US: Çimsa has started production at its new grey cement grinding facility in Houston through its subsidiary Cimsa Americas Cement Manufacturing and Sales Corporation, according to Yatirimlar news. The plant has an annual capacity of 600,000t/yr and commanded an investment of US$82m, reportedly making Çimsa the first and only Turkish cement producer with grey cement production operations in the US.

The company, which already operates a 300,000t/yr white cement grinding plant in the country, said the new facility strengthens its position in the US market by adding grey cement production capacity.

CEO Umut Zenar said “Our goal in doing so was to transform Çimsa into a global building materials company with both geographical production diversity and a differentiated product range. During this process, we strengthened our existing operations while continuing our path with international acquisitions and new investments. With the acquisition of the Bunol factory in Valencia, Spain, which we completed in 2021, we became the world's second largest producer in the white cement market. Then, with the Mannok investment we completed in 2024, we strengthened our presence, especially in Ireland and the UK, and accelerated our transformation with the new products we added to our portfolio. Today, we are happy to launch our new investment in the USA. We have been present in the US market for a long time through exports. This new investment, which we have implemented within our US-based company, is a turning point for us. We are no longer a brand that only exports to the USA, but also a player with on-site production power. In this way, we gain logistical advantages and offer much more to our customers. We will be able to provide fast and efficient service. We also aim to increase our sales volume and strengthen our market position with our local manufacturing capabilities in the US. It will also contribute to increasing the share of our foreign currency-based revenues.”

US: Silvi Cement, a division of Silvi Materials, has announced a significant expansion of its cementitious materials distribution network, with new facilities in North Carolina and Ohio.

The company has opened a temporary cement rail load-out facility at the deep-water port of Morehead City, North Carolina, now fully operational for pickup and delivery. Construction is also underway on a major cement import terminal at the same site, scheduled to open in 2027. The upcoming terminal will feature two 100,000t domes for Type I/II low-alkali cement and Grade 120 slag, with round-the-clock truck loading and direct rail loadout capabilities.

Silvi is simultaneously developing a large-scale, rail-served cement distribution terminal in Central Ohio, expected to open in spring 2026. Designed to handle over 250,000t/yr, the facility will distribute Type I/II low-alkali cement and Grade 120 slag to meet rising demand across the Midwest. Until the Morehead City domes are completed, both terminals will be supplied by rail from Silvi’s flagship cement terminal in Bristol, Pennsylvania, which houses three domes with a combined storage capacity of 165,000t.

US: CRH has finalised its US$2.1bn acquisition of supplementary cementitious materials (SCM) supplier Eco Material Technologies. CRH previously announced the agreement on 29 July 2025. It said that the acquisition is expected to ‘unlock significant future growth opportunities.’

US: Ash Grove Cement, part of CRH, has deployed Boston Dynamics’ autonomous robot ‘Spot’ at its cement plant in Washington in a year-long pilot to boost efficiency and safety. Operating more than 80 hours a week, the four-legged robot conducts routine inspections using a 4K camera and laser scanning, detecting anomalies and alerting teams before failures occur.

The company said that the robot can measure refractory bricks inside cement kilns, reducing risks by keeping employees out of hazardous environments. During the trial, Spot detected a failing bearing in rotating equipment, preventing unplanned downtime. Ash Grove said that the technology improves site safety, frees skilled teams for complex work and enables real-time monitoring in the hot and dusty conditions at the plant.

Plant manager Andy White said “Our aim for Spot is that, at the moment, we don’t have preventative or proactive maintenance routines on night shifts and the weekends. And, also, our labour force has to spend a lot of time recording data rather than analysing it… Spot can do this for us. When we come in the mornings, we already have reported generated, so we can proactively fix those issues thather than spending eight hours trying to find them.”

US: Martin Engineering has launched its two-wheeled Martin Gen 4 Railcar Opener. It is designed to aid bulk handlers to unload unprocessed and processed bulk materials from rail transport to facilities, including cement plants and terminals. The fourth generation product is intended to improve ease of use and reduce potential hazards for workers.

Features of the latest version of the railcar opener include simple manoeuvrability and lateral turning wheels for moving capstans, outrigger support and height adjustment. A ‘stepped’ drive tip is also intended to improve the gate opener’s contact with the capstan. This new design boosts efficiency, leading to less demurrage from stalling and a safer workplace.

Marty Yepsen, Business Development Manager for Railcar Unloading Products at Martin Engineering said “We’re excited about the 4th generation of this model because it’s been painstakingly designed over years using real-world feedback from customers.” He continued, “The nearly effortless single operator design transforms a hazardous and gruelling job into a comparatively routine and risk-free task,” Yepsen concluded. “Field tests have shown that the Gen 4 not only improves efficiency, which lowers demurrage, but it also increases safety and reduces labour costs. All this drives down operating costs and boosts ROI.”

Martin Engineering builds products for bulk materials handling. The company has its headquarters in Neponset, Illinois. It runs subsidiaries in Australia, Brazil, China, Colombia, France, Germany, India, Kazakhstan, Indonesia, Malaysia, Mexico, Peru, Spain, South Africa, Türkiye, the UK and the US.

China/US: A team led by Fengyin Du, then at Southeast University in Nanjing, developed a new cement formulation that reflects sunlight and emits heat more effectively than ordinary Portland cement, according to the New Scientist. The cement incorporates reflective ettringite crystals on its surface, which Du says “works like a mirror and a radiator, so it can reflect sunlight away and send heat out into the sky, so a building can stay cooler without any air conditioning or electricity.”

To make it, the researchers produce tiny pellets from limestone and gypsum, which are ground and mixed with water before being poured into a silicone mould covered in small holes. Ettringite crystals grow in slight depressions on the surface created by air bubbles, while an aluminium-rich gel allows infrared light to pass through, lowering heat retention.

Du said that tests at Purdue University, Indiana showed the cement’s surface was 5.4°C cooler than the air and 26°C cooler than conventional cement under the same conditions. The process is reportedly scalable and costs US$5/t less than ordinary Portland cement, as it can be produced at lower temperatures.
