众所周知,砌体系通过瓦工的操作将块材用砂浆粘结在一起而成的。灰缝砂浆在砌体中主要起两个作用:一是通过与块材的粘结作用,形成砌体的抗剪强度;二是在砌体受压状态下,起着传递压力的作用,从而势必对砌体的抗压强度产生影响。因此,合理地确定灰缝厚度,以及砌筑时对其进行控制,是砌体施工中的一个重要问题。一、灰缝厚度的确定 It is well known that brickwork is made by cementing blocks together by mortar. Mortar in the mortar in the mortar in the main two roles: First, through the bond with the block to form the shear strength of masonry; the second is in the masonry pressure state, plays the role of transmission pressure to It is bound to have an impact on the compressive strength of masonry. Therefore, it is an important issue in the masonry construction to reasonably determine the thickness of the mortar joint and to control it when masonry. First, the gray seam thickness to determine
