Results that are obtained from concrete specimens during laying of concrete may not actually represent the concrete strength in the structure. In situ NDT (non-destructive testing) at several ...

Although failure of material is not the only reason for bridge failures, it is a vital step for choosing the correct materials, the analysis of bridge design, and construction testing. Bridge members ...

This prompted the researchers to test whether desert sand could be repurposed using a manufacturing approach that does not rely on conventional cement binding. During a series of trials, the ...

1. Obtain a representative concrete sample from the revolving drum truck mixer. 2. Using a scoop, place concrete in the cylinder molds. For 6 by 12 inch molds, place in three equal layers (1/3 volume ...

Explore the future of construction with 3D concrete printing. Discover its viability for load-bearing components and ...

The 3D-printed concrete barracks requires a crew of only three trained workers during construction, though for continuous printing, about three shifts of crews are required to avoid burnout. Photo by ...

WEST LAFAYETTE, Ind. – Transitioning to clean wind energy could become more cost-efficient as Purdue University researchers test a new technology created by an international startup to anchor offshore ...

Concrete suppliers and contractors are sometimes accused of producing or placing low-strength concrete. While low-strength concrete does occasionally occur, many times reported cylinder strengths are ...
