摘要
秸秆半碳化处理后,作为烧结制品的造孔剂可以制备轻质高强、具有良好保温隔热效果的建筑功能材料。用半碳化秸秆和未经半碳化的秸秆分别作为造孔剂,对比两种造孔剂对多孔烧结砖性能的影响。在相同的烧成制度下,掺加经半碳化处理秸秆的烧结砖试块与掺未半碳化秸秆的试块相比,掺量为20%时,烧成收缩及质量损失分别降低0.6%,0.9%;掺量为15%时,压强为10.3 MPa,满足GB-5101-2003《烧结普通砖》的要求,性能优于未掺半碳化秸秆的试块;而掺入两种造孔剂的试件的气孔率相差无几,为37.2%~43.8%,在相同掺量下,掺加半碳化秸秆的吸水率比掺加未半碳化秸秆降低0.8%,其在烧结砖内所形成的封闭孔数量多。
The paper researches and compares the effects of two kinds of pore formers of semi-carbonized rice straw and not semi-carbonized straw on properties of fired shale bricks. The test shows that the semi-carbonized rice straw is better than the not semi-carbonized rice straw, and the fired shale bricks accord with the demands of the standard of GB-5101-2003 fired common brick.
