Thermal insulating cement

Abstract

The invention discloses thermal insulating cement which is characterized by comprising the following raw materials in parts by weight: 80 parts of cement clinker, 5-8 parts of gypsum, 10 parts of manganese slag, 5 parts of cement accelerator, 20 parts of vermiculite powder, 3-5 parts of pulverized fuel ash, 0.3-0.4 parts of alum and 12-16 parts of fluorgypsum. The cement is prepared by grinding 80parts of cement clinker, 5-8 parts of gypsum, 10 parts of manganese slag, 5 parts of cement accelerator, 20 parts of vermiculite powder, 3-5 parts of pulverized fuel ash, 0.3-0.4 parts of alum and 12-16 parts of fluorgypsum. A thermal insulating effect of the thermal insulating cement is increased by 40% as compared with the ordinary cement, and the thermal insulating cement has a good thermal insulating effect.

Description

technical field [0001] The invention relates to the technical field of cement, in particular to a heat-insulating cement. Background technique [0002] At present, the heat insulation and energy saving of housing construction is the top priority in saving work. The current approach is to add a layer of heat insulation to the building's outer wall to achieve energy-saving purposes. Wherein, although the method of adopting the polystyrene foam layer has considerable heat insulation effect, its construction is complicated, the cost is high, and it is neither durable nor easy to maintain. Although the method of heat-insulating coating is simple in construction and low in cost, its heat-insulating effect is very poor because the coating is too thin. In fact, the cement used in buildings is itself a kind of heat insulator, but its heat insulation effect is very poor, so changing the cement structure and improving the heat insulation performance of cement is undoubtedly a shortcu...
