Abstract
The invention discloses an improved concrete anti-cracking modifier, which is made by the following raw materials in parts by weight: 1.5-2.8 parts of sodium bicarbonate, 2.5-3.7 parts of polyethylene oxide, 2.5-4.8 parts of rubber powder particles, 1.5-2.2 parts of triethanolamine, 2.5-5 parts of slag powder, 1.6-3.7 parts of acetic acid lignin, 2.2-2.9 parts of 4-para phenyl phenol, and 0.8-1.2 parts of sodium methacrylic acyloxy acid. Compared with the existing modifier, the anti-permeability of the concrete is improved, so that the waterproof performance of the concrete is effectively improved, and the service life of the concrete is prolonged. During the drying process of the concrete, the acetic acid lignin, the rubber powder particles and the triethanolamine can form a three-dimensional thin film which can spread in the concrete, so that the adhesive force of components of the concrete is improved, and the anti-cracking performance of the concrete is also improved.
Description
Technical field
The present invention relates to a kind of improved agent on crack resistance of concrete properties-correcting agent that is chapped from the cold, 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 improved agent on crack resistance of concrete properties-correcting agent that is chapped from the cold is provided, and improved concrete impermeability, concrete water resistance is effectively improved, 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 improved agent on crack resistance of concrete properties-correcting agent that is chapped from the cold,
Raw material by following parts by weight is made: sodium bicarbonate 1.5-2.8 part, polyoxyethylene 2.5-3.7 part, rubber powder 2.5-4.8 part, trolamine 1.5-2.2 part, slag powders 2.5-5 part, acetic acid lignin 1.6-3.7 part, 4-p-phenyl phenol 2.2-2.9 part and cyano group and methacryloxy acid sodium 0.8-1.2 part.
Optimize, the above-mentioned improved agent on crack resistance of concrete properties-correcting agent that is chapped from the cold, by the raw material of following parts by weight, made:
0.9 part, 2.3 parts of sodium bicarbonates, 3.6 parts of polyoxyethylenes, 3.8 parts of rubber powders, 1.8 parts of trolamines, 4 parts of slag powders, 2.7 parts of acetic acid lignins, 2.5 parts of 4-p-phenyl phenols and cyano group and methacryloxy acid sodium.
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; During concrete is dry, acetic acid lignin, rubber powder and trolamine can form the three-dimension film that is dispersed throughout inside concrete, thereby have strengthened the bounding force between each component of concrete, have improved the concrete anti-ability of being chapped from the cold.
