Properties of mortars with partial and total replacement of conventional aggregate by waste construction

Abstract

Environmental problems related to waste construction (RCC) permeate from the extraction of raw materials to its final disposal. The use of RCC in masses ceramics, concrete and mortar has been appointed as an important contribution. This work you assess the physical and mechanical properties of mortars with partial replacements (25% and 50%) of conventional aggregate for construction waste (RCC) come from a building of reinforced concrete structure and walls ceramic blocks. The mortars were tested to study their behavior fresh (consistency index and entrained air content) and solid (tensile strength in bending, compression strength and water absorption). The results approve of the use of the RCC, being limited to the grinding capacity of the same to a particle size that is interesting to the substitution of natural aggregates.
