Functional component: α-hemihydrate gypsum; standard JC/T 1023; appearance dry powder; net weight 25 kg. Gypsum-based self-levelling mortar can be applied in a single pass at thicknesses of 3-50 mm, achieving floor level tolerances within 2 mm. It supports mechanised pumping and automatic pouring, raising construction efficiency more than tenfold and sharply shortening project schedules. It offers good thermal insulation, resists cracking and bulging from thermal movement, and provides sound insulation.
