Incheon National University team develops cement-based conductive composites for net-zero energy buildings
24 November 2021South Korea: Researchers at Incheon National University have discovered an optimal conductive carbon fibre volume for cement-based conductive composites for use in net-zero energy buildings. The team reported that a 1% conductive carbon fibre content facilitates maximum energy generation from the movements of occupants and the weather against floors and walls. It also enables the storage of electricity at safe voltages. The product is based on triboelectric nanogenerator (TENG) technology.
The team published its results in the journal Nano Energy in November 2021.
Europe: US-based CASE Construction Equipment has won a contract to supply Cemex with a new fleet of backhoe and wheel loaders for its building solutions operations in the Czech Republic, France, Germany, Poland, Spain and the UK.
Europe regional mobile equipment fleet and category manager Craig Hooper said “As one of the world’s largest building solutions providers, Cemex is committed to leading on the path to a low carbon economy and is closely evaluating all areas of its business to make efficiency improvements. The vehicles we use as part of our work are a key part of this and we are pleased to have agreed this contract with CASE for these vehicles, which will provide a significant sustainability benefit to Cemex’s European operations. They incorporate advanced technology alongside lower fuel consumption due to an improved power to weight ratio. We look forward to working with CASE to explore other opportunities to enhance the eco-credentials of our fleet.”
Buzzi Unicem increases nine-month sales and cement volumes in 2021
08 November 2021Italy: Buzzi Unicem’s consolidated sales rose by 5.6% year-on-year to US$2.54bn in the first nine months of 2021 from US$2.41bn in the first nine months of 2020. It recorded consolidated cement sales of 23.4Mt, up by 7.5% from 21.7Mt in the corresponding period of 2020. Sales growth in Eastern Europe - especially the Czech Republic and Poland - and the US offset a partial slowdown in Italy, particularly in the third quarter of the year.
The group expects global construction activity to generally remain level into the fourth quarter of 2021. It forecast “favourable” volume and price effects in its full-year results for 2021. It nonetheless noted “growing concern” at rising energy, fuels, logistics, raw materials and services costs in various regions. It forecast group recurring earnings before interest, taxation, depreciation and amortisation (EBITDA) not in excess of 2020 levels.
Qizilqum Cement’s sales fall in first nine months of 2021
25 October 2021Uzbekistan: Qizilqum Cement’s nine-month sales fell by 11% year-on-year in 2021. A 4.4% decline in cost of goods sold failed to create earnings before interest (EBIT) growth during the period. The company recorded a 36% fall in EBIT.
Bluestone Investment Bank recorded 4.5% year-on-year growth in Uzbekistan’s volume of construction during the first nine months of 2021. In the first eight months of the year, its cement companies produced 8Mt of cement, up by 18% year-on-year. Cement imports rose slightly to 0.56Mt.
LafargeHolcim US collaborates with ECOncrete Tech on offshore wind turbine foundation scour protection unit development
15 October 2021US: LafargeHolcim US and ECOncrete Tech have launched a research and development collaboration to design and manufacture a fully structural concrete scour protection unit for offshore wind turbines. The unit’s specifications include seabed stabilisation and promotion of the growth of marine organisms. The collaboration includes a large-scale pilot project to evaluate the ecological performance of units in an offshore environment. The US/Canada Binational Industrial Research and Development (BIRD) Energy programme are funding the project, which will conclude in May 2024.
LafargeHolcim US commercial excellence vice president Josep Maset said “There are many paths to achieving our net zero commitment, and most require innovative partnerships and out-of-the-box thinking. The work we’re doing with ECOncrete Tech is a notable example of searching for solutions that enable increased use of renewable energy in an environmentally responsible way.”
Indian cement production forecast to reach 332Mt in 2022
14 October 2021India: Rating agency ICRA has forecast that Indian cement production will rise by 12% year-on-year to 332Mt in 2022. It said that pent-up pre-Covid-19 lockdown demand, rural housing demand and a pickup in infrastructure activity would drive the rise. ICRA predicted that demand would rise by a further 8% year-on-year to 358Mt.
In the first quarter of the 2022 financial year, domestic rose by 44% year-on-year and by 2% compared to the first quarter of the 2020 financial year to 142Mt. ICRA estimated that the top 12 Indian cement producers will record their highest ever average operating profit per tonne of cementitious material in the 2022 financial year. It said that this is likely to occur due to an increase in net sales realisation and cost optimisation measures.

US: Martin Marietta Materials has completed its US$2.3bn takeover of Lehigh Hanson’s West Region business. The acquisition enlarges the company’s cement assets by two new plants and related distribution terminals, as well as targeted downstream operations, in California and Arizona.
Chair, president and CEO Ward Nye said "We are pleased to complete the Lehigh West Region acquisition and welcome a talented group of new employees to the Martin Marietta team. These assets serve as a new growth platform for our continued geographic expansion and are uniquely positioned to benefit from favourable market dynamics and accelerating public and private construction activity in California and Arizona.” He added “We are confident in our ability to quickly realise the benefits of this transaction and deliver significant value creation for our shareholders, customers and employees following the same proven approach we took with our acquisitions of TXI and Bluegrass."
Croatia: Holcim Croatia plans to invest Euro1.28m to upgrade the dosing equipment of its Koromačno cement plant’s kiln line. The planned upgrade will enable the line to increase the proportion of alternative materials used in its cement production, thus equipping the plant for low-carbon cement production. Innovation Norway has granted the producer Euro441,000 towards the cost of the project.
Managing director Nikola Kovačević said “Mineral admixtures in cement have a threefold benefit: on the one hand, different characteristics are created in the cement to meet the requirements of different types of construction; on the other hand, the exploitation of natural resources decreases. Thirdly, the carbon footprint of the cement is thus reduced through the lowering of the clinker factor.”
UK: Global building materials supplier Cemex UK has launched its Buildings Made Better range of renovation and refurbishment products and services. The company says that the range offers customers easy access to low carbon, energy efficient or water-conserving building solutions. It includes a wide selection of existing and new products including its Vertua low carbon concrete. The producer said that the solutions support the construction phase and the whole lifecycle of the building.
Cemex Materials West Europe quality and product technology director Steve Crompton said “The renovation of existing buildings can lead to significant energy savings for all, as buildings account for over 40% of energy consumed. More than 220m buildings in Europe, representing approximately 85% of the building stock built before 2021, will mostly still be standing in 2050, yet currently only 1% of buildings undergo energy-efficient renovation each year. The energy performance of buildings is a major area for improvement in public policies, for new build and the renovation of the existing stock. From residential housing, to public buildings and urban schemes, across the board, we’re demonstrating to our customers that by improving the built environment, we can significantly improve our natural environment too.”
He added “Concrete has a critical role to play in the transition to a low-carbon economy. We have the aspiration to deliver net zero CO2 concrete globally by 2050, which will contribute to the development of climate-smart urban projects, sustainable buildings and climate resilient infrastructures. By bringing together a comprehensive range of sustainable products that support the important area of retrofit, we are offering our customers easy access to the right products for the job whilst keeping the environment front of mind.”
