Comparison of Non-Destructive and Destructive

Equations were obtained by statistical analysis to analyses concrete’s compressive strength on site. Correlation charts were plotted, and regression equations were listed (Table 2). The results showed that using more than one NDT provided a better correlation and lead to predictable evaluation of concrete’s strength.

What is Bacterial Concrete or Self-Healing Concrete

Bacterial Concrete or Self-Healing Concrete (SHC) is a modern approach in civil engineering for repair purpose. As the name suggests, this type of concrete can heal itself when cracks appear after curing and hardening. In this article, I will discuss it’s brief history, mechanism, production, advantages, disadvantages and some other aspects.
