Experimental Study on the Mix Design and Fundamental Properties for Mixd Mortars Using Recycled Fine Aggregates
This paper concerns the use of recycled fine concrete and clay brick aggregates to respectively globally replace natural fine aggregates (sand) in the production of mixed mortar. The fundamental properties such as the compressive strength and the shrinkage ratio of mixed mortar made of the recycled fine aggregates are tested and discussed in detail. The experimental results indicated that it is viable to produce mixed mortar using recycled fine concrete and clay brick aggregates, the compressive strength of mixed mortar made of recycled fine aggregates is lower than that of mixed mortar made of natural fine aggregates and the shrinkage ratio of mixed mortar made of recycled fine aggregates is larger, cured in natural environment.
