A November 2013 CSHub research profile letter, “Early hydration: A local business,” charts calorimetry (heat measurement) curves from tricalcium silicate paste experiments—with specimens of three particle size distributions (PSD)—to support a proposed model of microstructure-based kinetics. It suggests a “reaction zone” extending a few micrometers in from the cement particle surface, and can reconcile longtime observations on PSD and water/cement ratio.
Combining a restored concrete slab and existing timber construction, with new steel and clay masonry, the $1.7-million, 7,000-sq.-ft. Arts Plaza is a raw, open-air space for the arts at Lafayette College in Easton, Pa. The project transformed a former auto-repair facility into a dynamic outdoor teaching space that responds to its natural environment and built context. Designed as an outdoor black box theater, the plaza hosts a wide variety of planned and spontaneous artistic endeavors, including performance art, visual art exhibits, and small group musical performances.
