Abstract
The invention belongs to the technical field of water reducing agents and particularly relates to an efficient setting-retarding water reducing agent based on a setting retarder containing a carboxylic acid (carboxylate) radical. The setting-retarding water reducing agent comprises a water reducer, a setting retarder and a shrinkage reducing agent, wherein the content of the water reducer is 60-90 parts (by weight), the content of the setting retarder is 10-40 parts (by weight), the content of the shrinkage reducing agent is 0.01-0.03% of the total weight percent of the water reducer and the setting retarder, the water reducer is a naphthalene series water reducer, the shrinkage reducing agent is SRA-3, and the setting retarder is the setting retarder containing the carboxylic acid (carboxylate) radical. The setting-retarding efficient water reducing agent disclosed by the invention can be used for dispersing cement particles, so as to improve the workability of concrete; the unit water consumption can be reduced, so that the strength of the concrete is improved, and the durability of the concrete is improved; and the unit cement consumption can be reduced, and thus the cost of the concrete is reduced. The product disclosed by the invention has the effects of retarding concrete setting time, early strengthening, reducing water, 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 additive being of wide application in concrete admixture, and it is to have slow setting concurrently and the additive of mixing water amount is greatly reduced. With capital construction development, concrete performance is proposed more and higher requirement.
High performance Water-reducing Admixtures To Cements has high peptizaiton, can keep concrete bright degree of falling preferably. Penetrating into this kind of additive can make concrete have high-performance, it is possible to obtain high-strength high-performance concrete.
Existing retardation water reducing agent forms the thin film of one layer of indissoluble in cement particle surface difficulty, the aquation difficulty of cement being risen barrier action, hinders the normal hydrated of cement, these all can cause that the hydration rate of cement is accelerated, or deferred action is inconspicuous, shorten cement normal setting time. Therefore, exploitation one has great production practices and realistic meaning based on the efficient retardation water reducing agent containing carboxylic acid (salt) base retarder.
Summary of the invention
It is an object of the invention to solve above-mentioned technical problem and provide a kind of based on the efficient retardation water reducing agent containing carboxylic acid (salt) base retarder.
The present invention be achieved in that a kind of based on the efficient retardation water reducing agent containing carboxylic acid (salt) base retarder, include water reducer, retarder and economization agent; Described water reducer, retarder by weight respectively 60-90,10-40, described economization agent accounts for described water reducer, the total weight percent of retarder is 0.01-0.03%, described water reducer is naphthalene water reducer, described economization agent is SRA-1, and described retarder is containing carboxylic acid (salt) base retarder.
Described retarder includes the mixture of one or more in citric acid, malic acid, tartaric acid, salicylic acid.
The present invention can make cement particle disperse based on the efficient retardation water reducing agent containing carboxylic acid (salt) base retarder, improve concrete workability: unit consumption of water can be reduced, concrete strength is made to increase, and improve concrete durability: unit cement consumption can be reduced, reduce 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, effect outstanding feature. 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.
Detailed description of the invention
Below, it is further described in conjunction with the example substantive distinguishing features to the present invention and advantage, but the invention is not limited in listed embodiment.
A kind of based on the efficient retardation water reducing agent containing carboxylic acid (salt) base retarder, include water reducer, retarder and economization agent; Described water reducer, retarder by weight respectively 60-90,10-40, described economization agent accounts for described water reducer, the total weight percent of retarder is 0.01-0.03%, described water reducer is naphthalene water reducer, described economization agent is SRA-1.
Described retarder is containing carboxylic acid (salt) base retarder, including the mixture of one or more in citric acid, malic acid, tartaric acid, salicylic acid.
