Abstract
The present invention belongs to the field of concrete admixture technology, and aims at providing modifier for concrete water reducing agent with low cost and can raising water reducing rate of concrete water reducing agent. The modifier for lignin sulfonate as concrete water reducing agent consists of triethanolamine 50-95 wt%, sodium lauryl sulfate 4-50 wt% and defoaming agent 0.05-2 wt%. Test shows that the adding the modifier in 0.2-1.5 % to lignin sulfonate concrete water reducing agent can raise the water reducing rate by 12-15 %, and may be used to compound pumping agent with high efficiency water reducing agent for replacing high efficiency water reducing agent in the equal amount within 15 %.
Description
Technical field:
The present invention relates to the properties-correcting agent of a kind of concrete admixture, particularly a kind of lignin sulfonate as concrete water reducing agent.
Background technology:
The water-reducing rate of cement water reducing agent is an important techniques index.Requirement according to GB GB8076-1997: coventional type cement water reducing agent water-reducing rate first grade is not less than 8%, and salable product are not less than 5%.And heavy duty detergent cement water reducing agent first grade is not less than 12%, and salable product are not less than 10%.From the eighties, the waste water that China promptly successfully produces papermaking is developed into the sulfonated lignin water reducer and is applied in architectural.Do paper making raw material with timber, its paper pulp wastewater can be made into calcium lignin sulphonate, is called for short wooden calcium.Do paper making raw material with non-timber, as reed, bamboo, bagasse, straw etc., its paper pulp wastewater can produce sodium lignosulfonate and magnesium lignosulfonate, is called for short wooden sodium and wooden magnesium.The wooden sodium that home-made wood calcium, wooden sodium, wooden magnesium and Russian Karma slurry factory produce, the water-reducing rate of these four kinds of water reducers is all between 8-9%.Therefore, belong to the coventional type cement water reducing agent.As naphthalene system and anthracene series high-efficiency water-reducing agent that concrete pump-feed agent adopted,, therefore, strengthened building cost undoubtedly at present because its price is more expensive.
Summary of the invention:
Technical problem to be solved by this invention is: the properties-correcting agent that a kind of lignin sulfonate as concrete water reducing agent is provided, it not only can improve the water-reducing rate of coventional type water reducer, the coventional type water reducer is used as high efficiency water reducing agent, and can also equivalent replace the high efficiency water reducing agent consumption in the concrete pump-feed agent.Its technical scheme is: a kind of properties-correcting agent of lignin sulfonate as concrete water reducing agent is characterized in that: it is to be made by the weight percent of following raw material:
Trolamine 50-95 sodium lauryl sulfate 4-50 defoamer 0.05-2.
Above-mentioned three kinds of raw materials are mixed, promptly get the properties-correcting agent of this water reducer.
Its technique effect is:
Show through experiment test: in the pulvis of above-mentioned sulfonated lignin (referring to the wooden sodium that home-made wood calcium, wooden sodium, wooden magnesium and Russia produce) water reducer, after mixing the properties-correcting agent of the present invention of 0.2-1.5% of its amount, its water-reducing rate can be brought up to 12-15% by the 8-9% that does not originally add properties-correcting agent, reaches the standard-required (ask for an interview table 1-sulfonated lignin coventional type water reducer and add the forward and backward water-reducing rate synopsis of properties-correcting agent of the present invention) of GB heavy duty detergent water reducer.

The aqua of the water reducer 1% in the above-mentioned table 1 is meant that the water of 0.25%+0.75% of pulvis water reducer is formulated.
Cement in the above-mentioned table 1 is P.O42.5 level ordinary Portland cement.
Simultaneously, also show after testing: after in above-mentioned sulfonated lignin ordinary water-reducing agent, mixing its properties-correcting agent of the present invention, itself and naphthalene system and anthracene series high-efficiency water-reducing agent are mixed with pumping agent, can equivalent replace high efficiency water reducing agent 15% (ask for an interview table 2-by the pumping agent of naphthalene system and the preparation of anthracene series high-efficiency water-reducing agent with replace naphthalene and be and the contrast table of the pumping agent that anthracene series high-efficiency water-reducing agent consumption is prepared by adding sulfonated lignin water reducer equivalent behind the properties-correcting agent)
