One unusual thing about coverage of cement in the media is the way that discussions often centre precisely on its absence – that is, on alternatives to cement. These alternatives boast unique chemistries and performance characteristics, but are all produced without Portland cement clinker. They are generally called ‘alternative cements,’ perhaps because ‘cement-free cement’ does not have […]

Novel concretes developer Greencraft has made a patent application for a new method of CO₂ mineralisation using a microporous material containing mineral oxides, like slag. Global Warming Focus News has reported that the method also works for natural hyaloclastite, bottom ash, fly ash, volcanic ash and lava. Greencraft said that its method marks an ‘improvement’

About the company “Eastgas SRL” “Eastgas SRL” is a leading supplier of blast furnace slag in Romania. We specialize in selling two types of slag: 1. Air-cooled blast furnace slag (ACS or ACBFS). 2. Granulated Blast Furnace Slag (GBFS). The company strives to provide sustainable and efficient solutions for the construction industry, contributing to environmental

A study at the DPG Institute of Technology and Management in Gurugram investigated the effects of blending different concentrations of silica fumes with ground granulated blast furnace slag-based (GGBFS) geopolymer concrete. Findings reported in Nature concluded that the addition of 10% silica fumes ‘significantly’ enhanced the durability and strength of the resulting concrete Chemical Composition

Market Dynamics and Growth Projections The global slag market, valued at $28.3 billion in 2024, is projected to reach $32.1 billion by the end of 2025, driven primarily by the construction sector’s increasing focus on sustainable materials. Steel slag, in particular, has experienced a remarkable 18% increase in utilization rates over the last quarter. Revolutionary

Nanomaterial Bitumen Breakthrough Disrupts Traditional Asphalt ManufacturingDecember 9, 2024Cutting-edge nanotechnology is revolutionizing bitumen production, with researchers from the Tokyo Advanced Materials Laboratory unveiling a microscopic approach to road construction materials that could redefine infrastructure resilience.The breakthrough centers on synthesized graphene-enhanced bitumen nanocomposites, which introduce unprecedented molecular-level modifications to traditional asphalt binders. By integrating carbon nanostructures

This year’s EuroSlag Conference in Bilbao, Spain, felt like more than just another industry gathering—it was a glimpse into the future of slag as a cornerstone of sustainable development. Industry leaders, innovators, and policymakers came together to exchange ideas and, more importantly, take decisive steps toward harnessing slag’s untapped potential. A Focus on Decarbonization and

Although less prominent than bitumen, slag—a by-product of metallurgy—plays a critical role in construction and sustainability: Reuse in Construction Slag is increasingly utilized in cement production and recycled aggregates, significantly reducing the carbon footprint of infrastructure projects. Innovations in Processing Advances are being made in utilizing slag as a base material for roads and dams,

The global bitumen industry is witnessing several significant developments: Increased Demand for Polymer-Modified Bitumen (PMB)Products like Nypol RE, launched by NYNAS AB, incorporate biogenic materials, offering extended durability and reduced environmental impact. These materials are vital for promoting sustainability in construction projects (Mordor Intelligence, Fact.MR).
