September 2026

The September issue of World Cement begins with insights from North America courtesy of Amrize and Cemex US as the two explore developments in the low-carbon building materials sector. The rest of the issue then moves on to cover: Grinding & Milling, Additves & Admixtures, Electrification, Condition Monitoring & Predictive Maintenance, and low carbon cements.

But that’s not all! September also comes bundled with our Bulk Materials Handling Review (BMHR) special issue that takes a deep dive into the often overlooked, but essential technologies that keep everything from raw materials to finished products moving around cement plants and related facilities.

This month's front cover is brought to you by Thyssenkrupp.

REGIONAL REPORT: NORTH AMERICA

Modernising For Tomorrow
Amrize reveals how it is modernising operations across Canada to improve efficiency, expand capacity, and deliver lower-carbon building materials for tomorrow’s infrastructure.

From Carbon Targets To Concrete Reality
Justin Dickey, Cemex US, explores how early-stage collaboration and the use of blended cements and supplementary cementitious materials are enabling lower-carbon concrete for hyperscale data centre construction.

COVER STORY: GRINDING & MILLING

Powering Performance With Wear Protection
Stephan Vilbusch, thyssenkrupp Polysius GmbH, explores how long-life compound cast rollers support stable HPGR grinding and underpin reliable, high-performance plant operation.

ADDITIVES & ADMIXTURES

Clinker Cutback Chemistry
Alejandro Velez, Sika Services AG, RymKenza Belhaj, Sika Maroc SA, and Mohsen Ben Haha, Sika Technology AG, explore how integrated chemical additives and process optimisation strategies enable clinker reduction while maintaining cement performance and efficiency.

Siloxane Strength Solutions
Dr. Wei Cai, Jim Greene, and Liang Jia, Wacker Chemical Corporation, examine how siloxane-based admixtures enhance moisture resistance and durability in lower-carbon cementitious systems.

ELECTRIFICATION

Electric Economics
Dr. Nate Weger, Pauliina Meskanen, and Dr. Fox Thorpe, Calectra, explore how thermal energy storage can convert low-cost, off-peak renewable electricity into affordable process heat, unlocking new economic and decarbonisation opportunities for cement producers.

CONDITION MONITORING & PREDICTIVE MAINTENANCE

The Connected Conveyor Code
Elise Morse, Regal Rexnord, explores how connected conveyor technologies, predictive maintenance, and integrated reliability strategies are helping cement producers reduce downtime and turn data into actionable performance gains.

LOW CARBON CEMENT

Building Better With Blended Cement
CalPortland outlines how natural pozzolan-based blended cements can reduce clinker content while maintaining concrete performance and durability across large-scale infrastructure projects.

Plant Potential Unlocked
Daniel Kopp and David Gersholowitz, Queens Carbon, explain how plant-compatible technologies and engineered cementitious materials can help producers scale lower-carbon cement production using existing infrastructure.

The Business Case For Low Carbon Cement
Ryan Gilliam, Fortera, explores the business case for scaling low-carbon cement and explains why commercial execution will define the next phase of cement decarbonisation.
