PROPERTIES OF RECYCLED AGGREGATE CONCRETE

recycled fine aggregate has a negative impact on the physical-mechanical properties of concrete, therefo-re, even though through a careful mix design and application of appropriate production technology these effects can be reduced to an acceptable level,

In this work, the effect of physical properties of recycled coarse aggregate (RCA) on the workability and mechanical properties of recycled aggregate thermal insulation concrete (RATIC) was studied. Two kinds of RCAs from different concrete waste plants were studied and the density, water absorption and crushing index of RCAs were analyzed.

Endodontic failures may occur as a result of leakage of irritants into the periapical tissues. 1 Therefore, an ideal orthograde and/or retrograde filling material should seal the pathways of communication between the root canal system and its surrounding tissues; thus, this material should be biocompatible and dimensionally stable. 2,3 This led to the development of mineral trioxide aggregate

The physical and mechanical properties of foamed concrete differ according to a different type of mixture and its composition. Therefore, Fly ash was used as fine aggregate. Six series of fly ash foamed concrete for target densities (1000, 1100,1200,13003

The physical and mechanical properties of different aggregates were tested, including the apparent relative density, water absorption, crushing value, and Los Angeles wear value. The chemical composition was measured by X-ray fluorescence (XRF).

Concrete with Recycled Aggregate: Evaluation of

Aggregate strength, gradation, absorption, specific gravity, shape, and texture are some of the physical and mechanical characteristics that contribute to the strength and durability of concrete. In general, quality of the recycled aggregate depends on the loading and environmental conditions that the demolished structures were exposed to.

The different physical and mechanical properties of the recycled coarse aggregate (RCA) are evaluated. RCA was obtained by crushing conventional concretes with different strength levels (different w/c ratios) containing four different types of natural coarse aggregates (three crushed stones and a siliceous gravel), which differ in shape, composition and surface texture.

Abstract: Concrete is one of moderately new materials, which is used widely because of its appropriate properties. Many Scientifics and researchers have tried to develop and utilize the beneficial properties of this new material and as a result its ingredients

wastes consist of natural aggregate and attached cement mortar. Due to the old, attached mortar, recycled aggregates have poor physical and mechanical properties. Hence, their use is limited to up to 30% replacement of natural aggre-gate with RCA in12,13

mechanical properties of lightweight aggregate concrete (LWAC) are discussed in this paper. The fly ash content ranged from 18% to 22% by cement volume, and the water-cement ratios are set to 0.3, 0.33 and 0.36 for each type of LWA.
