![]() Acid attack was conducted at 28 days and autogenous shrinkage of the SF concrete was investigated using length comparator at 28 day in SC and USC. The hardened properties of the SF concrete were investigated through the estimation of compressive strength (CS) and elastic modulus (EM) at 7, 14, 28, and 90 days, respectively. The workability of the SF concrete was examined at various levels of replacement by the slump cone test. ![]() The behavior of SF on the autogenous shrinkage of the concrete was studied for both the grades of concrete in the sealed (SC) and unsealed conditions (USC). Investigation on the performance of the SF was performed for M25 and M40 grades concrete with 0, 5, 10, and 15 % replacement levels at 7, 14, 28, and 90 days. The addition of silica fume to concrete was first tested in Norway in the 1950s.This paper involves the study on the hardened and durability properties of the concrete at two different grades containing silica fume (SF) with various replacement percentages. Collected in baghouse filters, it is a very fine pozzolanic material. Silica fume is a by-product of the silicon metal/ferrosilicon alloy industry. Once a nuisance waste product, silica fume is now a valuable addition to cement, creating concrete that is high strength, such as that used to build 311 South Wacker Drive, Chicago, once the world’s tallest reinforced-concrete building. Sustainable building materials: Facts & fairness.Policy Needs For Sustainable Construction.Public policy will play a central role in the ability of the industry and the wider value chain to decarbonise cement and concrete over their lifecycle. Concrete in Life 2022 – WINNERS ANNOUNCED.GCCA aims to provide all the required resources to its members to drive the sustainability agenda through the development of guidance and good practices sharing. GCCA’s Sustainability Charter shapes the GCCA’s ESG agenda, which covers all aspects of non-financial factors that help the cement and concrete sector to identify its key material risks and discover potential growth opportunities. Innovandi, the GCCA's innovation arm runs two key programmes to accelerate and unlock new technology that will be key in our sustainability journey.ĮSG is all about integrating the key principle of sustainability (people, planet, and profit) into day-to-day business. Innovation is a key part of the cement and concrete industry's journey to net zero and is a key part of our 2050 Roadmap. Support from our members, affiliates and stakeholders.Carbon capture, utilisation and storage.Biodiversity action for net positive impact.Providing the infrastructure for circular and net zero manufacturing.Creating market demand for carbon neutral construction and decarbonised value chains.Making low carbon cement manufacturing investable.Societal demand for cement and concrete.Full deployment of technologies to get to zero.2020 – 2030 – The decade to make it happen.What the roadmap means for GCCA members.GCCA 2050 Net Zero Roadmap Accelerator Program.Our 2050 Net Zero Roadmap sets out in detail how collectively, in collaboration with built environment stakeholders and policymakers, we will fully decarbonise the cement and concrete industry and provide net zero concrete for the world. Our Contribution to Achieving the UN SDGs.Sustainable Building Materials: Facts & Fairness.That’s because of its inherent benefits of strength, durability, resilience, safety and affordability to create vital infrastructure – roads and railways, homes, offices and the cites we live in. Representing 80% of the world's concrete industry outside of China, our mission is to position concrete to meet the world’s needs for a material that can build and support growing, modern, sustainable and resilient communities.Īs the most widely used material on earth after water, concrete is fundamental in shaping our world.
