Abstract
An eco-concrete prepared by silica-alumina based cementitious material was developed and defined as silica-alumina based concrete. Systematic properties investigation showed that the silica-alumina based concrete exhibited good mechanical properties, low shrinkage strain and superior durability including strong resistances to water penetration, carbonation, chloride penetration, freezing-thawing and seawater attack. These excellent performances can be related to the fact that it developed a dense and compacted interfacial transition zone between the cementitious matrix and aggregate, and the silica-alumina based cementitious matrix had a refined pore structure. Leaching toxicity and radioactivity results indicated that the silica-alumina based concrete is environmentally acceptable.
