DRYCRETE AS A CURE

How can Drycrete products be used as a curing medium, while conventional silicates cannot?

The American Concrete Institute (ACI), states that conventional silicate solutions simply cannot act as a curing medium because they do not:
"... maintain moisture and temperature conditions in a freshly placed cementitious mixture to allow hydraulic cement hydration and (if applicable) pozzolanic reactions to occur so that the potential properties of the mixture may develop.“

They further state that conventional silicates could improve concrete durability if applied after proper curing.

On this point, both ACI and the manufacturers of conventional silicate solutions agree - silicate solutions "should not be applied on fresh concrete."

Since conventional silicate solutions are more viscous than the water filling the surface pore structure of fresh concrete, silicate solutions cannot "penetrate properly and will not chemically react as intended.

Concrete samples treated with DRYCRETE™ products have been tested and compared to water cured samples, and demonstrate equal or superior performance on the following tests:

• Compressive Strength (7% Increase)
• Flexural Strength (15% Increase)
• Abrasion Loss (50% Reduction)
• Surface Dusting (31% Reduction)
• Water Permeability - Tested over 100-foot Head Pressure (89% reduction)
• Water Permeability - USACOE C48 @ 100-foot Head Pressure (0 Leakage)
• Water Permeability - DIN 1048 @ 72.9-psi Pressure (94% Reduction)
• Freeze-Thaw Resistance (85% Improvement)
 
Over the past two decades, DRYCRETE Products have consistently demonstrated, through testing and field observations, that they achieve the intent of ACI's definition for curing even though no surface membrane is formed.

PREVENT BLUSHING

Whitening of concrete sealers – also known as ”Blushing”
+

PREVENT SPALLING

When the water in concrete is able to freeze, it then expands & causes damage to concrete surfaces.
+

PREVENT MOISTURE ISSUES

Leaves no surface residual to impede or hinder bonding of any coatings or adhesives.
