Abstract
The present invention proposes a kind of preparation method of portland cement, and its step is as follows：（1）Meter weighs in parts by weight：80 100 parts of solid material, 10 15 parts of dicalcium silicate, 38 parts of iron powder, 38 parts of copper powder, 5 10 parts of water reducer, 26 parts of magnesia；（2）Above-mentioned each component is mixed evenly, environmental type product, saves the energy, reduce production cost.
Description
Technical field
The present invention relates to a kind of preparation method of cement, specifically a kind of preparation method of portland cement.
Background technology
At present, mass concrete engineering especially dam concrete, because hydration heat causes its internal temperature to raise,
Internal temperature is too high, and temperature difference between inside and outside concrete may be caused excessive, so as to produce larger temperature stress；When temperature stress is big
When the tensile strength of concrete, the cracking of mass concrete can be caused；Therefore, general mass concrete engineering is especially
It is Hydropower Dam engineering, the relatively small number of moderate-heat portland cement of generally use hydration heat does gel rubber material, but is answering
Find that the autogenous volumetric deformation for the concrete that moderate-heat portland cement pours has micro- contraction, so as to influence with, research process
The cracking resistance of concrete.In addition, destructive expansion is also to cause mass concrete especially big caused by alkali
Dam concrete produces one of the main reason for crack.With raising of the hydroelectric project to dam concrete technical requirements, only have
The problems such as cement for having the medium heat of hydration is and is not avoided that concrete alkali aggregate reaction in Dam Construction, concrete shrinkage causes
The risk of concrete cracking.Therefore, hydroelectric project dam then needs alkali content lower and has microdilatancy characteristic with moderate heat cement
Moderate-heat portland cement.
The content of the invention
The present invention proposes a kind of preparation method of portland cement regarding to the issue above, environmental type product, saves
The energy, reduce production cost.
Specific technical scheme is as follows：
A kind of preparation method of portland cement, its step are as follows：
（1）Meter weighs in parts by weight：Solid material 80-100 parts, dicalcium silicate 10-15 parts, iron powder 3-8 parts, copper powder 3-8 parts,
Water reducer 5-10 parts, magnesia 2-6 parts；
（2）Above-mentioned each component is mixed evenly.
Further, the solid material is counted by portland cement, lime stone, flyash, sand by 8 in parts by weight:3：
3:4 ratio of weight and number mixes.
Further, the particle diameter of the solid material is 0.1-0.4mm.
Further, the composition of the water reducer is counted as follows in parts by weight：
It is aminobenzenesulfonic acid 25-30 parts, phenol 2.5-3 parts, formaldehyde 5-6 parts, oxirane 3-5 parts, Lauryl Alcohol ester 1-3 parts, white
