Abstract
The present invention relates to building material technical fields, and in particular to a kind of aluminate cement.Include the ingredient of following parts by weight：Aluminate cement clinker：85 95 parts；Red mud：48 parts；Coagulant：12 parts；Water-reducing agent：23 parts.The present invention improves the early strength of cement, the intensity of particularly three hours or four hours by adding in coagulant and water-reducing agent.Shorten the demoulding time of cement, improve architecture production efficiency.In clinker suitable alkalinity is brought by adding in sodium hydroxide, accelerate the early hydration speed of clinker, further improve the early strength of cement, a small amount of iron ion is brought by adding in iron oxide in clinker, so that clinker burning temperature is relatively low, the heat consumption during clinker burning is reduced.
Description
Technical field
The present invention relates to building material technical fields, and in particular to a kind of aluminate cement.
Background technology
Cement is powdery hydraulicity inorganic coagulation material.Add water stir after into slurry, can in air harden or in water
In preferably harden, and can the materials such as sand, stone are cemented together securely.
The mixture of early stage lime and volcanic ash and modern lime pozzolanic cement are much like, are made of its cementing rubble
Concrete, not only intensity is higher after hardening, and can also resist the erosion of fresh water or brackish water.For a long time, it is as one
The important cementitious material of kind, is widely used in the engineerings such as civil construction, water conservancy, national defence.
Aluminate cement is a kind of important construction material, the early strength of cement it is higher, more contribute to shorten demoulding
Time improves production efficiency.
The content of the invention
The mesh of the present invention is, for problems of the prior art, proposes a kind of aluminate cement, improves cement
Early strength.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of aluminate cement includes the ingredient of following parts by weight：
Aluminate cement clinker：85-95 parts；
Red mud：4-8 parts；
Coagulant：1-2 parts；
Water-reducing agent：2-3 parts.
The aluminate cement clinker includes the ingredient of following parts by weight：
Lime stone：50-60 parts；
Aluminium slag：20-30 parts；
Bauxite：10-15 parts；
Additive：2-5 parts；
The additive is sodium hydroxide.
Further, the aluminate cement clinker includes the ingredient of following parts by weight：
Lime stone：55 parts；
Aluminium slag：25 parts；
Bauxite：12 parts；
Additive：4 parts；
The additive is sodium hydroxide.
Further, the additive further includes iron oxide.
Further, the weight ratio of the sodium hydroxide and iron oxide is 5：1.
The aluminium slag includes the ingredient of following parts by weight：
Al2O3：55-65 parts；
CaO：10-20 parts；
SiO2：2-5 parts；
MgO：4-8 parts.
By adopting the above-described technical solution, the beneficial effects of the invention are as follows：
The present invention improves the early strength of cement by adding in coagulant and water-reducing agent, particularly three hours or four hours strong
Degree.Shorten the demoulding time of cement, improve architecture production efficiency.In clinker by add in sodium hydroxide bring into it is suitable
Alkalinity accelerates the early hydration speed of clinker, the early strength of cement is further improved, by being added in clinker
Iron oxide brings a small amount of iron ion into so that clinker burning temperature is relatively low, reduces the heat consumption during clinker burning.
Specific embodiment
The present invention is described in detail below.
