Improve the performance and environmental responsibility of your concrete with high-quality Limestone filler. Our UK-produced Limestone mineral is an effective concrete additive, helping reduce clinker content, lower carbon impact and maintain the strength and durability your projects demand.
With UK standards now permitting up to 20% Limestone filler in concrete, producers can achieve significant carbon savings, cost reductions and better concrete workability. LKAB Minerals supplies consistent, high-purity Limestone filler from multiple quarries to ensure logistical efficiency and to help meet your mix design and environmental goals.
Whether you’re working on large-scale infrastructure or ready-mix concrete production, LKAB Minerals understands how critical material performance is to delivering durable, high-quality results. Our technical experts can advise you on the right Limestone filler grade and inclusion rates for your mix, so you benefit from an efficient, proven concrete additive that meets today’s UK standards.
Limestone filler as a concrete additive offers clear advantages: it optimises packing density in the cementitious system, improves workability and finish, and helps you lower the clinker factor — the main source of embodied CO₂ in concrete.
With around 8.7 million tonnes of cement produced in the UK every year, the potential to replace up to 20% of this with Limestone filler means millions of tonnes in carbon savings.
