Polycarboxylate superplasticizer with 50% solid content

Description

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). 

Application

polycarboxylate superplasticizers for pre mix concrete, which is the home and 

abroad latest  polycarboxylic type acid Sulfonate of high performance water 

reducing agent ,contain the Poly ethoxy side groups.

Comparing with the common high performance water reducer,it has the characteristic of High water reducing rate, low dosage,  good adaptability to cement, making net slurr good liquidity used in concrete, little slump loss, save the cement consumption , no pollutio and so on, as well it can improve the fresh concrete performance index and improve the workability

it is applicable to all kinds of  pumping concrete, mass concrete, viaduct, highway, bridge, hydraulic

concrete, especially key projects and the concrete with special requirements.After being diluted and 

compounded, it can be used in the concrete mixing plant.

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.
