By Mauro Nogarin The cement industry in the main Latin American countries has stabilized, reaching in most cases the production levels of 2019. However, in Brazil and Mexico the unfavorable economic situation has led to an increase in the prices of construction has materials to such an extent that it has slowed down domestic demand. Unlike the situation in Peru,…
Read MoreA new ASTM International paper presents results of a National Concrete Masonry Association (NCMA) Education and Research Foundation investigation quantifying the amount and rate that machine-molded concrete products absorb and permanently lock up atmospheric carbon dioxide. “Conceptual Test Protocols for Measuring Carbon Sequestration of Manufactured Dry-Cast Concrete Products” covers lab work undertaken to develop and refine procedures that deliver repeatable,…

As The Use Of Alternative Fuels Grows, So Too The Challenges They Pose To Equipment And Process. by Jonathan Rowland Fossil fuels are often maligned for their carbon emissions. Yet they are not the world’s most successful energy source without reason. Fossil fuels pack a punch when it comes to calorific value and offer consistent chemical composition, moisture content and…
Read MoreTo Accommodate Expansion Movement Within Anchoring Systems, Vital Allowances Must Be Incorporated. Edited by Mark S. Kuhar Research shows that more than 40% of monolithic refractory failures are the result of improper anchor design and installation. Failures commonly attributed to the refractory component are instead often caused by shortcomings in the actual anchoring system. Like any material, refractories will expand…

Heidelberg Materials’ Edmonton, Canada, Plant Works To Implement CCUS Technology. By Kristin Dispenza The concept of carbon capture has been around for decades. While it has been implemented more widely in other sectors, such as coal-fired power generation, carbon capture, utilization and storage (CCUS) has not historically been applied to a cement kiln. There are significant differences and complexities between…
