Craftsmanship, gamesmanship prevail at Solomon Colors Fair

Some of the top artisans, cement masons and contractors who have helped drive concrete finishes and elements deeper into architecture, hardscapes and interiors over the past two decades convened last month for the Solomon Colors 2018 Decorative Concrete Fair. Staged near the host’s Springfield, Ill., headquarters, the three-day event spanned pattern stamping of integrally colored mixes; slab staining and finishing techniques; vertical surface carving and molding; and, countertop and outdoor fire table casting—all showcasing namesake, Brickform and Ultra Fiber brands.

Petrographers offer quick study on pinpointing slab, structure defects

A new white paper shows how petrographic examination identifies the root cause of common deficiencies and degradation mechanisms in hardened concrete, from low compressive strength, surface scaling or spalling to cracking and alkali-aggregate or chemical reactions. Available free of charge, “The Concreting Process and Petrographic Examination,” is primarily for cast-in-place concrete but offers content applicable to precast as well, and suits engineers, architects, contractors, producers, agencies and building owners.

NPCA extends product-specific certification to water, wastewater tanks

The National Precast Concrete Association takes quality control and validation to the next level with a new product-focused certification for water and wastewater tanks. While its Plant Certification program has traditionally centered on precast concrete production processes candidate operations must abide, the just-launched Optional Product Listing for Water and Wastewater Tanks Program describes specific product models, plus design and performance criteria to obtain certification. Like other association programs, the new offering enlists independent third-party engineering firms accredited to ISO/IEC 17020:2012 for Plant Inspection.

BASF Admixture Systems panel probes mixing concrete in space

For many years engineers have dreamed about building habitable structures on the Moon or Mars. Those structures will have to be sturdy and stable, which begs the question, why not use concrete? But can ready mixed concrete be successfully formulated in the unique atmospheric conditions of the lunar or Martian surface? That is a question scientists are seeking to answer. And recently completed experiments conducted on the International Space Station (ISS) may bring us closer to that answer.

Oldcastle retention system sees green light from key agency

Oldcastle Infrastructure (formerly Oldcastle Precast, note companion item) recently announced that its BioMod System received Washington State Department of Ecology equivalency approval as a stormwater bioretention planter or planter box. By granting “functional equivalency,” the agency affirms that the BioMod Modular Bioretention System does not need to go through its Technology Assessment Protocol — Ecology (TAPE) program for approval, and may be designed using the same standards and criteria as any non-proprietary bioretention planter or planter box.
