Additives Cellulose ether cellulose ethers are used as thickeners and water retention agent. Although the addition ratio is very low (0.02% -0.7%), but the effect is very important. Cellulose ethers used in dry mortar is mainly methyl hydroxyethyl cellulose ethers (MHEC) and methyl hydroxypropyl cellulose ethers. Referred to MC, MC features: adhesion and workability which is two factors influence each other; retention, avoid rapid evaporation - dry mortars prospects, so that the thickness of mortar layer can significantly reduce the general Plastering mortar construction projects, the largest amount plastering mortar. Its main function is to protect the walls, floors from the erosion of wind and rain and harmful impurities, improve moisture, corrosion, weather resistance competent mixed mortar, increase durability; while allowing the building to reach the surface smooth, clean and beautiful results. [2] surface mortar is usually divided into two or three layers construction. The layers of mortar requirements are different, and therefore each selected mortar are not the same. General acts underlying bond mortar grassroots require mortar should have good workability and high adhesive force, and therefore better water retention of the bottom surface of the mortar dry mortar use, or base materials absorb water easily affect the bond strength of mortar . Some grass-roots rough surface is conducive to bonding with the mortar. Plastering mainly to leveling the middle, and sometimes can be omitted to do. Mainly in order to smooth plaster surface appearance, so use sand.
