Abstract
The invention relates to a concrete additive, which is composed of the following components in percentage by weight: 15.0 to 60.0 wt% of high efficient water reducer, 1.0 to 5.0 wt% of organic silicon waterproof agent, 0.5 to 2.0 wt% of beta group sodium sulfonate-formaldehyde condensate, 1.5 to 3.5 wt% of triethanolamine, 3.5 to 7.5 wt% of alkyl benzene sulfonate, 3.5 to 25 wt% of sodium sulfate, 3.0 to 5.0 wt% of silicone, and the balance being water. The provided additive has a waterproof and impact resistant performance, and is capable of prominently improving the strength and friction resistant performance of concrete.
Description
Technical field
The present invention relates to architecture engineering material technical field, specifically concrete additive.
Background technology
Along with the development of science and technology, people are more and more high to engineering, construction quality and the requirement in buildings work-ing life.Use concrete additive be improve and improve concrete properties, meet the best of project durability requirement, the most effectively, one of the most easy approach.
Concrete additive kind is more, Various Functions.Use the additive of various different varieties, different effects can be reached.But when collocation uses, should be noted that the interaction of various concrete additive, type selecting, proportioning or addition manner are incorrect, by its concrete construction quality of serious shadow noon simultaneously.Therefore, under how meeting the requirements of the prerequisite of water-reducing rate, can not bleeding rate be increased, improve concrete mobility, can adapt to different cement type processed commodities concrete under the prerequisite that concrete can not be caused early to coagulate again, be the requirements at the higher level proposed concrete additive.
Summary of the invention
The technical problem to be solved in the present invention overcomes above-mentioned existing defect, provides a kind of concrete additive.
To achieve these goals, technical scheme of the present invention is as follows:
High efficiency water reducing agent: 15.0 ~ 60.0wt%, waterproofing agent of organosilicon: 1.0 ~ 5.0wt%, β base sodium sulfonate formaldehyde condensation products: the water of 0.5 ~ 2.0wt%, trolamine: 1.5 ~ 3.5wt%, alkylbenzene sulfonate: 3.5 ~ 7.5wt%, sodium sulfate: 3.5 ~ 25wt%, silicone: 3.0 ~ 5.0wt% and surplus.
Further, described high efficiency water reducing agent is the composite of methacrylic acid/e pioic acid methyl ester multipolymer and acid amides, and ratio is 0.5 ~ 1.5:1.
Further, described β base sodium sulfonate formaldehyde condensation products is made up of following weight ratio: NAPTHALENE FLAKES. (INDUSTRIAL GRADE） 0.2 ~ 1.0wt%, the vitriol oil 0.3 ~ 0.6wt%, formaldehyde 0.2 ~ 0.5wt%, liquid caustic soda 0.3 ~ 0.6wt%.
Further, described waterproofing agent of organosilicon is be the composite of octyltri-ethoxysilane and poly-Union carbide A-162, and ratio is 3.5:1.
Further, described concrete additive, the addition usually in concrete is only 0.5wt% ~ 2.5wt%.
beneficial effect
Additive provided by the invention, Comprehensive Preventing infiltration, shock resistance, rub resistance, diminishing, slow setting, the effect such as freeze proof, only need very little addition, concrete intensity and crocking resistance can be significantly improved, improve waterproof and workability, be enough to meet the requirement of the engineering such as airfield runway, bridge on highway to concrete property.
