FARCOPLAST M20

Applications

FARCOPLAST M20 can be used to reduce water-cementitious ratio to achieve higher strength required for:

• High rise commercial buildings.
• Pre-stressed beams and slabs.
• Precast elements.

FARCOPLAST M20 can be used to achieve flowing concrete without increasing the amount of water added to the mix; flowing concrete is suitable on projects:

• With tight spacing between steel reinforcement and pre-stressing tendons.
• Areas of congested reinforcing steel.
• Architectural concrete.
• Flat work and foundations where it can improve the rate of placement.

FARCOPLAST M20 can be used to achieve high slump concrete with lower W/CM ratio than normal concrete like:

• Structural elements that are either thin or congested with steel.
• Precast concretes which have architectural details and concrete must also gain strength at early ages.

Advantages

• FARCOPLAST M20 improves the rheological and mechanical properties of concrete; i.e. workability, compressive and flexural strength and modulus of elasticity.
• Can produce lower product costs with the superplsticizer to job site condition including faster and easier placement, enhanced finish ability and reduced curing costs.
• Reduced discharge and turnaround time for trucks
• Faster reuse of forms
• Improves impermeability to reduce sulfate attack
• Increase strength at all ages

Method of Use

• FARCOPLAST M20 is supplied ready for use and is completely miscible in water.
• It can be added in to the mixer at the same time as the mixing water.
• It should not be added directly to the cement or dry materials.
• FARCOPLAST M20 may be added at the end of mixing process by dispensing equipment or it may also be added to the concrete in a drum of ready mix truck, it should be mixed at least 1 minute per m³ of concrete at high speed.

Dosage FARCOPLAST M20

is normally dosed at a rate of 500-2500 g per 100 kg of cementitious materials (0.5%-2.5% by weight of CM). Field testing is recommended to determine the optimum dosage and effect on both plastic and hardened concrete properties such as: workability and workability retention, setting time, early and ultimate strength
