Instruction》(Office of the State Council sends out (2016) No. 34), is distinctly claimed：Stop 32.5 grade composite Portland cements of production, emphasis production
42.5 and ratings above product；Accelerate development cement special, sandstone aggregate, concrete admixture, ready-mixed concrete, pre- sand cutting
Slurry, cement products.
At present, as P.C32.5 cement has formally been withdrawn from the market, commercial market starts to widely use P.C32.5R water
Mud.And common P.C32.5R cement is used for construction and decoration edge tiling, easily there is ceramic tile hollowing, obscission；As plastering a wall
Mortar, in fact it could happen that cohesiveness difference or the problems such as face checking.
Cement business is traditional core business of company, it is necessary to concentrates strength on consolidating and developing, not only to put forth effort to expand
Scale, will more focus on lifting development quality.The house ornamentation cement for being exclusively used in decoration marked is promoted in research and development, actively expands high-end, individual character
The production and sales of product, not only facilitate Products structural adjustment optimization, and be conducive to company exploitation safeguard commercial market,
Consolidate and expand occupation rate of market, while be likely to become the new profit growth point of company, improve company's profitability.
The content of the invention
The present invention is used for construction and decoration for common P.C32.5R cement, there are the easy hollowing of ceramic tile, comes off, cement cohesiveness
The problems such as difference and face checking, propose a kind of preparation method of decoration design for residence cement special.It is special using decoration design for residence
Good with cement cohesiveness, easily smearing property is good, and the performance characteristics such as good water-retaining property, can effectively improve construction working quality and efficiency.
In view of the above-mentioned problems, the application provides following solution, it is specific as follows
A kind of decoration design for residence cement, includes the raw material of following weight fraction：80~90wt% of cement semi-finished product, water

More preferably：Cement semi-finished product 90wt%, cement modifier 10wt%；And account for cement semi-finished product, cement
The foaming agent of conditioning agent gross weight 0.015wt%.
The cement semi-finished product is 50~55wt% clinkers, 4.0~5.0wt% gypsum, 20~35wt% agstones
End, 5~20wt% electroslag combined grindings are made.More preferably cement semi-finished product be 55wt% clinkers, 5wt% gypsum,
35wt% limestone powders, 5wt% electroslag combined grindings are made.
The cement modifier is by 40~45wt% kaolin, 15~20wt% silica, 15~20wt% oxygen
It is impervious micro- to change aluminium, 5~10wt% agstones, 9~12wt% water-reducing agents, 0.5~1.5wt% cellulose ethers, 10~15wt%
Brilliant cement waterproof agent combined grinding is made；The foaming agent is sodium alkyl sulfonate foaming agent.
More preferably cement modifier be by 40wt% kaolin, 18wt% silica, 15wt% aluminium oxide,
6wt% agstones, 10wt% water-reducing agents, 1wt% cellulose ethers, 10wt% permeability-resisting microcrystal cement waterproofing agent mixed powders are ground
Into.The water-reducing agent is lignin sulfonate water-reducing agent.
45 μm of the cement is tailed over no more than 6.0%, and mortar fluidity is not less than 200mm, and 3d compression strength is not less than
16.0MPa, 28d compression strength are not less than 34.5MPa, and (mortar mix ratio is water to mortar：Cement：Sand=0.85:1:3, sand
Modulus of fineness is controlled 1.6 ± 0.3) not less than 85%, coursing degree of mortar is not less than water retention in 10~20mm, consistency of mortar
80mm, mortar air content are not less than 3.0%.
The present invention also provides a kind of preparation method of decoration design for residence cement for the problem, includes the following steps：
(1) preparation method of cement semi-finished product：Clinker, gypsum, limestone powder and electroslag are mixed in a certain ratio, through ball mill
It is prepared after grinding 20min；(2) preparation method of cement modifier：By kaolin, silica part, aluminium oxide, lime stone
Powder, water-reducing agent, cellulose ether and permeability-resisting microcrystal cement waterproofing agent are mixed in a certain ratio, and are prepared after ball mill grinding 30min
Form；(3) cement semi-finished product, cement modifier and foaming agent are mixed in a certain ratio, through ball mill grinding, control out mill thing
45 μm of material is tailed over no more than 6.0%, and preparation is decoration design for residence cement special.
The advantage of the invention is that：First, selected raw material, manufactured cement radionuclide limitation reaches building body
Material production and marketing and the unrestricted standard of use, safety and environmental protection lower than ordinary cement Irradiation index, can greatly ensure that client's is strong
Health；Second, cement fineness control is smaller, and selects water-retaining property material, on the one hand can ensure the workability of cement, on the other hand may be used
Clinker volume is reduced, production cost is saved and reduces CO indirectly2Discharge；3rd, by the addition of cement modifier, ensureing
And while improving cement comprehensive performance, reduce the incorporation of clinker, reduce the exploitation of mineral resources, reduce cement into
This；4th, technological process is simple, can match existing production technology, realizes large-scale production；5th, the present invention is dedicated for family
Field is fitted up in front yard, highly practical, can effectively improve construction quality and construction efficiency.
The innovative point of the present invention is：
Selected cement raw material, the house ornamentation cement radioactivity of preparation are far below national standard and ordinary cement, are a kind of green
Color environment-friendly type fits up cement special, can greatly ensure the health of client.
Embodiment
To manufacture of cement, with raw material, (mainly clinker, mixing material and cement modifier, gypsum addition is smaller, influences to have
Limit, therefore do not detect) carry out the detection of radionuclide, it is ensured that and its manufactured cement radionuclide limitation meets building body
The unrestricted standard of material, testing result are shown in Table 1.Performance evaluation is carried out to mixing material, considers price, to cement Color influences
And water requirement size, select electroslag and powder to be prepared as mixing material as house ornamentation cement, specific data are shown in Table 2.Design three
(option b mixes foaming agent to kind of cement proportion scheme, and scheme C does not mix foaming agent, and contrast foaming agent is to cement performance and mortar performance
Influence), by cement grinding mill grinding, finished cement is milled into by certain Con trolling index, mix proportion scheme and Con trolling index are shown in Table 3.Inspection
Cement physical properties made of three kinds of schemes are surveyed, are contrasted with the current civilian cement in market, two prescription case of optimum selecting, comparing result
It is shown in Table 4.Mortar performance contrast is carried out to two prescription cases, comparing result is shown in Table 5.Last sample presentation to market carries out Blind Test, selects most
Excellent mix proportion scheme.
