Other dry mortar additive, starch ethers can increase the consistency of mortar 2, entraining agent by physical action introducing microbubbles in the mortar, mortar density lower construction better. Mainly fat, sodium salt and sodium salt added in a proportion of 0.01% -0.06%. 3, Paul coagulant used it to get the desired setting time. Calcium common dry mortar plant, added in a proportion of 0.5% to 2.5% 4 retarder is mainly used in gypsum plaster and gypsum-based caulking compound. Mainly dry mortar acid salts, typically 0.05% -0.25% 5, hydrophobic agent (water repellent) prevents penetration of water into the mortar, mortar while still keeping an open state for water vapor diffusion.
