Interesting article: Groundbreaking Cement-Free Concrete a Game Changer in Construction Cement-free concrete is a revolutionary material that aims to reduce the environmental impact of traditional concrete by eliminating cement from the mix. Cement production is a significant contributor to greenhouse gas emissions, so finding alternatives is crucial for sustainable construction. Instead of cement, cement-free concrete uses other binding agents, often derived from industrial byproducts. Some common approaches include the Alkali-Activated Cementitious Materials (AACM) that activate pozzolanic substances like ground granulated blast-furnace slag (GGBS) and pulverized fly ash (PFA) to create a binding agent.

What happens to aggregates in UK construction? The environmental impact of concrete extends beyond the large carbon footprint of clinker production. Aggregates do not have a significant embodied carbon footprint, but the sheer volumes involved mean it’s important to explore this from a material and land use perspective. With the help of KLH Sustainability, HTS+ explored the impacts of raw material extraction in this new study on aggregates, and identified that there is limited data at present on where recycled and secondary aggregates (RSAs) get used. This summary sets out the insights of the research and seeks to open a conversation on what happens to aggregates in UK construction.

Cement is the major contributor to the embodied carbon of concrete. Reducing the cement content can significantly decrease the carbon footprint. Besides, incorporating industrial by-products like GGBS as a partial replacement for cement, leads to a considerable reduction in embodied carbon, making concrete more sustainable.

Look to a ‘first attempt’ website www.techno-carbon.uk It is no longer about how we use cement or concrete or steel more efficiently. It IS absolutely about - ‘How do we effect a smooth transition away from these materials?’ One way is a transitional material called ‘carbonfibre concrete’. It literally changes concrete into a shock absorbable material.

Exploring the Potential of Polymerized Sulfur Concrete in Modern Construction - In the dynamic landscape of construction and energy materials, polymerized sulfur concrete (PSC) is proving to be a remarkable discovery. Beyond its groundbreaking role in hydrogen storage, PSC is emerging as a crucial material for building flood-resistant structures, influencing the insurance industry. Known for its extraordinary properties, PSC is revolutionizing energy storage, providing robust solutions in construction, addressing the pressing challenges of climate change, and offering new avenues for sustainable development, including integrating green concrete technologies. Understanding Polymerized Sulfur Concrete Composition and Creation Polymerized sulfur concrete (PSC) is an innovative construction material that combines sulfur with aggregates such as dune sands and other additives. Unlike traditional concrete, which relies on Portland cement as a binding agent, PSC utilizes polymerized sulfur to achieve its unique properties. The composition of PSC includes polymerized sulfur, which constitutes about 32.5% of the mixture, 32.5% dune sands, 17.5% limestone filler, and 17.5% ground granulated blast furnace slag (GGBFS).

A new set of international definitions for low-carbon cement and concrete, which will help to expedite the decarbonisation of the construction sector, have been unveiled by the GCCA – Global Cement and Concrete Association (GCCA). "We now call on policymakers, governments and the private sector to procure green cement and concrete and provide the key signals to our sector to accelerate decarbonisation," commented Thomas Guillot, chief executive of the GCCA. #concrete #cement #decarbonisation #construction Read more: https://lnkd.in/eWpYEmtV

Today is Earth Day, a time to celebrate and showcase the steps the cement industry is making toward a more sustainable future via its Roadmap to Carbon Neutrality. Here are some inspiring ways our member companies are making a positive impact: ✅ Reducing their clinker factor by manufacturing lower-carbon blended cements such as Portland Limestone Cement ✅ Reusing steel slag in manufacturing as a raw material ✅ Relying on solar energy to power their plants ✅ Using biomass and other materials as fuel that would otherwise go to landfills ✅ Adopting electric vehicles in their fleets ✅ And much more, with more to come. Our commitment to a better planet is not just a fleeting moment—it’s an ongoing commitment. Together, we can make a difference!   #PCAroadmap #CementIndustry #EarthDay2024
