Aggregates for Concrete - MERT YÜCEL YARDIMCI

Materials of Construction-Aggregates 2 What is Aggregate? Aggregates are the natural or artificial inorganic granular materials used with a cementing medium to form mortar or concrete. In concrete, the cement paste covers the aggregate particles surfaces, fills the voids between them, and bonds the particles together.

Effects of Aggregate on Concrete - Weebly

However, it is the gradation of the aggregates which has the greatest bearing on the workability and physical behaviour of wet concrete. Studies suggest that a well graded aggregate can significantly improve workability of concrete while in its hardened state also possess higher density and enhanced abrasion resistance (Quiroga Fowler, 2003).

During early microcracking studies, concrete was considered to be made up of two linear, elastic brittle materials; cement paste and aggregate; and microcracks were considered to be the major cause of concrete’s nonlinear stress-strain behavior in compression (Hsu , Slate, Sturman, and Winter 1963; Shah and Winter 1966).
