Environmental Causes of Cracking in Exterior Wall Insulation Mortar
Cracking caused by deformation of the wall structure: uneven foundation settlement, excessive spacing between transverse walls, failure to provide reinforcement at stress-concentrated corners of brick walls, overly large door and window openings, and improper placement of expansion joints can all lead to insufficient strength, stiffness, and stability in the wall, resulting in structural deformation cracks and subsequent cracking of the mortar layer.

The Role of Polycarboxylate Superplasticizers in Mortar and Concrete
Water-reducing agents primarily enhance the strength of mortar; they are admixtures that reduce water content and improve strength without compromising the workability of mortar and concrete during placement. Polycarboxylate superplasticizers are a new generation of high-performance water reducers developed in recent years, characterized by outstanding water-reducing efficiency, flowability, and penetrability. They significantly increase the strength of cement mortars; however, their production process is complex, and their cost is slightly higher than that of other water-reducing agents.

The aggregate used in thick-layer self-leveling screeds is fine aggregate with a particle size range of approximately 40–120 mesh. Experimental results demonstrate that such fine aggregate exhibits excellent flowability and strong particle suspension, which effectively enhances the flow characteristics and mechanical strength of the self-leveling material. With the development of industrial production, the volume of industrial waste has grown substantially, encompassing a wide variety of types and complex compositions, making its treatment particularly challenging.
