SIZE EFFECT ANALYSIS OF COMPRESSIVE STRENGTH FOR …

An overview of study on recycled concrete has been given by Xiao et al[1]. However, because of the complexity of recycled coarse aggregates, conclusions made by different researchers are usually not very accordant, even opposite sometimes. To remove effects of experimental conditions, some numerical researches on meso-level was considered.

Recycled Concrete Aggregate - an overview | ScienceDirect Topics

Recycled concrete aggregate (RCA) is the designation used in BS 8500-2 for recycled aggregate principally comprising crushed concrete. Designations of recycled aggregate other than RCA are of lower quality and may contain significant quantities of masonry which would preclude or limit their use in structural concrete.

Crushed Concrete Aggregates - Properties and Uses of ...

Shear strength of recycled aggregate concrete is lesser than of normal concrete. This is because the recycled aggregate from field-demolished concrete for example can be relatively weaker than a typical natural aggregate. In general, there is a 10% decrease in strength when recycled coarse aggregates are used. Uses of Crushed Concrete Aggregates

A STUDY ON RECYCLED CONCRETE AGGREGATES

the recycled aggregate concrete is almost 85% and 80% of natural aggregate concrete. Amn on.et.al (2002), concrete having a 28 -day compressive strength of 28 MPa was crushed at ages 1, 3 and 28 days to serve as a source of aggregate for new concrete,

Using Recycled Concrete as Aggregate - Civil Engineering Notes

Based on various research it is generally accepted that around 30% of natural crushed coarse aggregate can be replaced with coarse recycled aggregate. It is done without significantly affecting any of the properties of the concrete. However it is advised to perform the various concrete tests by replacing some part of natural aggregate. This is done to determine the perfect proportions of concrete.

STUDY ON SILICA INFUSED RECYCLED AGGREGATE …

Recycled aggregate (RA) which is generated as a waste product of the construction world is identified as a sustainable material and lot of research works are done in this area [1-3]. Generally the application of RA is confined to low-grade applications because of its weak interfacial transition zone [4-6].
