Blended Hydraulic Cement

Blended Hydraulic Cement

LANWA Blended Hydraulic Cement (BHC) is made by intergrinding the minerals chosen after extensive quality testing. The mineral mix proportions are controlled to deliver the expected product performances while meeting stringent environmental and construction requirements.

Designed for aggressive environments subjected to severe chloride attacks and carbonation, LANWA BHC is composed to use on large constructions, including bridges, dams, ports, underground constructions, etc. The optimized attributes of LANWA BHC would increase the durability of concrete and enable prolonged service life. LANWA BHC is chemically resistant and emphasizes the reinforcing steel in concrete's ability to resist corrosion, which prevents concrete structures from cracking due to corrosion of the steel reinforcement. Further, increased carbonation resistance and extended service periods would be provided by structures built with concrete of LANWA BHC. As an outcome, LANWA BHC can effectively use to develop tailored concrete solutions for harsh environments such as coastal areas.

LANWA BHC's reduced water demand would optimize the cost of concrete while delivering higher strengths with lower cement contents. Placing and compaction of the concrete will be easier with LANWA BHC while maintaining the workability of the concrete for extended periods. Produced for specified constructions in aggressive environments, LANWA BHC complies with the SLS 1247:2015 quality requirements set by Sri Lanka Standard Institute.

product features

Exceptional Concrete Performance.

LANWA BHC is the best choice for producing concrete with exceptionally fresh and hardened properties. The subdued water consistency and extended setting time of LANWA BHC assure superior workability of concrete mixes. Furthermore, it guarantees the enhancement of the performance of concrete in the face of raw material scarcity. The fineness and proportion of slag in LANWA BHC are chosen to provide the highest concrete strengths, making it an ideal solution for developing high-performance concrete mixes.

Hostile Environment Conditions

LANWA BHC would be an ideal preference for increased concrete protection in adverse environmental conditions. By preventing the reaction and permeability of chloride ions, the slag reaction of LANWA BHC ensures the highest resistance to chloride attacks. Therefore, concrete structures made with LANWA BHC will prolong last in hostile environments without regular maintenance.

Mass Concrete Applications

Encouraging mass concreting applications, LANWA BHC expands the faster and more efficient construction opportunities for reinforced concrete structures. The risk of reducing the concrete durability due to delayed ettringite formation (DEF) and thermal cracking can easily be controlled by using LANWA BHC. As a result, LANWA BHC might use to enhance the volume of concrete used in a single pouring, which decreases construction costs.

Best Concrete Economy

The lowered retarding chemical agent requirement of LANWA BHC allows you to produce time-extended concrete mixes at a lower cost. Further, LANWA BHC can be mixed with additional quantities of GBFS/FA to develop the concrete properties and increase the likelihood of large concrete pouring.
