摘要
粉煤灰在我国坏境污染中占有相当比例，用粉煤灰制成的彩色人行道地砖是治理其污染的有效途径．研究表明，粉煤灰掺入量在４０％～６０％时，成型压力在９～１１ＭＰａ之间，粉煤灰彩色人行道地砖性能达到ＪＣ４４６—９１混凝土路面砖质量标准．
The pulverized coal ash in China makes up a large Portion of the pollution. To make colour walkwcy brick by pulverized coal ash is an effective way of controlling pollution.The results show that the function of colour walkway brick by pulverized coal ash can reach the standard JC446- 91 of the walkway brick by cement when the content of pulverized coal aSh in it is about 40%-60% and the shape- pressure is between 9-11 MPa.
