The Possibilities for Using Ash and Slag Waste in Civil Engineering

Applied Sciences
This research aimed to improve our understanding of how ash and slag waste (ASW) could be used in civil engineering. The present study concentrated on the utilisation of bottom sand (ASW) in cement composites as a replacement for a part of aggregate and the evaluation of the pozzolanic properties of the material.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.
