Poly 55

GEO CHEMICAL - POLY 55

High Range Water Reducer/ Super Plasticizer Concrete Admixtures

High performance permeability and Anti freeze (Accelerator) admixture  

 

Description

GEO CHEMICAL POLY 55 admixture are Super plasticizers formulated that are based on Polynafthalene Sulphonate This product from selected polymers specially designed to enable the water content of the concrete perform more effectively with higher developed early strength, this effect can be used to improve workability, to increase ultimate strengths or to facilitate a reduction in the cement content while sustaining mix properties.

POLY 55 gives high slump increase with the same amount of water.

 

Application

Poly55 admixture is used in condition such as:

# High strength concrete.

# Low water cement ratios.

# To produce high quality concrete of improved durability and water tightness.

# In slab and foundation, precast, curtain walls, girders, and columns, in bridges, in architectural structures and in RCC concretes.

# To concrete elements with thin and dense reinforcements.

# To cold and warm weather.

# To pre stressed construction blocks.

# For application where fast stripping needed.

 

 Advantage

# Improved workability without increase water content.

# High reduction in water without loss of workability.

# Improved early and long term strengths.

# Gives smooth surface after leveling.

# It is more suitable to be used in reinforced concrete constructions.

# Increases the resistance of the concrete against water and frost.

 

Standards

# BS EN 934-2 Chart 3.1 and 3.2 : High Range Water Reducer/ Superpalasticizer Concrete Admixtures .

# BS EN 934-2 Chart 11.1 and 11.2 : Set Retarder /High Range Water Reducer/ superplasticizer Concrete Admixtures.

 

Package

Poly is available in 200 liter barrel, 1000 liter bulks supply, tanker.

 

 

Dosage

Poly 55 admixture are depending on performance expected from the concrete, it is between

(% 0.9- 1.5) of the binding material (cement, micro silica, fly ash) amount.

If dosed over % 1.5 in winter months, set retarding may be observed, in order to find optimum admixture dosage, it is recommended to make experimental and aggregate used.

when it is required, GEO CHEMICAL Construction Chemicals Technical Support Unit should be consulted.

Compatibility

Poly 55 admixture is compatible with other GEO CHEMICAL admixtures used in the same concrete mix, if more than one type of admixture will be used in the concrete mix, they must be dispensed to the concrete separately.

Cleaning 

Poly55 admixture spillage should be collected by a suitable absorbent such as vermiculite and transferred by suitable container, and should not be allowed to enter sewers or open bodies of water, dispose of in accordance with local environmental regulations.

Storing Condition

It is store in dry condition, Poly 55series has minimum shelf life of 12 months from date of manufacture if stored properly in its original unopened packing.

If the additive is frosted under +5 c it should be thawed by waiting at ambient temperature without  using direct heating and mixed until it becomes homogeneous.

Compressed air should not be used during this operation.
