Abstract
The present invention belongs to the technical field of water reducing agents, and particularly relates to an efficient retarding water reducing agent, which comprises, by weight, 60-90 parts of a water reducing agent, 10-40 parts of a retarder, and 0.01-0.03 part of a reducing agent, wherein the water reducing agent is a naphthalene water reducing agent, and the reducing agent is SRA-2. According to the present invention, with the efficient retarding water reducing agent, the cement particles can be dispersed, the workability of concrete can be improved, the water consumption per unit can be reduced, the strength of concrete can be increased, the durability of concrete can be improved, the cement consumption per unit can be reduced, and the concrete cost can be reduced; and the product has effects of concrete setting time delaying, early strength, water reducing and the like.
Description
Technical field
The invention belongs to retardation water reducing agent technical field, be specifically related to a kind of retardation water reducing agent.
Background technology
Efficient retarding and water reducing agent is a kind of admixture be of wide application in concrete admixture, and it is the admixture having slow setting concurrently and significantly reduce mixing water content.With fundamental construction development, more and higher requirement is proposed to concrete performance.
High performance Water-reducing Admixtures To Cements has high dissemination, can keep concrete bright degree of falling preferably.Infiltrating this kind of admixture can make concrete have high-performance, can obtain high-strength high-performance concrete.
Existing retardation water reducing agent forms the film of one deck indissoluble in cement particle surface difficulty, play barrier action to the aquation difficulty of cement, hinder the normal hydrated of cement, these all can cause the hydration rate of cement to be accelerated, or delayed coagulation is not obvious, shorten cement normal time of coagulation.Therefore, develop a kind of efficient retardation water reducing agent and there is great production practice and realistic meaning.
Summary of the invention
The object of the invention is to solve above-mentioned technical problem and a kind of efficient retardation water reducing agent is provided.
The present invention is achieved in that a kind of efficient retardation water reducing agent, comprises water reducer, retardant and economization agent; Described water reducer, retardant and economization agent are respectively by weight:
Water reducer 60-80,
Retardant 20-40,
Economization agent 0.01-0.03;
Wherein, described water reducer is naphthalene water reducer, and described economization agent is SRA-2.
Described retardant for containing carboxylic acid (salt) base retardant, to comprise in citric acid, oxysuccinic acid, tartrate, Whitfield's ointment the mixture of one or more.
The efficient retardation water reducing agent of the present invention can make cement particle disperse, and improves concrete workability: can reduce unit consumption of water, and concrete strength is increased, and improves concrete weather resistance: can reduce unit cement consumption, reduces Cost of Concrete.
Product of the present invention has effects such as delaying concrete coagulating time, early strong, diminishing.
Product of the present invention uses in concrete that to have volume low, the feature of Be very effective.Efficient retarding and water reducing agent cost of the present invention is low, and diminishing, retarding effect are good, has good economic benefit and social benefit.
