Detailed introduction:

NEXT-Generation Water Reducing agent

1.Polycarboxylate superplasticizer water reducing agent

2.Slow release polycarboxylate superplasticizer slump retention water reducing agent

2. Slow release Polycarboxylate superplasticizer slump retention water reducing agent

CL-BT-40 and CL-BT-50 Slow release polycarboxylate superplasticizer slump

retention water reducing agents are 2015 new R&D products by Binzhou

Chengli Building Materials CO.,LTD.

The Advantages:

1. New formula,fully reaction, pure appearance

2.Low dosage and high water reducing rato

(40% mother liquid) tested by Shanlv P.O.42.5 ordinary portland cement,

with the dosage of 0.4% of CL-BT-40

87g water+1.2g CL-BT-40+300g cement

Time slump variation retention
30min 240mm rising
60min 280mm max
120min 280mm max
180min 260mm lost

CL-BT-40 and CL-BT-50 have the more stronger effect on keeping slump retention than the other

slump retention water reducing agents of china.

If you met the same trouble ,please ask for a sample to test:

Some kinds of cement are terriblly bad . the normal slump water reducing agents may only can

effect in 30mins. later the cement will lost the pumping ability. but CL-BT-40 and CL-BT-50 can

last the pumping time to at least 60mins.

if need the method of making dilution mother liquid ,please send e-mails

to the sales.

3.CL-BT-40 and CL-BT-50 Slow release polycarboxylate superplasticizer

slump retention water reducing agents can totally take place the other

water reducing agents

polycarboxylate superplasticizer water reducing agents take 60% market

in china,30% market are taken by Aliphatic water reducing agent.

Materials fully chemical reaction → pure appearance→stable quality

China supplier construction material Specifications:
(1) Powder (with a solid content ≥92%, solid, suitable for a long distance transportation) , or liquid (with a solid content of 20%-50%).
(2) With a high slump retention ability, without concrete segregation, with a much smaller slump loss than that of other superplasticizers.
(3) With a good dispersion, an excellent adaptability to different cements, and good water-reducing properties. A high water-reducing ratio up to 40% could be obtained when used in high strength grade concrete.(higher than C50). With a dosage of 0.4%,water reducing rate up to 28%.
(4) Low chloride content, and no corrosion to steel.
(5) Cement paste fluidity ≥250mm (with a dosage of 0.5%).
Uses and Cautions:
(1) A recommended dosage is 0.25%-0.8%. Actual dosages should be determined by mixture design test according to concrete strength grade.
(2) It is required that the tolerance must be less than 1.0%.
(3) 0℃-40℃ the shelf life of liquid products is 6 months. After expiration date, concrete test must be carried out to confirm the quality.
(4) Concrete test must be carried out before utilization.
(5) This product is forbidden to be mixed with naphthalene superplasticizers.
(6) Experiment must be done when it is used together with other admixtures.
