OPTEC® EC-140 admixture offers a new level of efflorescence control to the concrete hardscape industry. It is formulated as a ready-to-use admixture to enhance the quality and appearance of concrete pavers and segmental retaining wall units.
OPTEC® EC-140 admixture has been especially designed for the efficient production of concrete pavers and segmental retaining wall units. However, it can also be used in other manufactured concrete products such as architectural concrete masonry units and concrete brick.
OPTEC® EC-140 is compatible with most concrete admixtures, but when multiple admixtures are used they must be added separately to the concrete mixture.
OPTEC® EC-140 admixture is typically used at a rate of 4-9 oz/cwt (260-590 mL/100 kg) of cementitious materials, including pozzolans. The addition rate is dependent upon the specific set of materials and the desired end properties.
OPTEC® EC-140 admixture will produce a swipe on the molded surface of the unit.
For maximum product efficiency add OPTEC® EC-140 admixture to pre-wetted aggregate or after the cement has been wetted. As with all admixtures, do not add OPTEC® EC-140 admixture to dry cement. Allow an additional 60-120 seconds mix time, after all the admixture has been added.
All precautions defined on the SDS (Safety Data Sheet) for OPTEC® EC-140 admixture must be followed.
OPTEC® EC-140 admixture is available in drums and returnable totes.
OPTEC® EC-140 admixture will begin to freeze at approximately 32 oF (0 oC), but will return to full strength after thawing and thorough agitation.
