Product Description:

Polycarboxylate superplasticizer water reduce agent


HL-800 is a new type of polycarboxylate superplasticizer which has a high water reducing rate. As the third generation of water reducers, it is very effective in producing concretes with different levels of workability including applications that require the use of self-consolidating concrete(SCC). It complies with ASTM C 494 requirements for Type F, high-range water-reducing admixtures.


HL-800 is suitable for ready-mixed, pumping, hot weather concrete and the precast elements used in the construction which requires good workability and high early and final strengths. It can be applied in the preparation of various concrete of C40 and above grade with low water/cement ratio. When applied in preparation of concrete of higher than C80, it is recommended to conduct tests before bulk production.

Features and Benefits

1.       Excellent compatibility with various types of cements.

2.       High water reducing rate, low dosage, and low slump loss.

3.       Low chloride and alkali content, no corrosion to steel-bar

4.       High stability: no precipitation at low temperature.

5.       Environmental friendly and nontoxic


This product recommended content is 0.25% -0.85% of the total weight of cementitious

material, actually content should be experimentally determined.



1. HL-800 is always diluted to 10% to 20% concentration for use.

For example, to make 1 ton of HL-800 solution(10%), please fully dilute 200kg of HL-800 (50%) into 800kg of water.

2. When the weather is hot, making concrete with HL-800, a certain amount of retarding agent and air-entraining agent need to be added in the HL-800 solution (10%). On special occasions when slump loss of concrete speeds up and segregation appears after casting, it's necessary to add plastic retaining agent (or add our product of SR-1). Here's the general formula to compound HL-800.

HL-800 solution (10%):      980kg

Retarding Agent:           15-20kg

Air-entraining Agent:        2kg

The dosage of the finished product is 2.0-3.0% by weight of cement.

Packaging, transport and storage

1.It is packed in Flexitank in 20ft container, 220kg plastic drums or 1000Liter per IBC Tank, Other special package can also be available according to prior consultation.

2.Special measures should be taken to ensure entire package. Keep waterproof during transportation.

3.Dry and well ventilated warehouse is needed for storage. Quality guarantee of Polycarboxylate Superplasticizer is 12 months under normal conditions. If storage has surpassed the time, test must be done to confirm the validity.
