A Revolutionary Admixture for High-Performance Concrete

E5® Internal Cure is the first admixture proven to provide internal concrete curing. It is designed to control the evaporation of mix water to ensure increased hydration of cement, replacing the need for traditional wet curing and curing compounds. This results in concrete that is highly durable and easier to pump, place, and finish. 

Superior quality and workability

Makes concrete easier to pump, place, and finish. This gives control back to the finisher, even in inclement weather conditions. 

Concrete built to last

Increases the density of the concrete matrix, creating a highly durable surface that is resistant to abrasion and chemical attack, even in heavy traffic and freeze-thaw environments. 

Reducing Shrinkage

E5® reduces drying shrinkage and curling by up to 70%, delivering flatter, more reliable slabs that last longer and protect your bottom line.

Sustainable product reducing carbon

Reduces drying shrinkage and curling. Eliminates topical chemicals, which reduces the carbon footprint of a construction project. For every 100,000 SF pour, 880 pounds of CO2 are eliminated. 

For every application

Can be added to every yard of concrete for various applications, including exterior pavement, parking garages, structural walls, columns, footings, civil infrastructure, interior slab on grade, and slab on metal decks.

Technical Data & Application

E5® Internal Cure is highly effective on its own or when combined with other E5® admixtures. If using multiple admixtures, it is critical to add each one individually to the concrete mix to ensure the fullest efficacy. The product has been tested by a third-party lab and qualifies for use as a concrete curing compound in accordance with ASTM C156-20.

Technical Specifications

Dosage

For all concrete applications, it is recommended that concrete trial mixes be conducted to determine the correct dosage rate.

 4 fl. oz. per 100 lbs (0.52–2.61 L/100 kg) of cementitious material 

Mixing

For best results, E5® Internal Cure should be introduced to the concrete mixer at the ready-mix location. It is recommended that the combined materials be mixed for approximately 70 revolutions.

 Add directly at the batch plant; ~70 revolutions recommended before placement 

Environmental Impact

The product has a carbon footprint (Cradle to Gate) Global Warming Potential (GWP, 100 years) of 6.67 pounds of CO2 per gallon.

Carbon Footprint: 67 lbs CO₂ per gallon (EPD cradle-to-gate)

For Best Results

Compatibility: Works alone or with other E5 admixtures (add separately for best results)

Storage: 40°–130°F; 18-month shelf life; protect from freezing and sunlight

Packaging
E5® Internal Cure is available in pails (5 gallons), drums (55 gallons), totes (275 gallons), and tankers (bulk).
