Dec 01, 2020 · “Typically, recycled concrete can be used in retaining walls, roads and sidewalks, but we are seeing a shift towards its increase in structures.” “As innovations continue in the composition of recycled concrete, we can envision a time in the future where recycled concrete can be a substitute within more structural applications as well.”
Resistance of Recycled Aggregate Concrete (RAC) Subjected
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%, 75 ...
Effect of nano metakaolin on compressive strength of
The compressive strength test block of recycled concrete formed in this experiment was the cubic specimen with a side length of 100 mm. The design strength of concrete was C30, and the water cement ratio was designed to be 0.55 according to the design code of ordinary concrete .The cement was replaced in equal mass by nano metakaolin, and its contents were 0%, 3%, 5% and 7% respectively.
Special Issue "New Trends in Recycled Aggregate Concrete
Recycled concrete aggregates (RCAs) generated from construction and demolition activities have been recognized as a feasible alternative to natural aggregates (NAs). Naturally, the columns fabricated with reinforced recycled concrete (RRC) have been proposed and investigated to promote the structural use of recycled aggregate concrete (RAC).
