Relationship between the c/a proportion and properties in fresh state of mortars containing recycled ceramic aggregate

Abstract

In the search for alternative solutions for the recycling of ceramic waste from both of the industry as the demolition and as contribution to the conservation of the environment, treatment of this waste is being implemented so that they can be incorporated back into the construction industry, both in mortars and concretes. In this work has made an assessment on the properties of mortars containing ceramic waste (as aggregate), focusing on those presented in its fresh State (consistency, density and air content), since these can influence the quality of the execution of the work and even contribute in the properties of hardened state; therefore, mixtures with different percentages of arid ceramic instead of the usual aggregate, as well as with different relationships c/a were performed. The results show that the effect of ceramic aggregate content has greater influence than the relation c/a in the fresh properties of recycled ceramic mortars.
