Abstract
The invention discloses water seepage-preventive cement, belonging to the technical field of cement preparation. The water seepage-preventive cement comprises the following raw materials in parts by weight: 65-70 parts of silicate cement, 30-40 parts of pulverized fuel ash with the particle size of 0.5mu m-1mu m, 5-8 parts of rosin with the particle size of 45mu m-50mu m, 1-5 parts of glass fiber with the particle size of 45mu m-50mu m, 5-10 parts of plaster, 2-3 parts of calcium hydroxide, and 1-2 parts of alum. The water seepage-preventive cement is prepared by comprising the following steps: firstly respectively crushing calcium hydroxide, alum and plaster according to the weight parts, and then evenly mixing the silicate cement, pulverized fuel ash, rosin and glass fibers. The water seepage-preventive cement provided by the invention has the advantages that the water seepage prevention performance is good and the production cost is low.
Description
Technical field
The invention belongs to cement preparing technical field, particularly relate to a kind of watertight cement.
Background technology
Cement, is the rigid inorganic coagulation material of a kind of powdery, stirs into slurry after adding water, and can harden in atmosphere or better harden in water, and can be firmly cemented together with the material such as sand, stone.Therefore, for a long time, cement, as a kind of important gelling material, is widely used in the engineerings such as civil construction, water conservancy, national defence.
Conventional cement can produce many holes or can produce small crackle in process of setting in spray process, and the existence of this some holes or crackle not only affects resistance to compression, the bending strength of the cement products be made up of it, and the cement products made also can be made to cause infiltration.Generally, people coat water-proof material by the top layer at cement products, prevent the generation of these cement products infiltration phenomenon.But, if doing so will increase the cost of cement products.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of watertight cement, and it is good that this watertight cement has water-impervious performance, the advantage that production cost is low.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of watertight cement, be made up of the raw material of following parts by weight:
Silicate cement 65 parts ~ 70 parts;
Granularity is 30 parts ~ 40 parts, the flyash of 0.5 μm ~ 1 μm;
Granularity is the rosin 5 parts ~ 8 parts of 45 μm ~ 50 μm;
Granularity is 1 part ~ 5 parts, the glass fibre of 45 μm ~ 50 μm;
5 parts ~ 10 parts, gypsum;
2 parts ~ 3 parts, calcium hydroxide;
1 part ~ 2 parts, alum;
Its preparation method is: by above-mentioned parts by weight, first respectively by calcium hydroxide, and alum, gypsum is pulverized, and then and silicate cement, flyash, rosin and glass fibre mix.
Owing to adopting technique scheme, the beneficial effect that the present invention obtains is:
It is good that watertight cement of the present invention has water-impervious performance, the advantage that production cost is low.
