  • Special Issue "New Trends in Recycled Aggregate

    However, as the recycled aggregate is poor quality, it is not used for concrete, and the Korean government has strengthened the quality standards for recycled aggregate for concrete. In this study, research was conducted on the mechanical and durability characteristics of concrete using recycled aggregate, after developing equipment to improve the quality of recycled aggregate to increase the

    Recycled aggregate concrete is in close proximity to normal concrete in terms of split tensile strength. The slump of recycled aggregate concrete is more than the normal concrete. At the end, it can be said that the RCA upto 50 % can be used for obtaining good quality concrete. MATERIALS International Journal of Pure and Applied Mathematics Special Issue 3243.

  • Recycled Concrete Aggregate - an overview |

    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. This is largely due to the potential for higher proportions of the masonry

  • Resistance of Recycled Aggregate Concrete (RAC)

    Recycled aggregates were widely used in the concrete industry as a replacement of natural aggregates in the last two decades. In this study, the resistance of concrete mixtures having various levels of recycled aggregate as a replacement of natural coarse aggregate to the attack of magnesium and sodium sulfates was investigated. Five mixtures made with 0%, 25%, 50%,

    Recycled concrete aggregate as such, holds original aggregate with hydrated cement paste. Hence first, that demolished concrete is cleaned from dirt and other loose particles. After that, it is broken into smaller pieces to produce aggregate known as recycled concrete aggregate. Recycled concrete aggregates are available in size of 20mm to 50mm.

  • Hemp and Recycled Aggregate Concrete -

    Recycled concrete aggregate (RCA) is obtained by breaking the lumps of old or demolished concrete works and extracting the coarse aggregates. One of the major reasons to use RCA in structural concrete is to have more environmentally friendly construction [4].The use of RCA on a large scale may help to reduce the effects of the construction on the environment by reusing waste materials and
