掺锂渣粉再生砂浆砌体抗剪性能试验研究

Regeneration doped lithium slag powder mortar masonry shear performance test research

通过对烧结多孔砖分别与掺锂渣粉再生细骨料砂浆、普通砂浆配砌的共36个试件的受剪性能对比试验研究,发现掺锂渣粉再生砂浆多孔砖砌体抗剪强度虽低于天然砂浆多孔砖砌体,但可应用于实际工程。遂对再生砂浆砌体抗剪强度实测值与规范规定的平均值和设计值进行对比分析,提出了适用于乌鲁木齐地区再生细骨料砂浆多孔砖砌体抗剪强度的计算公式。

On sintered porous brick and recycled fine aggregate mortar doped lithium slag powder,the ordinary mortar with build by laying bricks or stones, a total of 36 shear performance contrast test research of the specimens, found doped lithium slag powder porous brick masonry shear strength is lower than the natural regeneration mortar mortar porous brick masonry, but as the growth of the regenera- tion of mortar strength grade, regeneration doped lithium slag powder mortar porous brick masonry shear strength of the relatively slow growth rate.Recycled cement mortar masonry shear strength value and the design value of the measured values and norms were analyzed, put forward the suitable for Urumqi area of recycled fine aggregate mortar porous brick masonry shear strength calculation formula.
