INTEGRAL WATERPROOFING COMPOUND

Admixtures Chemical

Description

A liquid admixture for concrete to give high water resistance based upon a blend of surface-active agents and refined lingo-sulphonate. Waterproof concrete is the result of good concrete practice coupled with the lowest w/c ratio compatible with achieving full compaction. The use of SAVE- IT 101 enables all these criteria to be met due to its strong plasticising and water reducing properties.

Primary Uses

SAVE- IT 101 should be used in all structural concrete that is constantly or intermittently in contact with water such as sea walls, tunnels, basements, structural and pre-cast concrete in exposed superstructures.

Advantages

• Concrete containing SAVE- IT 101 is resistant to water penetration either under conditions of hydrostatic pressure or capillary absorption.

• Durability is increased due to a significant reduction in w/c ratio.

• The cohesive properties of the concrete are improved thus reducing segregation and bleeding.

• The use in cement mortar gives excellent water proofing qualities and it is recommended to use in cement mortar renderings in brick bat coba and box type treatment for stone fixing.

• The surface finish of the concrete is improved.

Standards

ASTM C494: Types A & D.

IS: 2645.1991

Directions for Use

SAVE- IT 101 should be added to the concrete mix/ cement mortar during the mixing cycle at the same time as the water and the aggregates. Never add SAVE- IT 101 to the dry cement.

Dosage

Field trials should be conducted to determine the optimum addition rates of SAVE- IT 101. A dosage range of 300ml to 600ml per 100kg cement is recommended as a starting point.

Effects of over dosage

A severe over-dosage of SAVE- IT 101 will result in the following:

• Retardation of initial set.

• Increase in air entrainment.

• Increase in workability.

Packaging

SAVE- IT 101 is available in 10, 25, 50, 100 & 200 ltr drums

Points to remember when producing waterproof concrete :

• Ensure specified water/cement ratio is not exceeded; work within the range of 0.4 to 0.5.

• Keep water content as low as possible compatible with achieving full compaction.

• Place concrete quickly and ensure it is thoroughly compacted.

Action

SAVE- IT 101 assists in the production of water resistant concrete by its two fold action:

1. It significantly reduces water demand to enable production of good workability concrete with a Minimum water/cement ratio.

2. It disrupts the cellular network within the concrete mass (capillaries) that are normally inter-connected thereby reducing the concrete permeability.

Storage

Store under cover, out of direct sunlight and protect from extremes of temperature. Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging.
