Alternative SCM, industrial mineral blend catapults C-S-H formation

California-based construction materials specialist Surface Tech is commercializing an alternative supplementary cementitious material (ASCM) whose requisite chemical profile (silicon dioxide + aluminum oxide + iron oxide content > 75 percent) belies binder-optimizing performance potential exceeding that of leading SCM. While fly ash, GGBF slag and silica fume tend toward dosages starting at 10 percent by weight of portland cement, Juno XP has exhibited marked strength development characteristics at 2.5 percent and 5 percent when measured against portland cement controls—particularly at seven- and 28-day cylinder breaks.

Next generation Oshkosh S-Series embodies mechanical to digital shift

As peak 2019 construction season approached, Wisconsin-based Oshkosh Corporation briefly assembled ready mixed concrete producers from across the industry to showcase and open the order book for the new namesake S-Series front discharge mixer truck. President and CEO Wilson Jones framed the vehicle in terms of an overall diesel-powered equipment migration from mechanical to digital, Internet of Things-heavy operation. He and senior business leaders underscored TCO, or total cost of ownership, as the driving force behind the new S-Series design and specs. Measured against a legacy model introduced 25 years ago and upgraded in 1999, they outlined the truck’s features and performance potential:

Analyzing maintenance and repair data keeps fleet managers in check

Over the last 12 to 24 months, it seems as though topics such as autonomous driving and electronic logging device mandates have flooded the headlines for the transportation industry. And deservedly so: they are no doubt topical, important issues. However, in running your fleet day-to-day, understanding the evolution of maintenance and repair (M&R) issues and costs continue to be on top of the level of importance.

How to measure free or surface aggregate moisture

The moisture meter you own or buy will define how you measure your aggregate moisture levels. While most sensors measure bulk moisture, some measure only surface moisture. In either case, though, they can be calibrated to read surface or free moisture. This is the moisture that reacts with the cement in the mix and, therefore, the only moisture you need to worry about.
