The high-hardness cement provided by the invention is easily available in raw material source and simple and clear in preparation method, and is a novel cement product.
Description
Technical field
The present invention relates to a kind of cement, specifically a kind of high rigidity cement and its application, belong to building material field.
Background technology
Cement is a kind of powdery hydraulicity inorganic coagulation material.Cement is in powder, becomes slurry after the stirring that adds water, can be in sky
Harden in gas or preferably harden in water, and can be cemented together securely for the materials such as sand, stone.The history of cement can chase after
Trace back the mixture of roman's lime used in architectural engineering and volcanic ash.The mixture of early stage lime and volcanic ash with
Modern lime pozzolanic cement is much like, the concrete made with its cementing rubble, and after hardening, not only intensity is higher, but also
The erosion of fresh water or brackish water can be resisted.British J. Parker fires a kind of brown cement with marl within 1796, claims Luo Mashui
Mud or Parker's cement.British J. A Sipuding lime stones in 1824 and clay are fired into cement, the color after hardening and English
On Glan island, the local stone for building of Portland is similar, is named as Portland cement, and achieves patent right.Long-term with
Come, cement, as a kind of important Binder Materials, is widely used in the engineerings such as civil construction, water conservancy, national defence.With World Economics
Fast development, building, building industry also correspondingly flourishes.Cement, as a kind of most basic building material, has not
The cement of congenerous or several functions is developed, for example alumina cement, special cement etc..Although but current cement is multiple
Various, but it is as the change of cement purposes, novel concrete still has the huge market demand.
Generally, portland cement has higher hardness in itself.But some special engineerings need cement hardness higher, with
Reach expected load-bearing resistance to compression effect.In this case, the cement of high rigidity becomes a kind of R＆D direction.
Content of the invention
It is an object of the invention to provide a kind of high rigidity cement, to lift the high rigidity of cement.In order to solve above skill
Art problem, the present invention employs the following technical solutions：A kind of high rigidity cement and preparation method thereof, in units of weight portion, comprises
Following raw material：150 ~ 600 parts of clinker, ceramic 50 ~ 120 parts of grain, 25 ~ 60 parts of calcium sulfate, 10 ~ 16 parts of flyash, stabilizer
30 ~ 60 parts.
The present invention also provides a kind of preparation method of high rigidity cement, comprises the following steps：
S1：After clinker, ceramic grain, calcium sulfate, flyash mixing, homogenizing；
S2：Step S1 gained mixed material is preheated, decomposes；
S3：Step S2 gained mixed material is calcined at 1500 DEG C 30min；
S4：Stabilizer is added step S3 gained mixed material grinding, homogenizing.
Preferably, in step S1, the mixing time of material mixing is 1 ~ 2h, and rotating speed is 800 ~ 1000r/min.
Preferably, in step S2, mixed material preheating temperature is 800 ~ 1200 DEG C.
Preferably, in step S4, homogenising time is 15 ~ 30min, and rotating speed is 400 ~ 600r/min.
Preferably, a diameter of 0.08 ~ 0.1mm of clinker that in step S4, grinding becomes.
Described stabilizer be cement stabilizing agent, can be polymer-type can also be bentonite type.
The high rigidity cement constituent wide material sources of the present invention, add ceramic grain by clinker and are prepared from, operation
Simply, to compare other cement high rigidity higher for obtained cement, can meet the industry requirement to cement high rigidity.
The high rigidity cement of the present invention is suitable for producing chuck, chassis, pulling plate class cement products.Due to needing to increase electricity
The various bearing capacity of cable, therefore needs chuck, chassis, pulling plate to have higher hardness and good physical property.The present invention's is high hard
Degree cement can be used for designing according to C30 concrete, using water：Cement：Sand, stone=0.36:1:1.5:2.6 match ratio, through coagulation
Native preparation, Steel Reinforcing Bar Material, skeleton the step such as shape and enter mould, concrete cast, condense, for producing pulling plate, chassis, chuck
Cement products.When the high rigidity cement by the present invention is used for making pulling plate, chassis, chuck cement products, the system of concrete
Standby adopt order below：It is initially charged sand, is subsequently adding cement, add 2/3rds water, stir 30s, finally add stone
Sub and remaining water；During concrete cast, it is vibrated to vibrator closely knit after filling concrete, and the concrete stirring time once is less than
45min.
