Study the Strength Regularity of Recycled Masonry Mortar Produced with Recycled Ceramic Tiles

Abstract

Waste ceramic tiles are broken into sandy gravel to configure reclaimed sand instead of part of normal sand. Bending strength tests and compressive strength tests of mortar samples were carried out under different substitution rate of ceramic tile wastes sand in different curing time, which the ratio of cement and the consistency of mixture were fixed. The results indicate that strength grade of masonry mortar recycled by ceramic tile wastes under different substitution rates can be improved 1 or 2 grades, and the strength linearly increases as the curing time increases under the same substitution rate, and the growth rates of bending strength and compressive strength are inconsistent.

Experimental Research on Compressive and Shrinkage Properties of ECC Containing Ceramic Wastes Under Different Curing Conditions

“…In addition as a substitute for cement, qualified hardness and good wear resistance enable ceramic wastes to act as aggregates. Using recycled ceramic sand (RCS) as a replacement to partial sand can lead to various enhancements in the compressive strength, abrasion resistance, workability, resistance to chloride-ion corrosion of concrete, and reduction in the shrinkage of the mortar (Binici, 2007;López et al, 2007;Liu et al, 2015;Nie et al, 2015). However, it was also found that RCS slightly deteriorated workability and compressive strength of masonry mortar and recycled concrete in other studies.…”
