Experimental Research on Quality Parameters of Recycled Concrete

Experimental Research on the Wettability of Recycled Aggregate Concrete with Fly Ash

Material adsorption, the reverse process of evaporation diffusion, directly reflects the wettability of materials. Wettability is one of the main factors that affect the drying shrinkage of materials. A device that measures the wettability of recycled aggregate concrete (RAC) with fly ash is proposed in this study based on pore structure theory. The isothermal absorption curve of RAC is examine...

An Experimental Investigation of Using Recycled Aggregate in Concrete

One of the major challenges of our present society is the protection of environment; with respect to this some of the important elements are reduction of natural raw materials and consumption of waste materials. The recycled aggregate sample of size 20mm which is the maximum size of aggregate in reinforced cement concrete is collected from demolished structures in our surrounding areas and the ...

Effects of Recycled Concrete Aggregates on Properties of Asphalt Concrete

Research on the Parameters of Environment-Friendly Recycled Road Materials

The feasibility of propagating road materials in the use of contracture wastes especially contented great amount waste bricks were researched in three aspects: Performance of recycled aggregate, mechanical properties of renewable road materials, compression splitting indexes. Conclusions are as following: recycled aggregates contenting great amount waste bricks in place of natural aggregates ar...

Performance and Implementation of Low-Quality Recycled Concrete Aggregate

Our project seeks to greatly reduce the energy required for concrete production by using mostly recycled concrete. The use of recycled concrete aggregate (RCA) is not a new phenomenon, but has not been studied in the context of low-cost disaster reconstruction efforts, which was our focus—specifically, the 2010 earthquake in Haiti. In our experiments, we sought to replicate the variability in c...
