Description
Technical field
The present invention relates to a kind of additives for building materials, specifically a kind of antifreeze alkali-free liquid accelerating agent and its preparation
Method, suitable in tunnel, underground mine engineering, harmful solonchak medium engineering and the work for needing to construct under environment in winter
Journey belongs to accelerator field.
Background technique
Accelerator is the additive for hardening cement rapid condensation, is mainly used in construction of shotcrete.Tunnel,
In the engineering constructions such as underground mine；Construction of shotcrete has the unrivaled superiority of normal concrete, has become this
The necessary measure of class engineering.The effect of accelerator is to speed up the condensation hardening of gunite concrete, improves its early strength, is in this way
Rapid construction is laid a good foundation.Simultaneously during some severe cold areas and winter construction, concrete will receive certain freeze injury
Effect, is greatly reduced the intensity of concrete, influences construction quality.
Currently, the development of wet-spray technique in recent years extends spray both at home and abroad still without similar products in well known technology
Penetrate the use scope of concrete.Liquid accelerator for wet shotcreting includes alkali accelerator and alkali-free quick-coagulant, from it
Had the following problems from the point of view of: alkali content is high, 28d (28 days) intensity than reduction, stationary phase is short, energy consumption is high in production process
Deng.It simultaneously in existing accelerator product, is unable to meet the construction requirement under subzero temperature, increases difficulty of construction and construction week
Phase.
In general, accelerator of the alkali content lower than 1% is known as alkali-free quick-coagulant, in existing technique, there is alkali accelerator
Alkali content generally 18% or more；The alkali content of low alkali accelerator is largely more than 6%；And certain alkali-free quick-coagulants are due to formula
In introduce sodium, potassium ion, practical alkali content is often higher than 1%；It will affect coagulation in the accelerator incorporation concrete of high alkali content
The later strength of soil makes 28d intensity than reducing, and thus directly affects the durability of concrete structure, is unfavorable for engineering matter
The control of amount.
Using the accelerator of aluminium salt due to hydrolysis and solubility, the different degrees of sedimentation there are in Storage period, analysis
Brilliant problem affects the using effect of accelerator so that effective concentration reduces.Prior art production in, no matter have alkali or
It is different degrees of in alkali-free quick-coagulant production process to need to heat, it is higher to the requirement of equipment and energy consumption in this way, in some areas
Environmental problem may be faced and influence to produce.
Concrete make its intensity continuous to increase with hydration reaction, but the water for participating in hydration reaction only accounts for concrete
25% or so of mixture water requirement, remaining water are intended merely to improve the working performance of concrete mix.Under normal circumstances, it mixes
After solidifying earth forming, extra water can be evaporated in inside concrete over time；And in winter or some low temperature environments
In, the water in inside concrete hole can form hard bulk crystals under subzero temperature, so that just molding inside concrete knot
Structure is destroyed under the action of the ice of these bulk crystals swollen stress, concrete strength sharp fall.
Summary of the invention
To solve the above-mentioned problems, the present invention devises a kind of antifreeze alkali-free liquid accelerating agent and preparation method thereof, with water
Mud has stronger adaptability, and in use process, low energy consumption, functional, can reduce the freezing point of water under subzero temperature, makes the crystalline substance of ice
Lattice is made severely deformed, can not form the swollen stress of ice to destroy hydrated product construction, keep concrete strength impaired, guarantee simultaneously
The concrete constructed under subzero temperature have enough liquid waters can continue promote hydration reaction, increase concrete strength, reach or
More than concrete power receiving capability.
