D5 Green is a highly innovative, multifunctional additive for concretes, mortars, dry building mixtures, grouts and cements. It significantly increases the strength of concrete, allowing a substantial reduction in cement content and carbon  footprint.

Increase concrete strength

​

Boost early strength

Reduce cement content

Reduce carbon footprint

​

Improve durability

Accelerate setting time.

Reduce cement content and carbon footprint

Cement production is estimated to account for 8% of global carbon emissions.

​

Using D5 Green at 2-3% can reduce cement content and lower the carbon footprint of concrete by 20% (or up to 41% when used with supplementary cementitious materials), without impairing its performance.

Increase strength

D5 Green increases the strength of concrete by 25%-35% when added at 2-3% of cement mass.

​

D5 Green has been used in constructions with stringent strength and durability requirements.

Accelerate setting time

D5 Green accelerates the strength setting of concrete. Independent testing shows an increase in day 1 strength by 70% - 140% and significantly earlier achievement of target 28- day strength.

For this reason, D5 Green has been used in projects where developers needed to considerably decrease the 

period of construction or remove formworks early.

Boost early strength

D5 Green boosts the early strength of concrete, making it attractive for precast concrete. Independent testing shows an increase in overnight strength by 70% - 140%. This means that even when used with fly ash, high overnight strength is achievable for concrete with D5 Green.

​

For this reason D5 Green has been successfully used in precast panels by Concretec in the Auckland City Rail Link project, where fly ash was specified. 

As a cementitious powder or mixture, D5 may cause skin and eye irritation if not handled with care, may

be harmful if inhaled or swallowed.

As a precautionary measure, please use outdoors or in well-ventilated area, and wear personal protective equipment:

goggles, gloves and a respirator, ensure access to flowing water. 

Dosage

Recommended dosage is 2%-3% of cement content (efficiency increases with dosage).

Mixing

D5 GREEN should be added into a concrete mixer in dry form together with sand or cement and should  be thoroughly mixed for at least 30-60 seconds to ensure even distribution through the mixture. Note, that water content should be reduced by  15-20%, compared to concrete of the same target slump but with no admixtures. Trial mixes are recommended to establish the exact water content. 

Concrete Placement

To achieve the best results with D5 GREEN, the normal good practices for concrete placement and curing should be observed. 

Storage And Shelf Life
