characteristics of coarse aggregates used in cement
Leaching Characteristics of Geopolymer Cement .
RCA is used in concrete in order to reduce the natural resource demands of concrete production and also to create an outlet for a large waste stream. The aggregates are produced by crushing pieces of concrete that are generated during demolition projects. This sort of demolition work is often aligned with largescale material disposal .

Nearly all natural aggregates originate from bed rocks. There are three kinds of rocks, namely, igneous, sedimentary and metamorphic. In such, many properties of aggregate depend on the properties of the parent rock itself. Coarse aggregates are classified into two main groups: (i) singlesize aggregate and (ii) graded aggregate.

Mixed Recycled Aggregates and Low Cement Content
Two mixed recycled aggregates (MRA1 and MRA2) with different percentages of ceramic particles collected on different days from a CDW treatment plant loed in Córdoba (South of Spain) were used. These aggregates were byproducts of the demolition of residential buildings. The grain size distribution of the materials is shown in Figure1.
