Construction materials from the internal ducts of Aqua Traiana, a still operative Roman aqueduct built in 109 AD to supply water Rome, were characterized by optical microscopy (OM), scanning electron (SEM-EDS), X-ray powder diffraction (XRPD) and microprobe analysis (EMPA). Petrographic XRPD revealed that mortar aggregates are compatible with Vitruvius’ harena fossicia allowed distinction origi...

Lightweight concrete (LWC) is used in the construction of partition and panel walls framed structures because it reduces dead load acting on structure. Rubberized lightweight aggregate made by using waste rubber tyre chips as a partial replacement coarse which increases ductility, toughness minimizes impact effect concrete. The presence content decreases compressive strength bond strength, affe...
