摘要
透水砖是一种新型生态环保建筑材料，具有良好的渗水性和保湿性，能很好的缓解由不透水路面铺装所带来的“城市荒漠化”和“热岛效应”。
本文以平顶山地区排放的粉煤灰为主要原料，采用正交实验方法分析粉煤灰掺量、助熔剂掺量、煅烧温度和保温时间对透水砖性能的影响，研究粉煤灰制备透水砖的可行性。
结果表明：各因素对抗压强度的影响程度依次是粉煤灰掺量、煅烧温度、保温时间、助熔剂掺量；对透水系数的影响程度依次是粉煤灰掺量、助熔剂掺量、保温时间、煅烧温度。
本次研究较合理的两组工艺参数为：（1）粉煤灰掺量45%，助熔剂掺量4%，煅烧温度1050℃，保温时间60min；（2）粉煤灰掺量45%，助熔剂掺量5%，煅烧温度1100℃，保温时间60min。
关键字：粉煤灰，透水砖，正交实验，抗压强度，透水系数
Abstract
The Permeable brick,a new kind of building material with wonderful water permeability and water-retention,can well retard "urban desert" and "heat island effect" which come from the road surfacing of bound waterproof pavement.
the thesis uses fay ash，which comes form Pingdingshan,as main raw material, analyzing the influence,which is caused by the dosage of fly ash,dosage of flux ,calcination temperature and soaking time,of the property of permeable brick by means of orthogonal experiment method ,in order to research the feasibility of making permeable brick with fly ash.
the results show that the influence of various factors ,implying on the compressive strength is different,top to bottom are the dosage of fly ash calcination temperature,soaking time and the dosage of flux.
two groups more reasonable technological parameters for this study are followed:(1)45% dosage of fly ash,4% dosage of flux,calcination temperature 1050℃,soaking time 60min.(2)45% dosage of fly ash,5% dosage of flux,calcination temperature1100℃,soaking time 60min.
Key words:fly-ash, permeable brick, orthogonal, compressive strength, permeability coefficient
