High range water reducer

Polycarboxylate superplasticizer

High range water reducing type(HL-800)

Description

PC super-plasticizer is an innovative new generation polycarboxylate ether based slump retaining aid with super 

retention technology. Additionally, it can help the ready-mixed, precast concrete industries, where more than normal

slump retention and durability are required. PC super-plasticizer is a specifically tailored, stand alone product, the

constituents of its active ingredient exhibiting unique adsorption characteristics to cement. 

PC super-plasticizer can be used in conjunction with modified lignosulphonate based admixtures only to aid in super slump retention of a concrete mix. The excellent dispersion effect makes it the ideal aid for the ready-mixed concrete, precast concrete industry, without affecting concrete setting times. The ability to work over a range of water binder ratios including low w/b ratios and still obtain extended slump retention allows for the manufacture of high quality concrete.

Application

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.

Properties

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

Dosage

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

material, actually content should be experimentally determined.

Usage

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.
