Abstract

The invention relates to the technical field of cement for home decoration, and specifically discloses masonry cement for home decoration. The masonry cement for home decoration is prepared from the following raw materials in percentage by mass: 60-64% of clinker, 5-6.5% of desulfurized gypsum, 28-30% of limestone and 3-4% of slag. A production method for the masonry cement comprises the followingsteps: rolling clinker, desulfurized gypsum, limestone, slag and a grinding aid by adopting a roller press so as to obtain powder A; selecting the powder A by adopting a V-shaped powder selecting machine to obtain fine powder B and coarse powder C; feeding the coarse powder C into a ball mill for ball milling so as to obtain powder D; repeating the step 2 and the step 3 for the powder D, whereinthe fine powder B obtained in the step 2 is a finished masonry cement product. The masonry cement provided by the invention has multiple use functions such as easiness in mixing, easiness in smearing,proper initial setting time, high early strength, no bleeding, no layering, no bottom grabbing, strong cohesiveness, good durability, no brick cracking and no sand returning, and produces obvious social benefits.

Description

technical field [0001] The invention relates to the technical field of home decoration cement, in particular to home decoration masonry cement and a production method thereof. Background technique [0002] Masonry cement is a hydraulic cementitious material made of one or more active mixed materials or hydraulic industrial waste as the main raw material, adding an appropriate amount of Portland cement clinker and gypsum, and grinding. M. This kind of cement has low strength and cannot be used for reinforced concrete or structural concrete. It is mainly used for masonry, plastering mortar, cushion concrete, etc. of industrial and civil buildings. . [0003] With the rapid development of the decoration market, home improvement cement has become one of the development directions of urban decoration construction. Therefore, more new requirements are put forward for cement. For home decoration, the radiation of cement needs to be low, and at the same time, early cement producti...
