construction material obtained by alkaline activation of minerals contained in products and wastes from mining and working activity and process for producing such a construction material.

摘要

A building material (1, 2, 3) is described, obtained from an alkaline activation of sawing sludge of stone materials. The building material (1, 2, 3) comprises activating geo-polymerization solutions comprising sodium or potassium silicate dissolved in deionized water, amorphous silica with nanometer sizes and sodium or potassium hydroxide to allow making the building material (1, 2, 3) mainly composed of products and residues from extracting and working activities and lacking any other type of aggregated material. A process for producing such building material (1, 2, 3) is further described.
