灰砂砖砌体的抗压强度较高,但抗剪强度较低,即抗震性能较差。怎样解决地震区用灰砂砖建筑房屋的抗震问题,是一个关系到灰砂砖稳步推广的重要问题。一、存在问题1.灰砂砖抗剪强度低,抗震性能差。至今不少生产厂家只是按老模式生产,只求外形尺寸及表面光泽合格,不求改进,砌体的抗震问题依然存在。2.灰砂砖耐碱,不耐酸,一般在碱性地基中比较适用。但是目前使用混乱,有的不管
Sandstone masonry compressive strength higher, but lower shear strength, that is, the seismic performance is poor. How to solve the seismic problem of building sand and sand bricks in earthquake area is an important issue that concerns the steady promotion of lime sand bricks. First, the existing problems 1. Sandstone low shear strength, seismic performance is poor. So far many manufacturers just according to the old model of production, only the appearance size and surface finish, do not seek improvement, masonry seismic problem still exists. 2. Ash sand brick alkali, acid, generally more applicable in alkaline foundations. However, the current use of confusion, some no matter
