| ===Construction and geotechnical testing===
| |
| From construction materials such as concrete and asphalt to construction site substrates like clay and rock, the proper quality and characterization of construction and engineering materials is critical to a construction project's long-term success. The importance of perfecting and using quality construction materials dates back millennia, for example to the Romans and their refinement of concrete recipes and production using pozzolanic and quicklime materials.<ref name="ChandlerRiddle23">{{cite web |url=https://news.mit.edu/2023/roman-concrete-durability-lime-casts-0106 |title=Riddle solved: Why was Roman concrete so durable? |author=Chandler, D.L. |work=MIT News |publisher=Massachusetts Institute of Technology |date=06 January 2023 |accessdate=15 November 2023}}</ref> Even today, we learn that sands such as desert sand are inadequate for direct use in modern concrete due to their negative contribution to compressive strength of the concrete.<ref>{{Cite journal |last=Akhtar |first=Mohammad Nadeem |last2=Jameel |first2=Mohammed |last3=Ibrahim |first3=Zainah |last4=Muhamad Bunnori |first4=N. |last5=Bani-Hani |first5=Khaldoon A. |date=2023-06 |title=Development of sustainable modified sand concrete: An experimental study |url=https://linkinghub.elsevier.com/retrieve/pii/S2090447923002204 |journal=Ain Shams Engineering Journal |language=en |pages=102331 |doi=10.1016/j.asej.2023.102331}}</ref>
