Polycarboxylate Superplasticizer Water Reducer Concrete Admixture

Product Description

Polycarboxylate superplasticizer concrete water reducer 98% powder

1,concrete water reducer Introduction:

polycarboxylate superplasticizer is a new type of water-reducing agent. The utilization of this product can improve the slump retention performance of the concrete, ensuring a barely no loss within half an hour and a small loss within 1 hour. This product also plays a good role in reducing cement additive amount, improving water reducing efficiency and dropping shrinkage rate. Using this product can validly boost concrete flowability so to extend the setting time during construction. What's more, it can promote the workability and physical properties of the concrete, which is important for construction quality.

2,concrete water reducer Main Performance:

(1)Visual appearance: white powder

(2)Cement Paste Performace

3,concrete water reducer Recommed Dosage:

The recommend dosage of superplasticizer for concrete: 0.1-0.25% base on cement quantity.

Solid contents of PCE powder is 98%. Normal dosage is 0.12%-0.3%. when dosage is 0.06%, it

has 12% water reducing rate and 23% strength growth, this beyond the performance of common pumping agent in market. when dosage is 0.1%, performance beyond that of PNS and Melamine. But when dosage is below 0.14%, its good performance is not obvious. When dosage is above 0.20%, it is excellent in concrete fluidity and pumping performance. Therefore, the best dosage is recommended as 0.12-0.24%; when making concrete with high grade, big dosage of flyash or superfine slag powder or other special requirements, dosage can be expanded to 0.3-0.5%. Test state that there is no cohesion and bleeding in concrete even the dosage expand to 0.5%, and its water-reducing rate still increase . But air content increase, setting delay, strength decrease.

4,concrete water reducer Technological Characteristics:

At present, most PCE powder in market are produced by process of sparying and drying. So they

have some defect: its 5% separant,3% moisture result loss of effective constituent and performance in use.

We break the routine of producing PCE powder. It First use the technology of thermosynthesis which save the producing cost in a lot, without separant, with high purity of 98% solid contents. In performance, high purity guarantee the low dosage, more effective constituent guarantee the better slump retention, those save the cost for client.

5.concrete water reducer Use Method

(1)According to the design of concrete, adjust quantity the water or sand to make sure the slumps,

strength, setting all to meet with requirements base on the required dosage of admixture.

(2)It apply to concrete with high performance ,strength and fluidity. When make C50 concrete,

it should choose the suitable material according to relative technology rule and confirm the

suitable mixing technology base on enough test data. To make sure the fluidity of concrete can

meet with the requirements of engineering, the strength of concrete should have surplus .

(3)This product can be added into concrete together with water which is used in mixing. but it

will get better performance if mix it with water firstly.

6,concrete water reducer Safety and Attention:

(1)This product is alkalescence solid without toxic, corrosiveness and pollution. It is unedible.

when it come to body and eye, please wash it in clean water. When there is allergy for some body,

please send the person to hospital rapidly for cure.

(2)This product is storaged in paper barrel with PE bag inner. Avoid rain and sundries to mix in.

(3)Quality guarantee period is 12 months

(4)Package: Paper-Plastic lamination package with PCE inner.
