Abstract
The invention provides an application of a novel concrete enhancer in concrete. The novel concrete enhancer includes following raw materials, by weight, 10-25 parts of ethylene glycol, 6-10 parts of isopropyl alcohol, 1-7 parts of sodium pyrosulfite, 2-7 parts of sodium hexametaphosphate, 5-12 parts of liquid alkali, 2-5 parts of triethanolamine and 3-8 parts of hydrophilic fumed silica. The concrete enhancer is mixed with cement, ore powder, fly ash, sand, water, stones and a water reducing agent in a large-size forced stirrer, wherein the use quantity of the concrete enhancer accounts for 3-5% of total weight of the cement, the ore powder and the fly ash. The novel concrete enhancer comprehensively improves mechanical performances of concrete and greatly improves the strength in various stages of concrete, thereby reducing the use amount of cement in the concrete. The novel concrete enhancer is toxic-free and harmless, is free of rust on steel bars, is good in adaptability with various cement and water reducing agents and is wide in market application prospect.
Description
Technical field
The present invention relates to building material technical field, particularly relate to the application of a kind of new concrete toughener in concrete.
Background technology
Concrete is the building structural materials of human maximum ancestor, it is through the simple and mechanical composite system mixed and stirred by gelling material (cement, flyash, breeze etc.), aggregate (comprising sand, stone etc.) and liquid medium (water, admixture etc.).Concrete is also the heterogeneous composite system of a kind of complexity, and the interfacial transition zone not between homophase affects the most important factor of concrete over-all properties, concrete many quality problems after all interfacial transition zone defectiveness produce.Along with the progress of science and technology, the use of concrete admixture and concrete intensifier, makes concrete performance obtain significant raising, but meanwhile also brings other problems, as: concrete flowability is little, cement consumption is large, water consumption is large.
Summary of the invention
In order to overcome the problem of prior art, the invention provides the application of a kind of new concrete toughener in concrete, it is to admixture strong adaptability, increase significantly late strength of concrete, nontoxic, reinforcing bar non-corroding is endangered, have good adaptability with various cement and water reducer, market application foreground is wide.
Technical scheme of the present invention is: provide a kind of new concrete toughener, with parts by weight, comprises following raw material:
The preparation method of described new concrete toughener, comprise the following steps: in proportion Sodium Pyrosulfite is dissolved in 3 ~ 15 parts of water, after adding liquid caustic soda, be warming up to 80 DEG C, stir 1.5 ~ 3 hours, then add wetting ability white carbon black and ethylene glycol, and be cooled to 35 DEG C of reactions, obtain intermediate reaction thing, after Virahol, Sodium hexametaphosphate 99, trolamine being mixed with intermediate reaction thing, obtain concrete intensifier.
By described concrete intensifier and cement, breeze, mixing in large-scale pressure type stirrer put into by flyash, sand, water, stone, water reducer, and mass fraction proportioning during mixing is as follows:
The consumption of described concrete intensifier accounts for the 3%-5% of the gross weight of cement, breeze and flyash.
The invention has the beneficial effects as follows: the concrete mechanical property of General Promotion, improve the intensity in concrete each length of time by a relatively large margin, thus reach the object reducing cement consumption in concrete, nontoxic, reinforcing bar non-corroding is endangered, have good adaptability with various cement and water reducer, market application foreground is wide.
Embodiment
A kind of new concrete toughener, with parts by weight, comprises following raw material:
The preparation method of described new concrete toughener, comprise the following steps: in proportion Sodium Pyrosulfite is dissolved in 3 ~ 15 parts of water, after adding liquid caustic soda, be warming up to 80 DEG C, stir 1.5 ~ 3 hours, then add wetting ability white carbon black and ethylene glycol, and be cooled to 35 DEG C of reactions, obtain intermediate reaction thing, after Virahol, Sodium hexametaphosphate 99, trolamine being mixed with intermediate reaction thing, obtain concrete intensifier.
By described concrete intensifier and cement, breeze, mixing in large-scale pressure type stirrer put into by flyash, sand, water, stone, water reducer, and mass fraction proportioning during mixing is as follows:
The consumption of described concrete intensifier accounts for the 3%-5% of the gross weight of cement, breeze and flyash.
The concrete mechanical property of General Promotion of the present invention, improves the intensity in concrete each length of time by a relatively large margin, thus reaches the object reducing cement consumption in concrete, nontoxic, to the harm of reinforcing bar non-corroding, have good adaptability with various cement and water reducer, market application foreground is wide.
The above is embodiments of the invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.All any amendments done within the spirit and principles in the present invention, equivalent replacement, improvement etc. all should be contained within right of the present invention.
Claims (3)
1. a new concrete toughener, with parts by weight, is characterized in that, comprises following raw material:
。
2. the preparation method of a kind of new concrete toughener according to claim 1, it is characterized in that, comprise the following steps: in proportion Sodium Pyrosulfite is dissolved in 3 ~ 15 parts of water, after adding liquid caustic soda, is warming up to 80 DEG C, stir 1.5 ~ 3 hours, add wetting ability white carbon black and ethylene glycol again, and be cooled to 35 DEG C of reactions, obtain intermediate reaction thing, after Virahol, Sodium hexametaphosphate 99, trolamine being mixed with intermediate reaction thing, obtain concrete intensifier.
3. the application of a kind of new concrete toughener in concrete according to claim 1 or 2, it is characterized in that: by described concrete intensifier and cement, breeze, mixing in large-scale pressure type stirrer put into by flyash, sand, water, stone, water reducer, and mass fraction proportioning during mixing is as follows:
