CERATECH, a company specializing in high-performance cements using proprietary innovative chemistry, has announced that 11 major petrochemical facilities are currently using its corrosion-resistant and highly durable KEMROK cement.
CERATECH’s existing customer is utilizing the KEMROK material for its fourth concrete project and has planned to use it in three more projects.
KEMROCK's chemical-resistant cement system being used for construction of a sulphur trench.
Widgeon Construction has commenced its third trench reconstruction project in South Texas. The company’s owner, Roger Simons explained that using standard portland-based cements for this type of project leads to discoloration and flaking of concrete. Hence, to attain a higher level of durability, certain petrochemical firms are using costly epoxy coatings and special portland cements. However, the KEMROK cement prevents the need for epoxy coating.
In general, petrochemical facilities are prone to concrete corrosion risk due to the existence of sulphur content in petroleum. When sulphur is combined with water, it forms sulphuric acid, which in turn reacts with minerals present in standard portland cement and results in deterioration. The KEMROK does not use portland cement and hence eliminates deterioration.
Laboratory experiments and field applications have proven that CERATECH’s cement has high resistance to sulphuric acid. In addition, the KEMROK resists specialty chemicals, salts and several acids. Another important benefit of this cement is environmental sustainability. The KEMROK is made of 5% renewable and 95% recycled materials and is produced using a carbon-free process. Therefore, it offers higher levels of sustainability compared to conventional portland cement.
The KEMROK is a cost-effective material. It is available either as a packed concrete repair mix or in bulk quantity.
