Abstract

The invention discloses a magnesium sulfate cement, which comprises the following components by weight: 45-65 parts of fly ash, 10-20 parts of inorganic cementitious material, 10-20 parts of magnesium sulfate, 15-25 parts of plant fiber, 15-25 parts of polypropylene fiber, 15-25 parts of blast furnace slag, 10-20 parts of iron powder, 20-30 parts of gypsum powder, 10-20 parts of graphite powder, 15-25 parts of aluminum oxide, 10-20 parts of calcium carbide slag 15-20 parts of alkali-resistant glass fiber, 20-30 parts of potassium aluminum sulfate, 3-8 parts of sodium methyl silicate, 3-8 parts of triethanolamine, 3-8 parts of coagulation regulator, 3-5 parts of water-retaining agent , 5-8 parts of activator and 5-8 parts of deformation inhibitor. The cement has the characteristics of environmental protection, non-toxic, harmless, no cracks, small shrinkage and expansion coefficient; it has good fireproof, waterproof, anticorrosion and wind and rain erosion resistance, and is easy to fix and bond. The operation process is simple and the forming speed is fast.

Description

technical field [0001] The invention relates to the field of cement, in particular to a magnesium sulfate cement. Background technique [0002] At present, magnesium sulfate cement for construction is more and more favored by people because of its many advantages. However, some existing magnesium sulfate cements contain trace amounts of formaldehyde, which makes the use of this type of cement slightly toxic in the early stage; and in the long-term It is easy to be corroded when it is washed by rainwater, and it is easy to be melted when it is used in a kitchen stove; and during cement installation operations, the progress of the work is affected due to insufficient cement adhesion. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to th...
