Efflorescence Control Agent for Concrete
ConTec EC-45 is an integral water repellant admixture used in low slump concrete units such as architectural block, paving stones, SRW units, or masonry mortar. Using this unique formulation results in a chemical reaction with concrete to prevent water penetration and control efflorescence. ConTec EC-45 enhances the color and appeal of all types of concrete products. Use in both mortar and masonry units EC-45 reduces water infiltration through masonry walls.
Features & Benefits
- Increases hydrophobic properties and lowers absorption rates
- Impedes the formation of primary and secondary efflorescence
- Helps maintain color integrity throughout
- Aids color development and can shorten production cycles
- Improves compressive strength and density
Applications
ConTec EC-45 can be used in all types of manufactured concrete in which the reduction of efflorescence and water permeability is desirable.

TECHNICAL INFORMATION
ConTec EC-45 is available in totes and drums. An ICT representative will work with you to determine the proper dispensing system for your operation.
ConTec EC-45 should be stored at temperatures above 40°F (4.5°C). Never allow to freeze.
We recommend the following range of dosage: 8 to 16 US fl. oz. per 100 lb of cement for concrete paving stones and concrete roof tile. For SRW units and other architectural block higher dosage rates may be recommended. Order of addition procedures can vary per facility. Never mix EC-45 with other admixtures before application. Consult your ICT representative to help you determine the proper dosage rate and order of addition for your particular process.
