.Through enhanced role play different types of aggregate, improve mechanicalproperties and volume stability of cement-based composites, made design ofcement-based composites reinforced by high-strength aggregates and preparation method.
Keywords Aggregate,Cement-based composite materials，Strength
