Foundation groups inject rheology into revised tremie concrete practice

The Deep Foundations Institute (DFI) and European Federation of Foundation Contractors (EFFC) have released a free download of their recent Best Practice Guide to Tremie Concrete for Deep Foundations. The publication stems from initial efforts of the joint DFI and EFFC Concrete Task Group, established in 2014 to study common problems in drilled shafts and diaphragm walls constructed using tremie methods.

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.
