Abstract
The present invention relates to building material technical fields, and in particular to a kind of preparation method of Portland clinker.Include the following steps：It is crushed Step 1: lime stone, clay and gypsum are added in crusher；Step 2: by additive is added in broken mixture, it is then fed into grinder and grinds, raw material are made；It calcines, cools down Step 3: raw material are put into rotary kiln, Portland clinker is made.The present invention brings suitable alkalinity by adding in sodium hydroxide, accelerates the early hydration speed of clinker, improves the early strength of cement, shortens demoulding time, and the durability of cement later strength and cement is also secure.A small amount of iron ion is brought by adding in iron oxide so that clinker burning temperature is relatively low, reduces the heat consumption during clinker burning.
Description
Technical field
The present invention relates to building material technical fields, and in particular to a kind of preparation method of Portland clinker.
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.
Portland clinker is the important materials for producing portland cement, and the performance of Portland clinker determines silicon
The performance of acid salt cement.The raising of cement early strength helps to shorten demoulding time, improves production efficiency.
Invention content
The mesh of the present invention is, for problems of the prior art, proposes a kind of preparation of Portland clinker
Method improves the early strength of cement.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of preparation method of Portland clinker, including such as step：
It is crushed Step 1: lime stone, clay and gypsum are added in crusher；
Step 2: by additive is added in broken mixture, it is then fed into grinder and grinds, raw material are made；
It calcines, cools down Step 3: raw material are put into rotary kiln, Portland clinker is made.
The lime stone, clay, gypsum and additive parts by weight be：
Lime stone：50-60 parts；
Clay：20-30 parts；
Gypsum：10-15 parts；
Additive：2-5 parts；
The additive is sodium hydroxide.
Further, the parts by weight of the lime stone, clay, gypsum and additive are：
Lime stone：55 parts；
Clay：25 parts；
Gypsum：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 temperature of the calcining is 900-1400 DEG C.
The time of the calcining is 50-100min.
By adopting the above-described technical solution, the beneficial effects of the invention are as follows：
The present invention brings suitable alkalinity by adding in sodium hydroxide, accelerates the early hydration speed of clinker, improves cement
Early strength, shorten demoulding time, the durability of cement later strength and cement is also secure.It is brought by adding in iron oxide
A small amount of iron ion so that clinker burning temperature is relatively low, reduces the heat consumption during clinker burning.
