The main functions of lightweight gypsum mortar in ceramic tile adhesive are as follows:

1. As the amount of cement increases, the original strength of tile adhesive increases. At the same time, its tensile adhesive strength after water immersion and tensile adhesive strength after heat aging It also increased accordingly. The cement dosage should be above 35%. 2. As the amount of reusable lightweight gypsum mortar increases, the tensile…
