Abstract
The invention discloses a composite anti-freezing agent which is prepared by mixing the following components: a water reducing component, an anti-freezing component, an early-strength component, an air entraining component and a delayed coagulation component. In the composite anti-freezing agent disclosed by the invention, the main components include the water reducing component, the anti-freezing component, the early-strength component, the air entraining component and the delayed coagulation component. Through scientific material selection and reasonable collocation, the concrete mixed with the anti-freezing agent of the formula has appropriate slump and setting time and facilitates concrete construction. The composite anti-freezing agent is free of chloride and low in alkali content, has certain water reducing property and early strength and relatively good anti-freezing ability and is suitable for concrete construction at negative temperature.
Description
Technical field
The present invention relates to build additive agent field, be specifically related to a kind of compound antifreezer.
Background technology
Antifreezing agent is to make concrete harden under subzero temperature, and is issued to the additive of estimated performance at regulation curing condition.It is a kind of material that can prevent moisture in material from freezing at low temperatures.
In China three northern areas of China, winter time is long, and sometimes for reasons such as durations, winter construction of concrete is essential, for ensureing concrete in winter quality under cold conditions, often uses antifreezing agent.
Summary of the invention
Present invention aim at, it is provided that the compound antifreezer that a kind of antifreezing effect is good, the technical solution adopted in the present invention is:
A kind of compound antifreezer, it is characterised in that mixed by weight percentage by following components:
Diminishing component
20-30 part
Antifreezing component
25-40 part
Accelerating component
25-45 part
Bleed component
5-15 part
Slow setting component
5-18 part.
One of preferably, described diminishing component is poly carboxylic acid series water reducer.
One of preferably, described antifreezing component is sodium sulphate.
One of preferably, described accelerating component is calcium formate.
One of preferably, described bleed component is alkylbenzenesulfonate.
One of preferably, described slow setting component is sodium gluconate.
The present invention provides the benefit that relative to prior art: the compound antifreezer of the present invention, and key component has diminishing component, antifreezing component, accelerating component, bleed component, slow setting component.By the selection of science, reasonably arranging in pairs or groups, the concrete slump using this antifreezing agent mix filled a prescription is suitable, and setting time is suitable, it is simple to concrete construction.This compound antifreezer without chlorine, low alkali, and there is certain water reducing ability and early epistasis, there is preferable antifreeze ability, be suitable for concrete construction under subzero temperature.
