PROPERTIES OF RECYCLED AGGREGATE CONCRETE

Mechanical properties of recycled aggregate are primarily dependent on the quality of the original cement mortar present in the aggregate, and also, as in the case with natural aggregates, depend on a number of other factors - the type of the original aggregate, structure, shape and size of grains, aggre-gate grading and so on.

Recycled Concrete Aggregates: Its Properties Uses

27-06-2019  Recycled concrete as aggregate contains residual adhered mortar on the particle of aggregate. Due to which the density of RCA is normally lower than the density of natural aggregate. The main reason for the lower density is that the adhered mortar is lighter in weight compared to the same volume of natural aggregate, which decreases the density.

01-05-2007  Recycled aggregates are composed of original aggregates and adhered mortar. The physical properties of recycled aggregates depend on both adhered mortar quality and the amount of adhered mortar. The adhered mortar is a porous material, its porosity depends upon the w/c ratio of the recycled concrete employed.

Performance of Recycled Aggregate Concrete

The compressive strength of recycled aggregate concrete with 60 % recycled aggregate, is about 76 % of natural aggregate concrete. The compressive strength increases as the percent of recycle aggregate in concrete mixes decreases. As the percent of Gaza sand increases the compressive strength of recycled aggregate concrete decreases for the same

When we estimate the concrete quantity, the aggregates will occupy 70 to 75% of the volume.. The classification of aggregates depends on the grain size, density, shape, and geographical origin. So the properties of aggregates will differ based on the classification, and it may influence the mix of the concrete and strength.
