Abstract
The invention discloses antifreezing cement which comprises the following component percentage by weight: 0.01-0.3% of calcium metaaluminate, 0.05-0.9% of glass fiber, 0.05-0.65% of sodium carbonate, 0.1-0.3% of sodium sulfocyanate, 0.8-1.0% of tobermorite, 0.05-0.65% of sodium chloride, 0.08-0.95% of calcium chloride, 0.1-0.9% of triethanolamine, 0.1-2.0% of alum, 0.05-1.5% of gypse antifreezing component and Portland cement clinker in balancing amount. The antifreezing cement disclosed by the invention has a good antifreezing good and favorable long-term durability.
Description
Technical field
The present invention relates to a kind of antifreezing cement and preparation method thereof.
Background technology
Building trade generally all is at outdoor construction, and especially in the winter time, external temperature is in sub-zero zero, and cement can freeze, and therefore can't construct.At present, typically use admixture, prevent that such as hardening accelerator, frostproofer etc. cement and concrete mixture are freezing at low temperatures, hardening accelerator and frostproofer generally can only make the minimum use in the time of subzero 10 degrees centigrade of cement, and the moiety of hardening accelerator and frostproofer mainly is to contain villaumite, and chloride salt pair cement performance especially long durability all can exert an adverse impact.Simultaneously, Concrete antifreezer and hardening accelerator are percentum of cement, often exist and stir inhomogeneous situation, so that antifreezing effect is not obvious, can only use in some areas, can not solve the problem of all regions winter construction.
Summary of the invention
The objective of the invention is provides a kind of antifreezing cement for overcoming above-mentioned the deficiencies in the prior art.
For achieving the above object, the present invention adopts following technical proposals:
A kind of antifreezing cement, formed by the component of following weight percent: comprise 0.01～0.3% calcium metaaluminate, 0.05～0.9% glass fibre, 0.05～0.65% yellow soda ash, 0.1～0.3% Sodium Thiocyanate 99,0.8～1.0% hydrated calcium silicate, 0.05～0.65% sodium-chlor, 0.08～0.95% calcium chloride, 0.1～0.9% trolamine, 0.1～2.0% alum, the antifreeze component of 0.05～1.5% gypsum, surplus is Portland clinker.
The preparation method of antifreezing cement of the present invention comprises raw material pulverizing and oven dry, batching, grinding, calcining, stirring, grinding, and inserting described antifreeze component in the cement slurry the inside calcines, be added into antifreeze component in the grog after calcining, after putting into the abundant stirring of whipping appts, jointly grind and make finished cement.
The invention has the beneficial effects as follows, good freezing protection effect, and have good long durability.
