Abstract:Waste ceramic tiles were broken into sandy gravel to configure reclaimed sand instead of part of normal sand. Strength tests and durability tests of mortar samples were carried out under different substitution rates of ceramic tile wastes sand in different curing time, which the ratio of cement and the consistency of mixture were fixed. The research results indicate that strength grade of masonry mortar recycled by ceramic tile wastes under different substitution rates can be improved 1~2 grades than common mortar, and the anti-frost property is improved by twice for the recycled mortar , and potential alkali silica reaction danger for recycled mortar is much smaller than that for common mortar. With the substitution rate of ceramic tile wastes sand increases, the strength increases, and anti-frost property increases at later period. At later stage, the common mortar has a tendency to arise shrinkage crack, while the recycled mortar has a tendency to arise swell crack.
