Abstract
The invention discloses a concrete waterproof modifier, which is prepared by the following raw materials by weight: 1.2-2.6 parts of lithium silicate, 2.5-3.3 parts of dimethyl siloxane, 0.8-1.6 parts of aluminium hydroxide, 1.1-2.3 parts of sodium sulfide, 2.5-5 parts of gypsum, 1.5-2.8 parts of 4-tert-butylphenol, 1.8-3.3 parts of milled wood lignin and 1.5-3.8 parts of dimethyl siloxane. Compared with the prior modifier, the product can improve impervious capability of concrete, thereby effectively improving waterproofness of concrete and prolonging service life of concrete; the performance of concrete can be improved by reducing addition of water before solidification.
Description
Technical field
The present invention relates to a kind of concrete water-proof properties-correcting agent, belong to building material field.
Background technology
Conventional concrete main binding agent used is cement, and is generally portland cement, contains three calcium oxide, silicon oxide, ferric oxide, aluminum oxide and four calcium oxide etc.Portland cement mixes with water can make sand, rubble and other aggregate be bonded together, and in air returned.When in cement, the content of calcium oxide is greater than 1%, cement can react with the aggregate that contains silicon, silicon scholar rock and Wingdale, and formed compound can cause that inside concrete expands, thereby causes coagulation scholar inside and surface to occur crack.In addition, the hydration heat that during concrete hardening, hydration process discharges and build temperature variation and the concrete shrinkage acting in conjunction that temperature produces, consequent thermal stress and string stress are to cause structure to occur the principal element in crack.
Summary of the invention
The deficiency existing for prior art, technical problem to be solved by this invention is, a kind of concrete water-proof properties-correcting agent is provided, and improved concrete impermeability, and concrete water resistance is effectively improved, and extended concrete work-ing life.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is, a kind of concrete water-proof properties-correcting agent,
Raw material by following parts by weight is made: lithium silicate 1.2-2.6 part, dimethyl siloxane 2.5-3.3 part, aluminium hydroxide 0.8-1.6 part, sodium sulphite 1.1-2.3 part, gypsum 2.5-5 part, 4-tertiary butyl phenol 1.5-2.8 part, milled wood lignin quality 1.8-3.3 part and dimethyl siloxane 1.5-3.8 part.
Optimize, above-mentioned concrete water-proof properties-correcting agent, by the raw material of following parts by weight, made:
3.5 parts of 2.3 parts of lithium silicates, 2.8 parts of dimethyl siloxanes, 1.2 parts, aluminium hydroxide, 1.5 parts, sodium sulphite, 3.7 parts, gypsum, 2.4 parts of 4-tertiary butyl phenols, 3 parts of milled wood lignin quality and dimethyl siloxanes.
The present invention compares with existing properties-correcting agent, has improved concrete impermeability, and concrete water resistance is effectively improved, and has extended concrete work-ing life; Concrete performance can improve by reducing its addition that solidifies front water, but in order to obtain good workability, need in concrete, add a certain amount of water, so can select cement that water requirement is little to reduce the consumption of water, but in order to guarantee concrete workability, adding ester class emulsion is also a kind of extraordinary method, because emulsion has plasticizing effect to mixture, therefore can reduce the consumption of water; During concrete is dry, emulsion can also form the three-dimension film that is dispersed throughout inside concrete, thereby has strengthened the bounding force between each component of concrete.
Embodiment
embodiment 1
The present invention is a kind of concrete water-proof properties-correcting agent, by the raw material of following parts by weight, is made:
3.5 parts of 2.3 parts of lithium silicates, 2.8 parts of dimethyl siloxanes, 1.2 parts, aluminium hydroxide, 1.5 parts, sodium sulphite, 3.7 parts, gypsum, 2.4 parts of 4-tertiary butyl phenols, 3 parts of milled wood lignin quality and dimethyl siloxanes.
embodiment 2
The present invention is a kind of concrete water-proof properties-correcting agent, by the raw material of following parts by weight, is made:
1.5 parts of 1.2 parts of lithium silicates, 2.5 parts of dimethyl siloxanes, 0.8 part, aluminium hydroxide, 1.1 parts, sodium sulphite, 2.5 parts, gypsum, 1.5 parts of 4-tertiary butyl phenols, 1.8 parts of milled wood lignin quality and dimethyl siloxanes.
embodiment 3
The present invention is a kind of concrete water-proof properties-correcting agent, by the raw material of following parts by weight, is made:
3.8 parts of 2.6 parts of lithium silicates, 3.3 parts of dimethyl siloxanes, 1.6 parts, aluminium hydroxide, 2.3 parts, sodium sulphite, 5 parts, gypsum, 2.8 parts of 4-tertiary butyl phenols, 3.3 parts of milled wood lignin quality and dimethyl siloxanes.
The present invention compares with existing properties-correcting agent, has improved concrete impermeability, and concrete water resistance is effectively improved, and has extended concrete work-ing life; Concrete performance can improve by reducing its addition that solidifies front water, but in order to obtain good workability, need in concrete, add a certain amount of water, so can select cement that water requirement is little to reduce the consumption of water, but in order to guarantee concrete workability, adding ester class emulsion is also a kind of extraordinary method, because emulsion has plasticizing effect to mixture, therefore can reduce the consumption of water; During concrete is dry, emulsion can also form the three-dimension film that is dispersed throughout inside concrete, thereby has strengthened the bounding force between each component of concrete.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement, all should belong to protection scope of the present invention.
