Abstract
The invention belongs to the technical field of chemical industry of cement, and particularly relates to anti-corrosion scouring-resistant silicate cement. The anti-corrosion scouring-resistant silicate cement is prepared from the following raw materials in percentage by weight: 16-23% of calcium silicate, 13-18% of gypsum, 20-30% of cement, 8-17% of fly ash, 10-15% of silicate, 6-12% of volcanic ash mixed material and 10-25% of blast-furnace slag powder. A preparation method of the anti-corrosion scouring-resistant silicate cement comprises the following steps: adding 2-3 times of water into the raw materials, uniformly mixing, and standing for 1-2 hours. According to the invention, the traditional production mode is changed, and the combination of the materials of the silicate cement can be accelerated better, so that a compound chemical effect can be produced, thereby obtaining the silicate cement having better corrosion resistance and scouring resistance, and improving the durability of the engineering; and industrial waste slag is fully utilized, and atmospheric pollution is reduced, thereby ensuring that the anti-corrosion scouring-resistant silicate cement is green and environment-friendly. Thus, the anti-corrosion scouring-resistant silicate cement is a novel environment-friendly energy-saving material and has huge economic benefits and social benefits.
Description
Technical field
The invention belongs to the technical field of cement chemical industry, be specifically related to a kind of silicate cement of anticorrosive resistance to erosion.
Background technology
Silicate cement has fast solidifying, early strength and later strength are high, frost resistance is good, anti-carbonation properties is good, the advantages such as wear resistance is good, be widely used in building field, as on the ground, high-strength concrete and the prestressed concrete engineering of underground important structure, or be applicable to suffer within the scope of the fluctuation in stage of severe cold area the concrete works of multigelation circulation.Because its drying shrinkage is little, can be used for the concrete works under dry environment, can be used for road surface and ground surface works.
But at present, there are some problems in the silicate cement for above-mentioned engineering, hydration heat is large, corrosion-resistant, poor heat resistance, resistance to erosion effect is low, in the engineering of the corrosive medium contacts such as flowing freshwater or vitriol, or the engineering contacting with corrosive mediums such as seawater, mineral waters and having in the concrete works of anticorrosive, resistance to erosion, effect is all undesirable.
Summary of the invention
For the deficiencies in the prior art, object of the present invention is exactly the problem for existing some unstable properties of silicate cement, a kind of technical requirements that can meet different construction qualities is proposed, again can be anticorrosive, the silicate cement of the new function of resistance to erosion, be used for making up the defect of prior art.
A silicate cement for anticorrosive resistance to erosion is that the raw material by following weight per-cent consumption is prepared from:
After above-mentioned materials is added to 2-3 water doubly and mixes, standing 1-2 hour.
Described flyash comprises one or more in silicon-dioxide, aluminium sesquioxide, ferric oxide, magnesium oxide.
Described pozzolana mixed material comprises dehydrated kaolin and a small amount of basic oxide.
Compared to existing technology, advantage of the present invention is:
The present invention is not subject to the specify constraints of silicate cement standard when producing, the starting material of in the past producing silicate cement have been broken, changed traditional mode of production pattern in the past, the more excellent material that can promote silicate cement is combined, make it produce compound chemical effect, thereby obtain more having silicate cement anticorrosive, resistance to erosion, in various concrete workses and ground surface works, improved the weather resistance of engineering; Owing to having reduced the content of cement, increase new pozzolana mixed material and ground granulated blast furnace slag simultaneously, taken full advantage of industrial residue, reduced the pollution of atmosphere, environmental protection, is a kind of energy-saving material of novel environment-friendly, has larger economic benefit and social benefit.
