Abstract
The present invention relates to low-alkali high-strength cement which comprises the following mineral clinker components by weight: 20 to 30 parts of C4A3S, 20 to 30 parts of C2S, 15 to 30 parts of C3S, 5 to 15 parts of CaSO4, 5 to 10 parts of C4AF5 and 2 to 5 parts of C3A2. The present invention also contains 5 to 10 parts of CaCO3 or/and 5 to 10 parts of SiO2 used as an additive. The present invention has the characteristics of low alkali, high strength, rapid hardening, rapid drying, etc. The pH value of the cement of 1 to 7 days is 8 to 9.5.
Description
Technical field
The present invention relates to a kind of cement, particularly relate to a kind of low alkali cement.
Background technology
Its major ingredient of existing low alkali cement is anhydrous calcium sulphoaluminate, Dicalcium Phosphate (Feed Grade) and a small amount of gypsum, and its pH value of 1～7 day is 10.5～11.5, and pH value is higher.When being used for cement products such as GRC member when it, the compositions such as fiber in these goods can be comparatively fast ineffective under the corrosion of alkali lye.In addition, performances such as the setting time of existing Portland cement and low alkali cement and intensity can not finely satisfy the needs of rapid construction.
Summary of the invention
The purpose of this invention is to provide a kind of low alkali high-strength cement, this cement has low alkali, high-strength, fast hard, fast characteristic such as do, and 1～7 day pH value of this cement is 8～9.5.
For achieving the above object, the present invention adopts following technical scheme: a kind of low alkali high-strength cement, contain following mineral clinker component: C by weight

The method for preparing above-mentioned low alkali high-strength cement is: will cooperate calcining with correction material, gypsum process with the corresponding aluminum raw material without calcination of above-mentioned mineral clinker, calcareous raw material, clayey raw material, and mix the levigate mixing of proper amount of gypsum again, and can make.
Also can contain CaCO in the low alkali high-strength cement of the present invention
35～10 parts or/and SiO
2Make addition material for 5 parts～10 parts.
The salient features of low alkali high-strength cement of the present invention is as follows: time of coagulation: about about 10 minutes of initial set, about 1 and a half hours of final set, ultimate compression strength (Mpa): 32.5/ day, 45.3/3 day, 56.5/7 day, folding strength (Mpa): 6.8/ day, 7.5/3 day, 9/7 day.
