Use of ceramivc wastes in structurals concretes

Abstract

The aim of this paper is to describe how waste material produced by the sanitary ceramics industry can be reused as aggregate in structural concrete mixes, as well as to analyse the economic and environmental benefits of this reuse. Firstly, aggregates were classified in order to assess their suitability for concrete mixing. Once the necessary assays had been carried out, different mixes were produced by gradually substituting part of the natural coarse aggregate with the recycled ceramic material. These concrete mixes were tested to determine their structural properties and results show that we can be optimistic when considering use of this kind of waste material in structural concrete.
