At present, most of the traditional urban and rural houses are built with brick-concrete structure. The brick-concrete wall is heavy and has poor thermal insulation performance, which increases the cost of heating in winter. In the field of wall insulation, secondary insulation measures are generally used, and wall construction generally adopts the construction method of frame-filled walls. However, due to the manual work, many procedures and long construction period, the overall construction materials and quality are difficult to control, resulting in cracks, water seepage, and shedding on the surface of the wall, which directly affects the wall and insulation effect and service life.

In the existing market, foamed cement insulation boards are often used in external wall thermal insulation systems. Its thermal insulation and flame-retardant properties are widely used in building exterior walls, but the existing foamed cement insulation boards have low strength. Cracks are prone to occur at the joints of the external walls, and the thermal insulation and sound insulation effects are poor.
