Impact Of Fine Brick Waste Aggregate Addition On Workability And Compressive Strength Of Self-compacting Mortar
Résumé: The objective of this research is to investigate whether or not a recycled material such as brick waste (BW) can be used in the concrete mixture as a self-compacting mortar. The possibility of substituting the sand by the brick waste is examined in depth and the brick waste was used as fine aggregate in different proportions varying from 5% to 25% by weight. A series of experimental work was conducted in order to determine the impact of the brick waste on the workability and the compressive strength of the self-compacting mortar. The workability of the concrete was determined by the marsh-cone test as well as by the rheometer test (for fresh mortar). Further the mechanical characteristics of selfcompacting mortar, the compressive strength and tensile strength (for hardened mortar) in bending were investigated and all tests were performed for 7, 28 and 90 days. The results show that brick waste increased the cohesion of the mortars due to its viscosity property. It was observed that the mortar prepared with BW has a low flowability compared to regular mortar. It was noticed that replacement of sand by the waste brick has produced a slight reduction in compressive strength.
