Coal gasification slag all-component pervious concrete
The invention discloses coal gasification slag all-component pervious concrete. Ground coal gasification slag is taken as a silicon-aluminum raw material to prepare a coal gasification slag geopolymerwith good mechanical properties as a cementing material; and screened coal gasification slag is used as aggregate to prepare the pervious concrete which have adaptive mechanical properties and waterpermeability and has good wear resistance and water purification performance. The aggregate and the silicon-aluminum raw material used in the invention are both the coal gasification slag, so that theindustrial solid waste coal gasification slag is fully utilized, and the purpose of resource utilization is achieved. Meanwhile, the coal gasification slag contains a certain amount of activated carbon, so that the adsorption performance of the pervious concrete can be improved, and the pervious concrete which has adaptive mechanical properties and water permeability and has good wear resistanceand water purification performance is obtained.
本发明公开了一种煤气化渣全组分透水混凝土，以磨细的煤气化渣为硅铝质原料，制备出力学性能良好的煤气化渣地聚合物作胶凝材料；以筛分的煤气化渣为集料，制备出力学性能与透水性能相适应且具备良好耐磨性能与净水性能的透水混凝土。本发明使用的集料和硅铝质原料均为煤气化渣，充分利用了煤气化渣这一工业固废，达到资源化利用的目的。同时煤气化渣含有一定量的活性炭能提高透水混凝土的吸附性能，得到力学性能与透水性能相适应且具备良好耐磨性能与净水性能的透水混凝土。
