Anti-freezing cement composition

Abstract

The invention discloses an anti-freezing cement composition. The anti-freezing cement composition is prepared from the following raw materials by mass: 60-70 parts of Portland cement clinker, 8-12 parts of glass fibers, 5-7 parts of gypsum powder, 2-5 parts of sodium carbonate, 7-9 parts of ethylene glycol, 6-10 parts of calcium metaaluminate, 4-8 parts of sodium thiocyanate, 5-7 parts of triethanolamine, 3-6 parts of alum, 4-7 parts of polyethylene glycol, 3-5 parts of unsaturated polyester resin and 2-4 parts of diglycolamine. The anti-freezing cement composition of the invention has good anti-freezing effect, strong adhesion, durability and good economical efficiency.

Description

technical field [0001] The invention relates to cement, in particular to an antifreeze cement composition. Background technique [0002] With the continuous development of the construction industry, the demand for cement is also increasing. In the construction industry, it is often necessary to construct outdoors. When the cold winter comes, it is necessary to add early strength agents and antifreeze agents to the cement to prevent The mixture of cement and concrete freezes and freezes at low temperatures. After adding antifreeze, it is not easy to stir evenly during the mixing process. When pouring, the antifreeze effect is often lost due to uneven mixing, and the quality of the building cannot be guaranteed. . Contents of the invention [0003] In order to solve the above existing problems, the present invention provides an antifreeze cement composition with good antifreeze effect, strong adhesion, durability and good economy. [0004] The technical solution adopted by...
