Research on various Drymix mortar additives

Lightweight concrete slabs have been widely used in many projects as partitions of commercial and factory large bays. Cracking at the joints between panels is a common problem. As with plasterboard wall joints, tensile and shear stresses are the leading causes of cracking. The volume and quality of lightweight concrete slabs are more prominent than plasterboard, so the tensile and shear stress requirements are higher. Due to the difference in material and mechanical properties from gypsum boards, the caulking of lightweight concrete slabs must first solve the compatibility problem between lightweight concrete slabs and caulking materials. Give full play to the physical properties of the dry-mixed powder in the lightweight concrete slab caulking agent and improve the strength of the caulking agent. And it is reinforced by compounding anti-cracking fiber, which can avoid seam cracking to the greatest extent.
