Superplasticizer Solutions of Precast and Pile Concrete

Item No:KZJpoint RA8206

It is made from our KZJpoint 811A(High early Strength PCE)Material which is designed for autoclave-free high-strength pipe pile concrete, precast concrete and prestress concrete. It complies with GB 8076 and ASTM C494 Type E.


Item No:KZJnazem RS86

The traditional Naphthalene-based superplasticizer with steam curing treatment for pile concrete.

Normally and traditionally, pipe pile company will choose naphthalene-based superplasticizer firstly as the Naphthalene-based superplasticizer has been developed in the last century and the technology of it has been used all around the world. Nowadays, with the applications of polycarboxylate superplasticizer in pipe pile company successfully, Polycarboxylate superplasticizer has been popular in China recently. Since there is limited precedent for mass production in overseas market with PCE products, KZJ China would like to be the pacemaker of technical promoting the high early strength polycarboxylate Superplasticizer under steam curing or Non-autoclaved curing by the different formula in the KZJpoint RA8206. Our rich experience of R&D in PCE and concrete technology from our many customers of pipe piles companies in the last five years, such as TianHai Pipe Pile company group and Beiwant Pipe Piles concrete, would benefit our overseas customers of pipe pile companies.

The Advantages of KZJpoint RA8206

High Water Reducing Ratio

The water-reducting mechanism and principle of polycarboxylate superplasticizer are different from naphthalene-based superplasticizer. When it is used on pipe piles, the viscosity of concrete becomes significantly great with more than 500kg cementitious materials/m3,and the heavy viscosity can be improved with by the KZJpoint RA8206. On the other hand, the special mould process of the pipe pile makes the proper increase of the water-cement ratio not adversely affect its strength.

Pile Concrete with KZJpoint RA8206 under steam curing with temperature of 60~80 degree can reach 70%~80% of the designed strength in 12hrs, If It is under natural curing (non-Auto claved), the strength develops to 60~70% of designed strength in 12hrs and 100% of the designed strength in 3 days which meets the standard requirement of GB13476.

Good Adaptability and Plasticity

KZJpoint RA8206 has better adaptability to various cement, fly ash, slag, silica fume, and the initial slump of 50-90mm will be achieved easily, which meets the requirements of feeding pouring and centrifugal molding process.

Pile Concrete Technical Problems KZJ have solved by KZJpoint RA8206

1.The heavy viscosity of pile concrete;
2.Sensitivity in production: the change of sand moisture content, the fluctuation of slump adjustment is relatively great;
3.The slump loss problem of carboxylic acid in production:
It is mixed with fine sand, and its adsorption is relatively large, which leads to the reduction of effective ingredients and the slump retention ability is also greatly affected.

Application of High Early Strength Polycarboxylate Superplasticizer in Beiwang Pipe Pile Concrete

With the unremitting efforts of the technicians in Beiwang pipe pile, we successfully solved problems of the setting time, static stop process, less residual slurry and excessive stickiness of the pipe pile concrete produced by using polycarboxylate superplasticizer and other issues. Beiwang pipe pile has been using KZJpoint RA8206 for more than 3 years and the production condition is good.

1. KZJpoint RA8206 polycarboxylate superplasticizer for pipe piles concrete can be properly compounded with air-entraining agent to control concrete air content to be 2.5%~4.0%, which can reduce the viscosity of the concrete without adversely affecting the concrete strength.
2. KZJpoint RA8206 will not adversely affect the slump loss, setting time, strength and brittleness of the pipe pile concrete.
