Abstract

The invention discloses a cement grinding aid for masonry cement. The cement grinding aid comprises the following components in percentage by weight: 60-80% of an aqueous polymer, 1-5% of cellulose ether, 5-20% of ethanediol and 10-15% of a sucrose ester. Compared with the frequently-used cement grinding aid in the market, the cement grinding aid disclosed by the invention has a good milling effect. The cement grinding aid has the effect of helping milling, besides, an appropriate amount of bubbles are added in the masonry cement, and the bubbles are maintained stable during construction; therefore, mortar or concrete prepared from cement produced by using the cement grinding aid has a good construction property.

Description

technical field [0001] The invention relates to the field of cement production, in particular to a cement grinding aid. 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 finely grinding, code-named 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. in industrial and civil buildings. However, during the construction process, the operability requirements of cement are relatively high, which is specifically reflected in the appropriate viscosity and operability time of mortar or concrete using cement. [0003] Cement grinding is an energy-intensive, low-efficiency process, where most of the energy is consumed in the grinding process. Therefore, the...
