Aggregates SlideShare

Jan 14, 2015 Physical properties: • Specific gravity: usually 2.6 or 2.7 • Water absorption test: aggregates absorb water because of their porosity. If all the pores are filled with water the aggregates are said to be saturated and surface dry. If all the water inside the pores are removed by drying, the aggregates are said to have maximum dry weight.

Properties and Durability of Aggregate

Jul 14, 2007 The principal properties of aggregates is their tensile and compressive strengths, and their pore size and distribution. Most aggregates are inert, but some react with solutions to which they are exposed: salt solutions and alkalis of cement. Most durability concerns arise when they are used in concrete.
