Background technology
The heat-insulating and energy-saving of building construction is at present the most important thing in saving work.Current practice is to reach energy-conservation object at the additional one deck thermofin (layer of polystyrene foam or thermal insulating coating) of external wall.Wherein, though adopt the way of layer of polystyrene foam to have suitable effect of heat insulation, its construction is complicated, cost is high and also easy care not lastingly not.And although the way of thermal insulating coating construction is simple, cost is low, because of the too thin effect of heat insulation of its coating very poor.
In fact, the cement that buildings uses, itself is also a kind of thermally-insulated body, and just its effect of heat insulation is very poor, so change cement structures, improves a cement heat-proof quality shortcut beyond doubt.
Summary of the invention
The invention provides a kind of insulating cement.
The invention provides a kind of insulating cement, comprise each component of following mass fraction: cement clinker 60-70 part, gypsum 3-5 part, slag 3-5 part, manganese slag 6-8 part, Repone K 2-3 part, alum 0.1-0.2 part, fluorgypsum 10-15 part.
Further, comprise each component of following mass fraction: 65 parts of cement clinkers, 4 parts, gypsum, 4 parts, slag, 7 parts of manganese slags, 2 parts, Repone K, 0.15 part, alum, 12 parts of fluorgypsums.
The present invention also provides a kind of preparation method of insulating cement, is in 60-70 part cement clinker, to add gypsum 3-5 part slag 3-5 part, manganese slag 6-8 part, Repone K 2-3 part, alum 0.1-0.2 part, fluorgypsum 10-15 part, the common levigate cement products of making.
The effect of heat insulation of insulating cement of the present invention improves 30% compared with Portland cement, has good effect of heat insulation.
