煤矸石对粉煤灰陶粒滤料性能的影响

The Effect of Coal Ash on Properties of Fly Ash Concrete

以粉煤灰、黏土为主料,添加不同比例的造孔剂煤矸石制备粉煤灰陶粒滤料,研究了煤矸石用量对粉煤灰陶粒滤料性能的影响,结果表明,随着煤矸石比例的提高,粉煤灰陶粒滤料的烧失量、吸水率及比表面积逐渐增大,而堆积密度、强度和耐酸碱性逐渐减小。

Using fly ash and clay as the main material along with a proper quantity of coal ash as pore-forming agent ,the experiment is conducted to produce fly ash concrete .T he affects of the coal ash dosage on properties are studied .The result shows ：Along with the increase of coal ash dosage , loss on ignition ,water absorption and specific surface area are gradually increased ,while the packing density ,strength and acid properties are gradually decreased .
