Damage assessment of concrete structures exposed to fire [PDF]
, 2013 During a fire, concrete structures behave in most cases very well. It could therefore be of economic interest to repair the damaged structures, as costs for demolition and rebuilding can be avoided and the building can be reused faster.

Assessing the Rebound Hammer Test for Rammed Earth Material [PDF]
Sustainability, 2017 Rammed-earth (RE) is a construction material manufactured from the soil. The soil is compacted at its optimum water content, inside a formwork to build a monolithic wall. RE material is attracting renewed interest throughout the world thanks to its sustainable characteristics: low embodied energy, substantial thermal inertia, and natural regulator of ...

A new technique for non-destructive field measurement of rock-surface strength: an application of the Equotip hardness tester to weathering studies [PDF]
, 2007 Tafone-like depressions have developed on the Aoshima sandstone blocks used for a masonry bridge pier in the coastal spray zone. A thin layer of partial granular disintegration was found on the surface in depressions.
