Sales of neat mortar materials for compressive strength of wall bricks

The mortar used for strength testing of wall bricks is composed of gypsum, fine sand with a particle size less than 1mm, and water. The weight ratio between gypsum and fine sand with a particle size less than 1mm is as follows: gypsum accounts for 50-70%, fine sand with a particle size less than 1mm accounts for 30-50%, and water accounts for 24-26% of the total weight of gypsum and fine sand. Gypsum refers to pure gypsum with a compressive strength greater than 22.0MPa and a flexural strength greater than 7.0MPa after 2 hours. The problem of excessive curing period and unstable testing of cement paste used in the strength test of this wall brick
