Poly 77
GEO CHEMICAL POLY 77
High Range Water Reducer/ Super Plasticizer Concrete Admixtures
High performance permeability and Improved workability, compaction problem.
GEO CHEMICAL POLY 77 admixture are Super plasticizers formulated that are based on Polynafthalene Sulphonate This product from selected polymer s specially designed to enable the water content of the concrete perform more effectively with higher developed early strength ,this effect can be used to high strengths, improve segregation and bleeding problem, compaction problem with , workability, to increase ultimate strengths or to facilitate a reduction in the cement content while sustaining mix properties, POLY 77 gives high slump increase with the same amount of water .
Application
Poly77 admixture is used in condition such as:
- High strength concrete.
- Low water cement ratios.
- Improved cohesion allows for use in mass concrete pours and pilling .
- 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 pre cast concrete .
- To pre stressed construction blocks .
- For application where fast stripping needed.
Advantage
- Improved workability with out increase water content. reduce placing &compaction.
- High reduction in water with out loss of workability.
- Improved early and long term strengths, cement saving with out affecting strength.
- Gives smooth surface after leveling ,reducing segregation& bleeding problem.
- It is more suitable to be used in reinforced concrete constructions,
- Increases the resistance of the concrete against water and frost

Package
Poly is available in 20 liter pails, 200 liter barrel, 1000 liter bulks supply, tanker.
Dosage
Poly 77 admixture are depending on performance expected from the concrete, it is between %0.9- 1.8 of the binding material (cement, micro silica, fly ash) amount. if dosed over %1.9 in winter months , set retarding may be observed & increase workability with mixing cementitiousematerial ,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 77 admixture can be used with all type of portland cement and cement replacement material, that is compatible with other GEO CHEMICALE 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
Poly 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 77 series ha 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.
