Balancing the Concrete and the Abstract - Educational ...

Research shows that presenting knowledge in both concrete and abstract terms is far more powerful than doing either one in isolation (Pashler et al., 2007). This is particularly true in math and science classrooms. For example, a 2003 study showed the benefits of initially presenting concepts in a concrete fashion and then, over time ...

10 steps to reducing embodied carbon - AIA

Work with your structural engineers to design lower carbon concrete mixes by using fly ash, slag, calcined clays, or even lower-strength concrete where feasible. Though access to these materials varies across the country, with an increasing number of options there is almost always something that can reduce the carbon footprint of your concrete mix.

Pulse Velocity - an overview ScienceDirect Topics

The ultrasonic pulse velocity (UPV) measurement can be utilized for the determination of concrete uniformity, cracks or voids' presence, changes in properties with time. As the amount of DOTP in the concrete increases, the ultrasonic pulse velocity of the concrete decreases. It can be said that this is due to the porous structure of DOTP-reinforced concrete (Şimşek et al., 2018).
