Material, land plaster and sierozem power category air hardening type cementitious material, the scheme that the present invention is combined by the gentle hard material of hydraulic material carry
The integral strength of high material.
Specifically, building gypsum can be selected in the land plaster, and main component is beta-type semi-hydrated gypsum.Building gypsum is plastering
The major gelled material of gypsum plays a decisive role to the performance of plastering gupsum.Building gypsum fineness is smaller, plastering gupsum it is strong
Degree is higher, if but the fineness of building gypsum is excessive, it is likely that generate larger crystalline stress, while can also increase and need water
Amount, causes the hole in hardenite to increase, and reduces tensile strength, is easy to cause cracking, meanwhile, fineness is excessive to be adapted to additive
Property is bad.Therefore building gypsum of the present invention was preferably 200 mesh sieve, and screen over-size is less than 10% land plaster, and requirement is built
Build flexural strength ＞ 2.5MPa, compression strength the ＞ 4.9MPa of gypsum.
P.O42.5 type cement can be selected in the low alkali cement, and content is preferably 50-80 parts, more preferably 50 parts.Low alkali
Cement refers to the low cement of alkali metal oxide (potassium oxide and sodium oxide molybdena) content, and total alkali is with equivalent sodium oxide molybdena (Na2O+
0.658K2O it) calculates, low alkali cement requirement total alkali (equivalent sodium oxide molybdena) is less than 0.6%.The low alkali cement that the present invention adds in
The alkali content in gypsum can be reduced, destruction of the alkali to wall body surface decorative layer is prevented, building can be greatly prolonged
