Light weight water proof concrete

Traditional solutions using bituminous coatings

All this destructive reactions require water. Hence, keeping the concrete dry is an important feature for concrete protection and maintenance. Bituminous coatings are reported to have limited durability and after a while the corrosion process will start due to its weak interfacial film failure that occurs overtime. The limited mechanic-ability and penetrability to protect the surface deeper from the concrete surface does not provide the protection needed due to attack of anions toward the passive steel in the concrete matrix. At the same time rendering bituminous coatings prone to adhesion failure, wherein durability is weakened by the elements over varying weather conditions.

CM9007 is an integral admixture for waterproofing of concrete, GFRC, or other types of polymeric cementitious mixes.  For use in reducing water ingress and water absorption able to meet 1.0% maximum water absorption level according to recommended dosage.  Tested according to British Standard (BS 1881: Part 122: 1983).  Increases compressive and flexural strength properties, and densifiies the film upon cure.  The final result provides long term protection from corrosion on structural reinforced concrete, and efflorescence protection from various salt build-ups.

Basic Benefits of Concrete made with Elemix Additive 

Elemix concrete additive has several properties that are advantageous to use in concrete, including:

Ø Reduces Concrete Weight

o Delivers targeted densities while achieving structural compressive strength

o Reduced concrete weight can contribute to overall reduction of building costs or for manufactured products contributes to reduced transportation costs

o Enables concrete to be used in new design opportunities

Ø Product / Performance Consistency

o Elemix additive is manufactured under tight tolerances resulting in consistent performance properties, therefore reducing the overall variability in concrete mixtures

Ø Durability

o Good durability increases the life of the concrete structure reducing long-term costs

o Elemix concrete additive has been shown to impart freeze-thaw resistance with durability factors ≥ 80% without the use of air-entraining admixtures

o Studies of concrete containing Elemix additive have generated concrete with low to very low chloride ion penetrability

Ø Ease and Efficiency of Placement

o Concrete made with Elemix additive pumps, places and finishes easily by traditional methods. The non-abrasive nature of the product contributes to less wear on equipment.

Ø Cracking Performance

o Studies at Purdue University reveal that the use of Elemix additive in concrete gave crack reduction ratios, associated with plastic shrinkage cracking, of up to 85% versus a control. Improved cracking performance was also evident in restrained shrinkage cracking tests where the addition of Elemix additive increased the time to cracking or in some cases enabled samples to not crack.

Ø Thermal Performance

o Concrete made with Elemix additive will improve thermal resistance based on the reduced unit weight.

Addition to Concrete

Elemix concrete additive is supplied to concrete batches by weight or volume. Elemix additive is easily added manually to batching equipment or directly to mixers.
