Batimix WR 102-S

Description

BATIMIX WR 102-S is a liquid water-reducing admixture for concrete. It is based on high-grade lignosulphonate materials blended with selected chemicals to improve slump retention over time.

Main Purpose

BATIMIX WR 102-S is designed to improve concrete workability and/or allow an effective reduction in the free water content. It disperses the fine cementitious particles in the concrete mix, enabling the mixing water to perform more effectively and improve the concrete consistency.

BATIMIX WR 102-S is particularly suitable for use in hot weather conditions where a delayed set will provide sufficient time for delivery, placement, and finishing operations. Applications include all types of concrete castings such as plain, reinforced, precast, ready-mixed, lightweight, and pumped.

Features

Concrete prepared with BATIMIX WR 102-S is characterized by the following:

In the plastic state:

• Improved workability without adding extra water
• Reduced water content up to 15% with minimum secondary effects
• Increased homogeneity with minimum segregation and bleeding
• Better slump retention over time, relevant for hot weather concreting

In the hardened state:

• Increased strengths – compressive, flexural, and bonding
• Reduced shrinkage, creep, and water- permeability
• Enhanced concrete durability and surface- appearance

Properties

• Appearance: brown liquid
• Specific gravity: 1.14 ± 0.02 at 23 ºC
• Chloride content: nil
• Alkali content: typically less than 4.5% as Na₂O
• Air entrainment: less than 1.5% increase at normal dosages

Health and Safety

BATIMIX WR 102-S is not a hazardous material. However, it should not be swallowed or allowed to come into contact with skin and eyes. Suitable gloves and goggles should be worn. For additional information, kindly refer to the product’s Material Safety Data Sheet.

Compliance with Standards

BATIMIX WR 102-S is compliant with the following standards:

• EN 934-2 : T10 • ASTM C 494 Type D

Dosage Rates

The optimum dosage of BATIMIX WR 102-S to meet specific requirements is best determined by trials using the actual concrete formulation with site materials under conditions that will be experienced in the field. As a guide to such trials, the addition rates shall vary from 0.2% to 1.4% of the cementitious materials.

Effect of Overdosing

An overdose of BATIMIX WR 102-S will generally produce an increase in the slump and, in certain circumstances, a significant increase in air entrainment. Retardation in the initial and final setting times will also be noticed. However, if the concrete is properly cured, the ultimate strength will not be impaired by such setting retardation.

Compatibility

BATIMIX WR 102-S is compatible with all other Batimix admixtures incorporated in the same concrete. During batching, all admixtures should be dispensed and added separately to the concrete mix. The performance of various admixtures should be assessed using trial tests as such combinations may alter setting times, air entrainment, and early strength gain.

BATIMIX WR 102-S is compatible with all types of Portland cement and replacement materials such as silica fume, fly ash, and blast furnace slag.

Dispensing

Automatic dispensing systems should preferably be used to introduce the correct quantity of BATIMIX WR 102-S in the concrete mixer. This admixture should not be directly added on the dry cement. It should rather be introduced after incorporating around 2/3 of the mixing water to enhance its effectiveness and improve its dispersing properties.

Technical Support

For proper products usage, Holderchem provides complete technical and laboratory support as well as on-site assistance pertaining to concrete mix design, admixture selection, materials testing, and dispensing equipment.

Storage

BATIMIX WR 102-S has a minimum shelf life of 12 months if kept unopened and stored at temperatures ranging from 2 to 50 ºC.
