Concrete Admixtures

Weber Admixtures enhance concrete, resulting in higher strength, better fluidity and improved durability. Concrete admixtures consist of plasticisers, super plasticisers, hyper plasticisers & ancillaries that can withstand extreme environmental conditions and can be used for complex mix designs and for high rises.



Weber ADH2R is a water-reducing and retarding admixture for concrete. It enables easier placing, compaction and finishing of concrete and may be used to reduce the water content whilst retaining the same workability resulting in higher strengths. weber ADH2R may also be used to reduce the overall cement content for specified strength and durability. It can also improve the cohesion of concrete mixes based on materials having a higher water demand. weber ADH2R is preferred admixture for higher performance concrete (HPC) mixes containing micro silica or met kaolin.

Features
Allows retention of the origoinal slump over time in addition to the normal properties
Increases the ultimate strength of concrete
Reduces segregation and bleeding
Reduces thermal peaks
High workability for longer periods
Lower pumping pressure
Resistance to segregation at high workability
Reduced water content for a given workability
Higher ultimate strengths
Reduced Permeability
Improved durability
Reduced shrinkage and creep
Increased ease in finishing concrete

Recommendation
Weber ADH2R is ideal to use in normal to high temperature conditions where slump retention over time is important for transportation.
