US: A team from Washington State University (WSU) and Pacific Northwest National Laboratory has successfully used waste crustacean shells in the production of concrete. ZME Science News has reported that the materials consist of calcium carbonate and 20 – 30% chitin, a nanoparticle biopolymer. When used as an additive in concrete production, the shells increase the set product’s compressive strength by 12% and its flexural strength by 40%. The team is now developing a methodology for the industrial-scale production of shell-based additives.
WSU researcher Professor Michael Wolcott said “Those are very significant numbers. If you can reduce the amount that you use and get the same mechanical function or structural function and double its lifetime, then you’re able to significantly reduce the carbon emissions of the built environment.”

GCC to expand Odessa cement plant
04 August 2022US: GCC plans to invest US$750m in an upgrade to its 0.9Mt/yr Odessa cement plant in Texas. The Milenio newspaper has reported that the upgrade will more than double the plant’s capacity to 1.9Mt/yr and lower its CO2 emissions per tonne of cement by 13%. GCC expects the new capacity to be operational by 2025.
The group said “GCC will carry out the project at the Odessa plant because the US market is developing faster and represents savings in freight compared to the plant located in Chihuahua, Mexico.”

Its consolidated sales, including those of its Brazilian and Mexican businesses, were US$2.41bn, up by 18% from US$2.05bn.
The group recorded cement sales volumes of 14.2Mt, down by 4.1% from 14.8Mt. Volumes fell by 27% in Eastern Europe and by 28% in Italy, but rose by 27% in Central Europe and by 8% in the US. Excluding Russia, the producer’s fuel costs per tonne of cement rose by 8.8% year-on-year to approximately Euro8.80, and its total energy costs rose by 20% year-on-year to Euro234m.
It implemented continued price rises across all markets except Mexico during the half, with the sharpest rises recorded in Italy and Ukraine.
US: Calucem, part of Cementos Molins, plans to establish a new calcium aluminate cement plant in New Orleans, Louisiana. The company will invest US$35m in the project and expects to commission the plant in mid-late 2023. It expects to create 70 new direct jobs and a total of 228 new jobs locally.
Calucem president and chief executive officer Yuri Bouwhuis said “Calucem is taking on a new investment that will support our growth and diversification in the US and ensure that we continue to offer high-value products to our global customers. Our choice of Louisiana for our first all-new manufacturing project in the US is due to the availability of strategic raw materials such as limestone and natural gas, access to waterways and skilled labour and the long history of using speciality cement products in the US.”
Holcim completes SES Foam acquisition
01 August 2022US: Holcim has successfully acquired leading US independent spray foam producer SES Foam. SES Foam has a track record of double-digit growth and expects to record sales revenues of US$200m in 2022, according to Holcim. The group says that the producer stands out for its value-added services to contractors, including onsite technical instruction, business consulting, branding and lead generation support.
Global head of solutions and products Jamie Gentoso said “I warmly welcome all SES employees into the Holcim family.

We look forward to entering our next era of growth together.”
France: Despite a 12% year-on-year increase in consolidated sales to Euro1.75bn from Euro1.56bn, Vicat recorded a net income drop of 17% to Euro77.8m from Euro93.5m in the first half of 2022. The group attributed the decline to increased global energy costs and to non-recurring industrial costs in France, India and the US. These costs included investments in exceptional maintenance at its Montalieu cement plant in France and a debottlenecking capacity expansion at its Kalburgi, India, cement plant. Geopolitical events also impacted the profitability of the producer’s business in Mali. Group cement sales rose by 17% year-on-year to Euro1.1bn.
Chair and chief executive officer Guy Sidos said “The basis for comparison in the first six months of 2022 was unfavourably high given the sales and profitability levels achieved in the same period of the previous year.”
US: Eagle Materials offset higher energy and maintenance costs by raising the prices of its products in the first quarter of its 2023 financial year. This contributed to an 18% year-on-year sales rise to US$561m. The group achieved earnings before interest, taxation, depreciation and amortisation (EBITDA) of US$184m during the quarter, up by 13% year-on-year.
President and chief executive officer Michael Haack said "Our results this quarter exceeded our expectations, as our portfolio of businesses performed well, and we executed on the opportunities available to us. Construction activity remained healthy across our markets, and we realised broad pricing gains across our portfolio again this quarter."
The producer’s cement sales rose by 5% year-on-year to US$285m. Haack said "In our heavy materials business, we implemented a second round of cement price increases in early July 2022 given the strong demand environment and our sold-out position. Looking ahead, we expect demand for cement to remain strong, with infrastructure investment increasing as federal funding from the Infrastructure Investment and Jobs Act begins in earnest this fiscal year.”
Mexico: GCC increased its sales revenue by 11% year-on-year to US$320m in the second quarter of 2022. Its US cement sales volumes rose by 6%, with a 10% rise in prices, while its Mexico cement volumes fell by 2.3%, with a 12% rise in prices. The group’s cost of sales was US$220m, 69% of total sales, compared to 67% in the second quarter of 2021.
Mexico: Cemex’s consolidated sales grew by 9% year-on-year to US$7.85bn in the first half 2022 from US$7.2bn in the same period in 2021. It sold 32.1Mt of cement, down by 4% from 33.6Mt. Its cement sales volumes rose by 4% in its US and by 1% in Europe, the Middle East, Africa and Asia, but fell by 10% in Mexico and by 3% in South and Central America and the Caribbean. The group says that record levels of alternative fuel usage and a lowered clinker factor helped it to reduce its total CO2 emissions by 3% year-on-year in the reporting period.
Chief executive officer Fernando González said “I am pleased that our pricing strategy is yielding results and has fully offset inflationary costs in the second quarter of 2022. With improved supply chain dynamics and continued success of our pricing and cost containment strategies, we remain confident we can recover 2021 margins.
