Description
Technical field: the present invention relates to a kind of Hardenfast, it is a kind of novel alkali-free liquid, is used for sprayed concrete.
Background technology: at present, in engineering construction, the fast hardening concrete of injection is a certain amount of accelerating chemicals of admixture in concrete, can make very quick setting sclerosis in the very short time behind the concrete blunge of being prepared, and reach certain intensity as early as possible.Because at present the accelerating chemicals that uses is mostly based on calcium chloride, yellow soda ash etc., and the accelerating chemicals volume generally accounts for 4～8% of cement quality, and like this, the admixture accelerating chemicals is equivalent to bring into more chlorion of inside concrete and alkalimetal ion.As everyone knows, chlorion has the effect of quickening corrosion to the reinforcing bar of inside concrete, there is the then very easy alkali that causes in alkaline, suction back even generation are expanded, make concrete structure generation catastrophic failure, moreover yellow soda ash alkalescence itself is strong, can cause certain injury to positions such as workman's eyes, skins during construction.
The low alkali accelerating chemicals of no chlorine is the novel product that develops recent years, this series products has overcome the problem of chlorions a large amount of in traditional accelerating chemicals to the corrodibility harm of reinforcing bar, occur but much be still with powder form, a large amount of dust is still arranged in the course of injection, do not solve in the construction process harm to workmen's health, although it is low alkali accelerating chemicals in addition, but the introducing of alkaline matter still can cause the loss of late strength of concrete, be generally about 20%, still do not satisfy high-quality construction of shotcrete.
In order to satisfy high-quality construction of shotcrete engine request, extremely urgent to the research of alkali-free liquid accelerator.Nearest development is to be the material of main component with aluminium hydroxide, Tai-Ace S 150 or their composition, and not only non-alkalescence of this material but also alkali content extremely low (being generally less than 1%) have excellent rapid hardening epistasis energy early simultaneously.But, for number of C
3The difficult cement that A content is lower, these materials are difficult to satisfy the requirement of sprayed concrete.In this case,, but still can't provide enough early strengths, guarantee that the safety of engineering is carried out even, can shorten concrete time of coagulation by improving volume.
The development and research of accelerating chemicals new variety now, be not only with materials such as the traditional calcium chloride of other chemical substance replacement, yellow soda ash, make accelerating chemicals present non-alkalescence, more to shorten time of coagulation, promote the early strength development, improve concrete cohesiveness, the concrete whereabouts phenomenon that is not easy to have a rebound when making sprayed construction.
For the development of alkali-free liquid accelerator, China has carried out relevant scientific effort, but can supply the moulding product of suitability for industrialized production, excellent performance actually rare.Related products is mainly grasped in some famous transnational concrete admixture manufacturers, but because the unit price costliness is at present actually rare in the use of China.
Invent a kind of alkali-free, no chlorine, to the effect of inside concrete reinforcing bar non-corroding, have no irritating odor, cohesiveness is good, springback capacity is low, later strength storage rate height, with low cost, can be widely used in engineerings such as tunnel, culvert, bridge, supporting and repairing, the novel alkali-free quick-coagulant that can produce in enormous quantities is a purpose of the present invention.
Summary of the invention: the invention provides a kind of novel injection concrete alkali-free liquid setting accelerator, alkali-free quick-coagulant of the present invention, its compositing characteristic is to be host with Tai-Ace S 150, Sodium Fluoride, sal epsom, high efficiency water reducing agent, stablizer, suspension agent, defoamer, is a kind of broad-spectrum high efficacy accelerating chemicals of assistant agent.
