Abstract

Abstract

Using tailings, gypsum, cement and stone powder to prepare the no-fire brick, the mechanical properties are discussed by change of the proportion of tailings、gypsum、cement and stone powder, and the dosage of the water. The results show that the best preparation condition is that the proportion of tailings、gypsum、cement and stone powder being 2.5∶1.5∶1∶5, the water consumption accounting for 14% of the total solid materials. The prepared non-fired bricks can meet the standard requirements of iron tailings, the use of solid waste reached 25%, realizing the recycling of solid waste.
