Abstract
The invention discloses a retarding superplasticizer for roller-compacted concrete. The retarding superplasticizer is characterized by being prepared from the following raw materials in parts by weight: 60 to 80 parts of polycarboxylate superplasticizer, 10 to 15 parts of sodium lignin sulfonate, 2 to 3 parts of sodium hydrogen sulfite, 0.7 to 1 part of cellulose ether, 2 to 3 parts of calcium gluconate, 0.1 to 0.3 part of triethanolamine oleic soap, 2 to 3 parts of rosin-polythylene oxide ester, 0.7 to 1 part of 1,1-dichloroethane and 0.8 to 2 parts of tackifier. The retarding superplasticizer can be used for improving the workability of the roller-compacted concrete, and has the good water-retaining property and realizes bleeding reduction so as to improve the anti-frost property of the roller-compacted concrete. The retarding superplasticizer has a good effect for inhibiting an alkali-aggregate reaction, and is high in water-reducing rate, strong in VC (Vibrating Compaction) value retaining capacity and good in coagulation retarding effect. Thus, the retarding superplasticizer has the special applicability for the roller-compacted concrete.
Description
Technical field
The present invention relates generally to a kind of water reducer, relates in particular to a kind of efficient retarding and water reducing agent for roller compacted concrete.
Background technology
Water reducer refers under concrete workability and cement consumption permanence condition, can reduce mixing water amount, improve concrete strength; Or under workability and intensity permanence condition, save the admixture of cement consumption.The very large shortcoming of existence that water reducer used has now, such as raw-material bad adaptability, retarding effect is bad, and therefore poor water retention property etc. are produced high performance water reducer and are necessary.
Summary of the invention
The object of the invention is just to provide a kind of efficient retarding and water reducing agent for roller compacted concrete.
The present invention is achieved by the following technical solutions:
For an efficient retarding and water reducing agent for roller compacted concrete, it is mixed and to be formed by the raw material of following weight parts:
High performance water reducing agent of polyocarboxy acid 60-80, sodium lignosulfonate 10-15, sodium bisulfite 2-3, ether of cellulose 0.7-1, calglucon 2-3, trihydroxy ethylamine oleate soap 0.1-0.3, sylvic acid polyoxyethylene ester 2-3,1,1-ethylene dichloride 0.7-1, tackifier 0.8-2;
Described tackifier are to be made by the raw material of following weight parts:
Styrene-butadiene latex tackiness agent 20-30, nano-sized carbon 2-3, jade powder 1-2, wilkinite 2-3, rosin 3-5, Oil of Eucalyptus 1-2, tetramethylolmethane 2-3;
Above-mentioned tetramethylolmethane is heated to 160-165 ℃, add jade powder, wilkinite, 400-600 rev/min of dispersed with stirring 10-14 minute, adds nano-sized carbon, ball milling 3-5 minute, to after rosin heating fusing, add, fully mix, finally add styrene-butadiene latex tackiness agent, fully ball milling, cooling, obtain described tackifier.
Advantage of the present invention is:
Water reducer of the present invention can improve roller compacted concrete workability, and good water-retaining property reduces bleeding, the effect that has improved concrete antifreezing performance, water reducer of the present invention has good inhibition to alkali-aggregate reaction, and water-reducing rate is high, VC value hold facility is strong, and retarding effect is good.Roller compacted concrete is had to special suitability.

Performance test:
Water-reducing rate: 26.7%;
Bleeding rate: 45%;
Air content: 2.4%;
Time of coagulation is poor :+460min.
Volume of the present invention is the 1-2% of cement consumption, and in identical water cement ratio situation, more than can making concrete slump raising 15cm, mobility increases considerably.
