【摘要】：造纸白泥烧结页岩多孔砖是作为解决造纸厂碱回收过程产生大量的白泥而研发的一种新型墙体材料,因该砖在材料性能方面与普通砖存在差异,作为填充墙使用时其抗压强度计算没有相应公式。为了验证砌体规范抗压强度计算公式,通过取强度等级为MU5、MU7.5的砂浆,分别制作6组砌体进行其砌筑砌体的抗压性能试验。通过研究其破坏过程,得出其砌体抗压强度;并验证了此砖砌体可以用《砌体结构设计规范》中的计算公式计算其抗压强度。同时研究了造纸白泥烧结页岩多孔砖砌体的变形性能。通过分析,绘制出其应力-应变曲线,得出其弹性模量。
[Abstract]:White mud sintered shale porous brick is a new type of wall material developed to solve the problem of producing a large amount of white mud in the alkali recovery process of paper mill, because of the difference between the brick and ordinary brick in material properties. There is no corresponding formula for calculating the compressive strength when used as a filling wall. In order to verify the calculation formula of compressive strength of masonry code, six groups of masonry were made to test the compressive properties of masonry by taking mortar with strength grade MU5 and MU7.5. By studying the failure process, the compressive strength of the masonry is obtained, and it is verified that this brick masonry can calculate its compressive strength by the calculation formula in the Code for masonry structure Design. At the same time, the deformation properties of sintered shale porous brick masonry with white mud are studied. Through analysis, the stress-strain curve is drawn and the elastic modulus is obtained.
