Degree.Therefore, how to guarantee temperature of concrete during casting process and initial curing, it is ensured that the pouring quality of concrete with
Concern of the intensity by more and more people.Low temperature casting concrete mainly uses two methods antifreeze at present:
First is that using antifreezing agent: the freezing point of concrete mixing water can be greatly lowered in antifreezing agent, prevent in mecystasis
With early concrete internal moisture freezing and expansion.It is antifreeze component that inorganic salts are generally added in antifreezing agent, such as nitrate, chlorination
Salt, nitrite etc..Although the antifreeze purpose of concreting can be realized by reducing freezing point, after adding antifreezing agent, mix
Contain a large amount of salt in solidifying soil, the ion in these salt can hinder the aquation of water and cement to reflect, so that hydration reaction speed subtracts
Slowly, the setting time of concrete is extended, and concrete is not set under teletostage low temperature condition is unfavorable for concrete for a long time
It is freeze proof.Even if this concrete finally condenses, also many defects can be formed in inside concrete, such as crystallize coarse, impervious
Can be reduced with endurance quality etc., and nitrite is noxious material, dramatically threatens the peace of concreting related personnel
Entirely.
Second is that using heat preserving method: the template as much as possible using glued board, plank etc. with certain insulation effect, with guarantor
The adiabator such as coverings such as cotton-wadded quilt, straw screen or mat or foam heat-insulating board exposure concrete surface and package steel form.But the heat preservation of this method
Effect is limited, and cannot be guaranteed the adiabatic condensation temperature of concrete.
