DESCRIPTION: OASIS PVA BOND is a resin based plasticized adhesive for the construction industry as a bonding additive to concrete and plaster. Upon drying it forms a thin film which is non-discoloring to the surface.

USES:

• For concrete repairing.
• As an admixture to the mortar to give great adhesion to the plasters.
• As a primer for over coating.

ADVANTAGES:

• Alkali resistant.
• Can be applied to damp surfaces, with out puddles or brittleness.
• Once occurred, it is flexible and remains unaffected to climatic and weather conditions.
• Work on traction and shearing.

APPLICATION:

• As a Concrete Admixture: OASIS PVA BOND is added at the rate 25 -35 litres per 100kg. of cement.
• For Domestic: Use 3 part of sharp sand, 1 part of cement and 30 litres of OASIS PVA BOND per 100Kg.
• As a Bonding Coat: Use undiluted - 1 part of OASIS PVA BOND with 2 part of water.
• As a Primer Coat: Use undiluted 1 part of OASIS PVA BOND with 1 part of water.

STORAGE:

OASIS PVA BOND should be stored in a covered, dry place avoiding exposure to heavy sunlight. Under normal ambient condition the product has a shelf life of 2 3 months.

PACKING:

OASIS PVA BOND is available in 200 kgs metal drums.

DESCRIPTION:

OASIS WRDA P8 is an accelerating plasticizer or water reducing agent for concrete and mortar. OASIS WRDA P8 is based on calcium chloride particularly useful for obtaining high strength in precast items such as blocks and lintels. OASIS WRDA P8 is completely soluble in the calcium chloride solution and no separation can occur even at low temperature.

OASIS WRDA P8 is formulated from carefully selected raw materials and is manufactured under controlled conditions to yield a consistent product. It is based on naturally derived materials dissolved in calcium chloride solutions.

ADVANTAGES:

• OASIS WRDA P8 imparts ultimate strength to concrete enabling fast adhesion.
• The effect of plasticizing action of OASIS WRDA P8 will give increase workability to most concrete mixes enabling easier placing.
• Water reductions of 10% in the region can be made without adversely affecting the workability with a subsequent increase in strength, impermeability and durability.
• OASIS WRDA P8 offers an improvement over most other accelerating plasticizers with its fully compatible system which will not seed out at low temperatures, which can lead to blockages of pipe lines and inconsistent results.

TYPICAL PROPERTIES:

Appearance: Pale YellowLiquid Specific Gravity: 1.34 at 20C Air Entertainment: There is a possibility of slight air entertainment which rarely exceed 0.7%.Chloride Content: 34% approximately.Freezing Point: 7C SHELF LIFE: Shelf life is 12 months in unopened condition.

COMPATIBILITY:

• Compatible with all types of Portland cements.
• Should not be mixed with other admixtures. The performance of the material may be affected by the presence of other chemicals.

METHOD OF USE:

OASIS WRDA P8 is supplied ready for use. It should be added to the concrete mix at the same time when water is added. It should not be added directly to the cement. No extension of normal mixing time is necessary.

NOTE:The performance of OASIS WRDAP8 is best assessed after preliminary tests on site using the actual concrete under consideration to determine the optimum dosage and the effect on properties such as ultimate compressive strength, early rates of strength and shrinkage.

As a guide to these trials, an additional rate of 1680ml 3360ml of OASIS WRDA P8 per 100Kg cement is recommended.

WARNING:

Under no circumstance, should additions be made at a higher level than the maximum dosage of 3360ml OASIS WRDA P8 per 100kg cement, due to possible deleterious effects of excessive calcium chloride.

EFFECTS OF OVERDOSING:

Overdosing of OASIS WRDA P8 will generally produce a considerable increase in workability and will shorten the setting and hardening process. Such over dosing is however, to be avoided because the maximum addition rate of OASIS WRDA P8 is equivalent to approximately 1.4% by weight of anhydrous calcium chloride based on the cement.

This is the level normally advised as being the maximum that should be used in cementitious compositions.

PRE-STRESSED and POST TENSIONED CONCRETE:

OASIS WRDA P8 contains calcium chloride and should not under any circumstances be employed in concrete when pre-stressing is done.

DISPENSING:

It is preferable that liquid admixtures for concrete should be introduced into a mixer by means of automatic dispensing equipment, details of which are available upon request.

PACKAGING:

OASIS WRDA P8 is supplied in nominal 200 litre drum. Alternatively bulk deliveries can be arranged.

STORAGE:

OASIS WRDA P8 should be stored in sealed conventional containers.
