Abstract

A high performance concrete water reducing agent is prepared from the following raw materials by weight: 20-30 parts of poly carboxylic acid mother liquor, 1.5-3 parts of sodium gluconate, 0.1-0.3 part of an air entraining agent, 0.1-0.3 part of maltodextrin and 70-80 part of water. The high performance concrete water reducing agent can greatly improve the fluidity of concrete, the concrete can keep the construction performance for long time, and the high performance concrete water reducing agent can improve the concrete workability and physical mechanical performance, and improve the project quality.

Description

High performance concrete water reducer
Technical field:
The invention belongs to a kind of material of construction, particularly a kind of high performance concrete water reducer.
Background technology:
The superiority of high performance concrete is not singly that intensity is high, and this structured material of what is more important has following a series of corresponding excellent properties: 1, intensity is high, even if only need shorter curing age in the winter time, ensure that engineering progress speed yet.2, there is long-term weather resistance.3, resistance to chemical corrosion is strong, can be used in various special engineering.4, it possesses serviceability excellence, easily pumping, the easily excellent workability such as closely knit on high water reducing rate, high strength basis simultaneously.At present, in the technical measures preparing high performance concrete, key is reasonable employment high-performance chemical admixture, especially has the high-performance water reducing agent that efficient diminishing, suitably bleed also can reduce and prevent Slump Time losing of Large.
Summary of the invention:
Object of the present invention is just to provide a kind of high performance concrete water reducer, this product can improve concrete mobility greatly, make the concrete energy long period keep workability, can concrete workability and physical and mechanical property be improved simultaneously, improve construction quality.
As above conceive, technical scheme of the present invention is: a kind of high performance concrete water reducer, is characterized in that: be made up according to following weight proportion of following raw materials according: poly carboxylic acid mother liquor 20-30 part, Sunmorl N 60S 1.5-3 part, air entrapment agent 0.1-0.3 part, Star Dri 5 0.1-0.3 part and water 70-80 part.
The solid content of above-mentioned poly carboxylic acid mother liquor is 40%.
The solid content of above-mentioned Sunmorl N 60S is 99%.
The present invention has following advantage and positively effect:
1, good with the consistency of various cement, concrete slump retention performance is good, can extend the concrete engineering time.The leading indicators such as water-reducing rate, slump retention value, cement and admixture adaptability all reach the technical requirements of GB8076-2008 " concrete admixture ".
2, volume is low, water-reducing rate is high, shrinks little.
3, concrete early stage, later strength can be increased substantially; Chloride ion content is low, alkali content is low, is conducive to concrete weather resistance.
4, production process is pollution-free, and not containing formaldehyde, meeting ISO14000 Environmental protection management international standard, is the features such as a kind of Green Product.
5, the prefabricated and onsite concrete of the engineering constructions such as high-speed railway, Line for Passenger Transportation, industry and covil construction, road, bridge, port and pier, airport, Steel Concrete and prestressed concrete is applicable to.
Embodiment:
Embodiment 1: a kind of high performance concrete water reducer, is made up according to following weight proportion of following raw materials according: poly carboxylic acid mother liquor 20Kg, Sunmorl N 60S 1.5Kg, liquid air entrapment agent 0.1Kg, solid Star Dri 5 0.1Kg and water 70Kg.The solid content of above-mentioned poly carboxylic acid mother liquor is 40%.The solid content of above-mentioned Sunmorl N 60S is 99%.
Embodiment 2: a kind of high performance concrete water reducer, is made up according to following weight proportion of following raw materials according: poly carboxylic acid mother liquor 30Kg, Sunmorl N 60S 3Kg, liquid air entrapment agent 0.3Kg, solid Star Dri 5 0.3Kg and water 80Kg.The solid content of above-mentioned poly carboxylic acid mother liquor is 40%.The solid content of above-mentioned Sunmorl N 60S is 99%.
The consistency of the present invention and various cement is good, and the leading indicators such as concrete slump retention performance is good, water-reducing rate, slump retention value, cement and admixture adaptability all reach the technical requirements of GB8076-2008 " concrete admixture ".
