Durability of recycled aggregate concrete ScienceDirect

2013-3-1  One of the most unknown aspects of recycled aggregate concretes is related to their durability in aggressive environments. Also most of the results found in the literature are not comparable due to the heterogeneity of the recycled aggregates, water/cement ratios and types of cement used.

Durability of recycled aggregate concrete ScienceDirect

The durability of the concretes made with recycled aggregate is worse due to the intrinsic porosity of them. These differences decrease for low w/c ratios, as in this case the most influential factor is the low porosity obtained in the new improved cement paste. Considering the mechanical properties, the influence of the recycled aggregate is worse for the high w/c ratios.

Durability of Recycled Aggregate Concrete: An Overview

Recycled aggregate concrete (RAC) becomes a great concern for massive natural resoure comsumption and a huge con-struction waste.

Durability of recycled aggregate concrete using pozzolanic

2008-1-1  This suggests that recycled aggregate in concrete may impose a high risk to the durability of concrete structures in terms of chloride-induced corrosion of steel. Chloride ions will enter the concrete cover containing recycled aggregate more easily due to a higher rate of permeability altogether with water sorption, and subsequently reach the depth of the steel faster.

Durability of recycled aggregate concrete under coupling

2018-2-28  Meanwhile, a lot of studies have been conducted on the durability of RAC,,. Most of the results showed that the durability of RAC is generally lower than that of natural aggregate concrete (NAC), and it decreases with the increase of recycled coarse aggregate (RCA) replacement ratio,,.

2020-11-10  However, the utilization rate of recycled coarse aggregate (RCA) in China is still relatively low. In order to better improve the efficient utilization of waste concrete in the complex environment, the durability resistance of RAC with diverse substitution rates under the coupled action of freezing-thawing (F-T) cycles and chloride attack was investigated in this paper.

Strength and Durability Evaluation of Recycled Aggregate

2017-8-29  Table 1 Effect of recycled aggregate on concrete properties. Durability Durability of Recycled Aggregate (RA) can be influenced by coarse aggregate replacement ratio, concrete age, w/c ratio, and moisture content; generally, a lower w/c ratio generates a more durable concrete mix.

2015-5-14  This paper discusses the suitability of producing concrete with 100 % recycled aggregate to meet durability and strength requirements for different applications. 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.

Durability of recycled aggregate concrete A review

2018-5-1  Although the researches on recycled aggregate concrete (RAC) has been going on for nearly 70 years,the use of RA in concrete structures is still limited due to its long-term durability concerns. With the decrease of natural aggregate resources and the increase of waste concrete generation, RAC has become a hot research topic around the world.
