Preparation of Permeable Paving Bricks via Geopolymeric Method
摘要
Abstract
The development prospect of permeable brick was introduced.A kind of non burning permeable brick was developed with fly ash and long tailings as main raw materials by using the mechanism of mineral polymerization.Meanwhile, the influence of sand to cement ratio and aggregate size on permeable brick was studied.The results show that permeable coefficient increases, splitting tensile strength and flexural strength decreases of sample as aggregate diameter grow.The permebale coefficient increases,splitting tensile strength and flexural strength decreases of samples with the increase of the ratio of aggregate and cementing materials.The structure model and mechanism of permeable brick are also discussed.It is found that the ratio of sand to cement affects the effective void of the product, and then affects the permeability of the product.关键词
