When compressive strength tests of laboratory-cured cylinders fail to meet the specified acceptance criteria, core tests are commonly used to verify the strength and to obtain acceptance of the ...

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 ...

The conversion of iron tailings, a mining solid waste, into conductive concrete aligns with green engineering and supports the development of intelligent construction materials. This study employed a ...

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 ...

This study presents a transformative advancement in civil engineering by integrating artificial intelligence with infrastructure sensing to redefine concrete structures testing and monitoring.

American Association of State Highway and Transportation Officials’ Committee on Materials and Pavements approves Purdue-invented method as a national standard for estimating concrete strength WEST ...

New analysis explains how outdated concrete testing slows road and bridge projects, and what Iowa's specification ...

Drexel University engineers have shown that a concrete mix designed to gently warm itself in cold weather can cut damaging freeze-thaw cycles outdoors, pointing to longer-lasting pavements for cold ...

Ultra-high-performance concrete (UHPC) is rapidly emerging as a premier material for precast concrete construction. First introduced as “reactive powder concrete” in the early 1990s, this material has ...

As infrastructure ages, one question shapes the future of cities: How do we know the materials we build with will last? Subscribe to our newsletter for the latest sci-tech news updates. At the ...
