Life-cycle perspective backs report on critical issues in building practices

IMAGE

A new report from the Massachusetts Institute of Technology-hosted Concrete Sustainability Hub (CSHub), Critical Issues When Comparing Whole Building and Building Product Environmental Performance, addresses key concepts in quantifying the environmental impact of buildings and products comprising them. It also makes recommendations for current and future building practices using life cycle assessment (LCA), and offers suggestions for research to advance future study and practice.

CSHub at MIT develops hazard mitigation metric

CSHub at MIT develops hazard mitigation metric

The Concrete Sustainability Hub at Massachusetts Institute of Technology has developed Break Even Mitigation Percent (BEMP), a new tool to estimate the cost of weather hazards on a building. In a new research brief, “A break-even hazard mitigation metric,” CSHub staff finds that a $10 million non-engineered wood building is expected to face more than half a million dollars in hazard related damages over 50 years, while a $10 million engineered concrete building is expected to face only $165,000 over the same period.

MIT researchers: Marine species suggest blueprints for better concrete structures

In a project funded by outside parties and independent of the Concrete Sustainability Hub, Massachusetts Institute of Technology researchers are seeking to redesign concrete by following nature’s blueprints, contrasting cement paste with the structure and properties of bones, shells, and deep sea sponges. As they observe in the current Construction and Building Materials paper, “Roadmap across the mesoscale for durable and sustainable cement paste—A bioinspired approach,”such biological materials are exceptionally strong and durable, thanks in part to their precise assembly of structures at multiple length scales, from the molecular to the macro, or visible, level.

Sizing up nano-scale materials

For the third year in a row, we visit a pavement project VCNA Prairie Material helped convert from all asphalt to partial (base slab) or 100-percent roller compacted concrete. More than a routine switch, the Maryhill Cemetery maintenance shop (pages 28-31) marks the commercial debut of RCC Surface Pro, a silica agent emanating from the field of nanotechnology, where particles are measured in billionths of a meter.

Borrowing from a ‘rigidity theory’ that has led Corning Inc. engineers to the high performance Gorilla Glass—its toughness in thin sections equal to smartphone and laptop computer screens—the Concrete Sustainability Hub is studying potential portland cement reformulation aimed at higher fracture resistance than current ASTM C 150 product.
