EnviroAdd^®
Next Generation Activators for low carbon cement

Case studies

Concrete application

Status

• Concrete cured at 10°C with a constant water-to-cement
  ratio of 0.38.
• Same admixture and equal 100 mm slump at 45 minutes
  between both samples.

Results
EnviroAdd^® activators boosted early strength in concrete,

• outperforming traditional activators. Concrete strengths
  at 24 hours: +25% at 1 day when cured at 10°C.

LC³ activation

Status

Industrial trial with LC3-50 Cement (30% calcined clay, 15% limestone).

Results

Robust increases in compressive strengths :

• +38% at 1 day or + 5 MPa with EnviroAdd^® EL “C”
• +18% at 28 days or + 8 MPa with EnviroAdd^® EL “B”
• Customized EnviroAdd^® EL “A” met cement plant’s target performance at all ages

LC3 + “A” for example is a combination of LC3 and Customized solutions of EnviroAdd^®.

Customized EnviroAdd^® activators enable meeting the specific requirements of low-clinker cements.

Alternative Fuels

Status

• Switching from 100% fossil fuels, 50% pet coke and 50% fuel oil
  to 85% pet coke and 15% refuse-derived fuel
• Contributing to unfavorable kiln conditions

Results

• EnviroAdd^® activators offset the negative impact in strength due to
  the switch from fossil fuels to alternative fuels

Water Reduction

Status

• Cement Type 1P with 35% Calcined Clay
• EnviroAdd^® HWR tested at equal concrete admixture dosage

Results

• EnviroAdd^® HWR unlocks +22% strength gains while preserving
  workability for a long period, retaining 200 mm slump at 60 minutes.
