Details

Tittle:
A Chinese company is looking for the technology of producing and applying functional polycarboxylate water reducing agent.
Summary:
A Chinese concrete admixture and polymer material company is looking for functional polycarboxylate water reducing agent.

They want to cooperate with partners through research cooperation and technical cooperation. They are willing to spend 15 million yuan on this technology.
Description:
This Chinese company was established in 1990.

It is a famous integrated joint-stock enterprise which devotes itself to the research, production, sell, application and consultation of concrete admixture and polymer material.

The company´s manufacturing technique is in the leading position of China. There are three synthetic producing lines of polycarboxylate water reducing agent, a liquid quick-setting agent synthesis line, two synthesis lines for admixtures, such as polycarboxylate water-reducing agent and waterproofing agent, and a powder line.

The enterprise has been identified by ISO 9001 Quality Management System and has passed China Railway Test.

The company is hoping to collaborate with partners for research cooperation and technical cooperation of functional polycarboxylate water reducing agent.

Some relevant matching technologies are to be studied according to the problems in the process of applying polycarboxylate water reducing agent to concrete engineering, such as anti-freeze in winter, loss of liquidity in summer, anti-rust agent and quick-setting agent.
Technical Specification or Expertise Sought:
1. High performance polycarboxylate water-reducing agent.
(1) Ultra high water-reducing A
It mainly fits for ultra-high strength concrete and clay stone powder containing high concrete. After ensuring that the initial concrete´s large mobility of full dispersion, its water reducing rate can reach 40% or higher under the condition of subtracting 0.2% water from dosage .
(2) High performance water reducing agent with good adaptability can be widely used in different projects´ concrete.

2. Slump-retaining polycarboxylate water-reducing agent
(1) Slump-retaining polycarboxylate water-reducing agent A has a good slump retention. Its rate of reducing water is relatively high. This product, as it remixes regular pumping agent, should make the slump of newly-mixed concrete remain unchanged over 1 and an half hour when the temperature is higher than 30¿ in summer or the content of raw dinas materaial and clay powder are relatively high.
(2) High slump-retaining polycarboxylate water-reducing agent B has a great slump retention. Its rate of reducing water is relatively low. This product, as it remixes regular pumping agent, should make the slump of newly-mixed concrete remain unchanged over 2 hours when the temperature is higher than 30¿in summer or the content of raw dinas material and clay powder are relatively high.

3.Anti-clay slump retaining agent
There is hardly water-reducing rate. It takes place of polycarboxylate water-reducing agent with 30% solid content or more, so that the concrete has a strong plasticizer. This agent, as it remixes regular pumping agent, should make the slump of newly-mixed concrete remain unchanged over 3 hours and no mobility loss when the temperature is higher than 30¿ in summer or the content of raw dinas material and clay powder are relatively high.

4.Early-strength polycarboxylate water-reducing agent
It is suitable for concrete under the condition of steam curing, such as subway segments. The strength of 1D can reach 85% of the design strength, and that of 3D reaches 100%. The strength of 28d is no less than the 28d strength of the standard poly carboxylic acid water reducing agent concrete, and it does not shrink .

5. As for steel bar corrosion in reinforced concrete in Offshore Oil Engineering, the preparation of ultra high performance concrete must be mixed with rust inhibitor. And the effect of inhibitor, which reaches national or industrial standards, on concrete´s workability, intensity, durability should be studied.

6.Quick-setting agent
They want to develop environmental-friendly quick-setting agent. The agent must meet the national and industrial standard and its appearance is stable without separated layers.

7.Thickening water retentive agent
It should improve concrete´s sticky, water conservative and slump retaining functions, and achieve the advanced level of similar foreign products.
