Low-carbon construction
Sika is developing next‑generation solutions that reduce clinker content, integrate circular resources, and unlock new chemistries for sustainable cementitious systems. These collaborations strengthen our innovation ecosystem and reinforce Sika’s commitment to enabling low‑carbon construction worldwide.
Sika is deepening its exploration of calcium carbonate as more than a traditional filler. Research efforts are focused on understanding how this abundant mineral can play an active role in cement hydration and clinker reduction. This work aims to open new pathways that enhance performance while lowering environmental impact—supporting Sika’s broader ambition to reduce CO₂ intensity in mortar formulations.
We are advancing solution that incorporate secondary raw materials to support circularity in construction. One key area of development is the use of by‑product mineral components, such as slags, which offer new opportunities to reduce clinker content and introduce novel mineralogical levers for low‑carbon construction systems.
Sika is developing tailored cellulose ether technologies optimized for next‑generation blended and low‑clinker cements. By combining deep expertise in polymer chemistry with our own formulation and application know‑how, we are targeting improved robustness, adhesion, flexibility, and long‑term performance—even under challenging climatic conditions. This ensures that sustainable mortar systems continue to deliver the high quality expected in tile adhesives, renders, and EIFS applications.
Innovation efforts also include the evaluation of new binder concepts and supplementary materials that increase reactivity and efficiency. The exploration of alternative minerals, such as forms of anhydrite, illustrates how non‑traditional chemistries can support faster strength development and more resource‑efficient mortar solutions.
One Integrated Sustainability Journey
Across all focus areas, a clear and interconnected innovation landscape is emerging—one that spans mineral components, polymer technologies, and multiple CO₂‑reduction pathways. Collaborative development adds unique expertise from across the industry and accelerates Sika’s transition toward more sustainable, high‑performance cement and mortar technologies.
Through joint efforts with suppliers, market partners, and specialists, Sika continues to strengthen its position as a leader committed to driving meaningful change. By combining complementary strengths, we are helping shape a more sustainable built environment and supporting the industry’s evolution toward low‑carbon construction. This integrated approach not only reinforces our innovation capabilities - it underscores our long‑term commitment to shaping the future of sustainable construction.
