Description :

Concrete Accelerator Admixture K Crete Ae acts as the interface of the cement-aggregate particles and mixing water to produce microscopic air bubbles evenly distributed throughout the concrete. The entrained air bubbles are of the optimum Diameter and spacing to give durability under freeie-thaw or salt attack conditions whilst enhancing lubrication during placing.

K Crete Ae complies with IS-9103-1999, Increased durability. Improved workability, increase compaction whilst the controlled air entrainment considerably enhances resistance to attack by frost or salts by reduction of Initial surface absorption of hardened concrete.

Increase the resistance of concrete to damage by sea water, frost and de-icing salts and also makes concrete structures less prone to cracking. Reduces the permeability of low cement content for mass pours such as dams and breakwaters.

Is an ideal pumping aid to maintain coheslveness and minimize segregation where concrete is placed mechanically. Improves the quality and long term durability of concrete exposed to severe weathering conditions.


Advantages :

• Increases workability and cohesion
• Increased Cohesion : Entrained micro-bubbles of air assist in producing cohesion.
• Improves workability, increases compaction whilst the controlled air entrainment considerably enhances resistance to attack by frost or salts by reduction of initial surface absorption.
• Chloride free -safe in prestressed and reinforced concrete.

Application Instructions :

Where K Crete Ae is used in an existing mix design, the cement and aggregate proportions should be adjusted to take into account the increase in yield. The sand content can normally be reduced by about 20 kg/m for each additional 1% of air entrained.


Dosage :

The optimum dosage is best determined by site trials with the actual concrete mix which enables the effect of workability and air content to be measured. The rate of addition is generally within the range 100 ml to 300 ml KCRETE AE per 50 kg. cement according to the air content required. A dosage of 150 ml to 50 kg cement is normally sufficient to obtain 5%air entrainment.
