Using Hydrated Cement in Mortar for Masonry Walls

.Abstract
Large amounts of hydrated cement are accumulated on construction site due to improper storage and become a problem which requires getting rid of it. The objective of this investigation is to prepare a good cement from hydrated cement which is useful as a binding material, the effect of hydrated cement content as a partial replacement of cement on compressive strength and volume change of different mixes is studied. The investigation also extends to evaluate the structural performance of clay brick walls built from cement-hydrated cement mortar as a binding material, and to evaluate the effect of type of mortar, eccentricity and number of courses on compressive strength of clay brick prisms and to find the ultimate strength of load bearing clay brick walls and compare the experimental values of the ultimate strength of the wall with predicted values. The experimental results show that using hydrated cement as a partial replacement of cement up to 30% can be made without significant change in compressive strength compared with control mix.
