The water absorption for 20 and 13 mm recycled concrete aggregates was 5.3 and 8.2 %, respectively, compared to 1.0 % for the natural aggregate. High water absorption and lower specific gravity for 13 mm recycled concrete aggregate are due to increased amount of weak attached mortar compared to that for 20 mm recycled …

Abstract. Fine recycled concrete aggregates (FRCA) also called recycled sand, having particle sizes smaller than 5 mm, are essentially composed of mortar and hardened cement paste. Therefore they induce a large water demand which makes them hard to recycle into mortar and concrete. In this paper, the properties of mortars …

Includes first-hand experimental and simulation results on RAC. Includes some typical demonstration structures with RAC.
Coarse Aggregates (particulates greater than 4.75 mm) Coarse aggregates are standard rock particles and are quantifiable to a small extent. They can be characterized as either smooth, rounded, or angular (such as crushed stone). Various Examples: stone chips, clinkers, coal, and crushed gravel. Fine Aggregates …
The average flexural strength shown in Fig. 11 increased by increasing the percentages of replacement of coarse aggregates by recycled concrete aggregates after aging of seven and twenty-eight days. At the age of seven days the flexural strength increased from to 102.31%, 107.51%, 108.03% and 104.57% for 25%, 50%, 75% …

History. Recycled concrete aggregates or Crushed concrete aggregates has been in use since the ancient times, only to be integrated with gravel, sand, and cement to ensure durability. The practice was first recorded in the 1860s. US construction companies were reluctant to use the technique at first since crushing cured concrete …
This study aims to compare the potential environmental impact of the manufacture and production of recycled and by-product aggregates based on a life cycle assessment and to evaluate the environmental impact and cost when they are used as aggregates in concrete. To this end, the six potential environmental impacts (i.e., …

This study focuses on the production of structural concrete from prefabricated concrete waste. This thesis investigates crushed concrete aggregates (CCA) as aggregate replacements in an industrial ...
The results are encouraging and show that RCA can be used to produce 50 MPa structural concrete with durability properties similar to those of concrete made with aggregate. Previous investigations on recycled concrete aggregate (RCA) have largely been limited to the manufacture of nonstructural-grade concrete of up to 32 MPa-streng.
