JS 700 microsilica super gel

Super Gel JS 700 Make of high-strength and impermeable concrete, with high tensile and compressive strength with early resistance

Description :

JS 700 is a carboxylate-based additive with pozzolanic properties and increases the rheological properties of concrete in the form of a paste to make concrete with high compressive and flexural strength. The mechanism of action of this product is the reaction with the released calcium hydroxide due to hydration of cement. The product made in concrete composition is beneficial, reduces the permeability of concrete, increases its durability and stability. This product is also produced in fast (JS700 A) and late (JS700 R) fiber (JS700 F) codes.

Properties and effects:

• Reduce the ratio of water to cement
• Reduction of cement consumption between 15 to 20%
• Increase the fluidity and efficiency of concrete
• Increased compaction and thus durability of concrete
• Increase the compressive strength of concrete between 20 to 60%
• Increased tensile strength and impermeability of concrete
• Increase the resistance of concrete against the melting and freezing cycle
• Increased resistance in alkaline environments
• Increasing the chemical resistance of concrete against harmful ions of chlorine, nitrates and sulfates
• Easy pumpability and reduce machine depreciation

Application :

• Construction of various reservoirs, swimming pools, water and sewage canals, treatment plants and manholes
• Construction of offshore structures, piers, bridges and dams
• Increase the durability of concrete in bulk structures
• Construction of structures with high modulus of elasticity
• Manufacture of impermeable and high-strength concretes
• Construction of structures exposed to the attack of destructive chemical ions and corrosive substances

Complies with standards:

BS EN 12390-8 – BS EN 1881-122 – ASTM C1202 – ASTM C494

Consumption :

The optimal consumption of JS700 super gel is determined according to the tests at the concreting site and mixing plan (amount and type of cement, sand, sand, water and other materials) and air temperature and determined resistances. The recommended consumption dose is between 4 to 9% of the weight of cement used.

Method of Use :

1. To be added to the ready-mixed concrete in the mixer truck or when making concrete to batching.
2. It is mixed with part and all of water concrete and then added to concrete.

Mixing time and reaching the appropriate rheology varies according to the volume of cement. Mixing takes between 60 and 90 seconds per cubic meter.

No additives should be poured directly on cement or dry stone materials.

Maintenance :

It can be stored in the original packaging and in a covered warehouse away from direct sunlight at a temperature of 10-30 ° C for one year after the date of manufacture.

Package type:

25 kg bucket

safety tips :
