Portland Composite Cement (PCC) is the result of years of research, and is a superior blended cement produced exclusively at the Puttalam integrated cement manufacturing facility earlier, to address the high carbon footprint of OPC cements, while also producing compressive strength equal to or beyond that of OPC at all ages.
“INSEE Cement introduced Portland Composite Cement for the first time to the local market last year as part of a two-pronged approach; to create value for our customers by augmenting the sustainability performance in their constructions, and also to steer Sri Lanka’s construction industry towards ambitious, globally benchmarked sustainable goals,” Dr. Moussa Baalbaki, Head of Products and Solutions Portfolio at INSEE Cement stated.
“Globally, the use of composite cements from residential and commercial to large-scale infrastructure projects have demonstrated long-term performance enhancements, and have contributed to reduce the carbon footprint in construction.
We are truly encouraged by the growing demand across the local market for Portland Composite Cement, and trust our production expansion to Galle is testimony to our commitment towards sustainable production practices.
Engineered with INSEE’s trademarked SmartActTM Technology, Portland Composite Cements unique composition of multiple minerals addition undergoes a triple reaction consisting of hydration, pozzolanic and nucleation that increases strength build-up at each level of maturity.
The triple reaction also ensures optimum particle distribution and high packing density, resulting in lower permeability and durability of concrete suitable for all severe exposure conditions across Sri Lanka, especially coastal regions. Impermeable concrete with less voids and percolated capillary pores effectively addresses the key challenges of rainwater penetration and ingress in concrete structures – a significant concern for homeowners in Sri Lanka today who are also steadily progressing towards the use and endorsement of PCC.
With the use of multiple silico-aluminates minerals such as slag and fly ash, Portland Composite Cement contributes to reduce carbon emissions both in production and construction practices, also making it a more environmentally friendly product than OPC.
INSEE strengthened its commitment to reduce carbon emissions in cement production under the INSEE Sustainability Ambition 2030, a group-wide sustainability plan with key targets and actions to support the globally accepted 2oC scenario, alongside the company’s increased use of by-products such as slag and fly ash replacing clinker in cement production.
Other well received advantages of Portland Composite Cement include its lower heat of hydration that makes the product favorable for mass concreting in hot weather conditions, and its high chemical resistance that makes PCC suitable for long-term infrastructure development projects such as dams, bridges, roads and other concrete elements.
