摘　　要：以页岩和秸秆造孔剂作为原材料,探究不同掺量、不同粒径范围的秸秆造孔剂对页岩烧结微孔砖在抗压强度、体积密度、吸水率、显气孔率等方面的影响规律。试验结果表明:随着秸秆粉末掺量的增多和粒径的增大,试件标准稠度用水量增多,抗压强度降低和体积密度降低,显气孔率升高。通过控制秸秆粉末的掺量和粒径,能有效地改善页岩烧结砖的各项性能。This paper takes the shale and straw as raw materials to explore the influence regularities of the straw pore forming agent with different content and different particle size in compressive strength,the bulk density,water absorption and apparent porosity of shale sintered microporous materials. The test results show that along with the content and particle size of straw powder increases,the compressive strength and bulk density decreases,and water absorption and apparent porosity increases. It can effectively improve the various properties of sintered shale brick by controlling the content and particle size of straw powder.
