Adomast Adoflow Extra Super Plasticiser for Concrete – 25 Litre

Adomast Adoflow Extra 25 Litre is a liquid plasticiser and water reducing agent that imparts extremely high workability when added to a concrete mix.

Being a highly effective deflocculating agent. it disperses cement paste into its primary particles, significantly increasing the flow characteristics of the paste.

This permits significant reduction in water content of normal workability concrete producing higher early and ultimate strengths.

Adoflow Extra also enables the concrete to achieve high compaction with minimal or no tamping and its increased flow assists with difficult pours.

This variant is supplied as a 25 litre unit.

Advantages:

• Enables concrete to achieve high compaction with minimal or no vibration or tamping.
• Increases flow characteristics of concrete to assist with difficult pours.
• Permits significant reduction in water content of normal workability concrete with consequent reduction in water/cement ratio to produce higher early and ultimate strengths.

Yield:

1 Litre of Adomast Adoflow Extra 25 Litre per 100Kg of Portland Cement is a recommended starting point. Trials should be carried out to optimise the dosage for each concrete formulation.

Application:

The optimum addition rate of ADOFLOW EXTRA is best determined after preliminary trials with the actual concrete under consideration. As a guide for carrying out trials an addition rate of 0.5 litres to 1.5 litres per 100 kilos of Portland cement is recommended. Where high early and ultimate strength concrete is required, necessitating a steep reduction in water/cement ratio, the addition rate of ADOFLOW EXTRA may be increased up to 2.0 litres per 100 kilos Portland cement.

Mixing: ADOFLOW EXTRA is best added during the mixing cycle preferably at the same time as the water. Alternatively it may be added to a normal concrete mix just prior to the pour allowing for a further mixing cycle of at least 2 minutes
