Influence of the Amount of Dimension Stone Waste on Water Absorption of Soil-Cement Bricks

This paper shows the use of dimension stone waste in manufacture soil-cement bricks. Initially, a sample soil was analyzed for mineralogical composition, particle size distribution (classifying it proportion silt, sand, and clay), physical performance by plasticity (Atterberg limits specified standard NBR 7180). A series soil/waste/cement mixtures were prepared with contents up to 90% wt.% waste. The samples characterized as microstructure, water absorption after 7, 14, 21, 28, 60 days. composition 20% presented individual average values according conditions established ABNT 10834 (≤22% ≤20% respectively) other similar results, indicating that could be used production bricks, helping reduce environmental impacts industry.
