A five-route roadmap details how European Cement Association members and customers can reduce their industry’s carbon dioxide emissions from a 1990 level of 170 million metric tons to 34 million metric tons by 2050. Routes under cement sector control are Resource Efficiency, Energy Efficiency, plus Carbon Sequestration and Reuse; two others, Product Efficiency and Downstream, target low-carbon concretes, smart buildings and infrastructure, concrete recycling and sustainable construction.

South Korea’s Ssangyong Cement Industrial Co. Ltd. enlisted its packaging supplier to produce an 88-lb. (40 kg) cement bag equal to rough handling en route to Antarctica research stations. Taemyung Industrial Co. Ltd. turned to two-ply Mondi Kraft Advantage sack, exhibiting what Vienna-based manufacturer Mondi Group notes is high tensile energy absorption and porosity. The product’s capacity to replace three-ply alternatives nets material savings exceeding 25 percent.

ASTM C01 examines alkali activated binder versus natural pozzolan testing

ASTM International Committee C01 on Cement is developing a standard to help create data for comparing the compressive strength of alkali activated fly ash and natural pozzolans. ASTM WK42602, Test Method for Compressive Strength of Alkali Activated Coal Fly Ash and Raw or Calcined Natural Pozzolan Cement Mortars (Using 2-in. or [50 mm] Cube Specimens), is under the jurisdiction of Subcommittee C01.13 on Special Cements.

NCMA gauges thermal loading effect on CMU structural integrity

Details: Published: Thursday, 26 September 2013 12:24; Written by CP Staff

National Concrete Masonry Association staff is working on simplified fire loading finite element models, capturing the thermal effects of applied heat to concrete masonry units. The rudimentary models are being used to calibrate modeling/results to accurately capture the expected heat transfer response through individual units. Results will be extrapolated to larger wall assemblies, where simulated full-scale fire testing will be modeled and compared against existing physical test reports.
