摘要
新型墙体材料的广泛应用使得普通砂浆黏结性能差的局限性凸现．采用聚乙烯醇缩丁醛和甲基纤维素对普通砂浆做合理改性，进行了96个抗剪试件的正变试验，并对试验结果进行正变分析．结果表明：块体类别是最主要的影响因素，其次是聚合物掺量和砂浆强度；当聚乙烯醇缩丁醛和甲基纤维素的掺量分别为水泥质量的20％-30％和0．05％。0．1％时，可较大幅度提高砂浆的黏结强度．
The deficiency of bond capacity of traditional cement mortar is exposed when the new walling materials arc used widely. In this paper, polyvinyl- butyral（PVB） and methyl cellulose（MC） are chosen as chemical additives to amend the property of normal mortar, orthogonal tests of 96 pieces of shear specimens are carried out, then orthogonal analysis of test results is performed. The results indicate that the sort of walling material is the most important factor in bond capacity of mortar, the mixed quantity of polymer and mortar strength follows, and there is a remarkable increase in mortar bond strength when the mixed quantity of PVB and MC is 20% - 30% and 0.05% -0. 1% respectively.
