Cantilever Beam Metastructure for Passive Broadband Vibration Suppression
(
Qatar Univesrity Press
, 2020 , Conference Paper)
This paper presents a beam structure of a new metamaterial-inspired dynamic vibration
attenuation system. The proposed experimental research presents a designed cantilevered
zigzag structure that can have natural frequency ...
Dune Sand Mortar Effects on Deflections of Repaired Steel Bars-Reinforced Concrete Beams
(
Qatar Univesrity Press
, 2020 , Conference Paper)
This paper presents theoretical and experimental investigations to analyze the flexural
behavior of reinforced concrete beams repaired with mortars based on dune sands. The
beams supposedly damaged were repaired using ...

A new line of research is presented in this study where sodium acetate is used as a
protective material for concrete. A newly developed freeze-thaw method that depends
on the alteration of temperature and humidity is ...
Mechanical Properties of Concrete Made with Electric Wires, Steel Fibers, Basalt Fibers and Polypropylene Fibers
(
Qatar Univesrity Press
, 2020 , Conference Paper)
An experimental program is conducted in this research to investigate the mechanical
properties of concrete made with electric wires, steel fibers, basalt fibers, and
polypropylene fibers. Fibers are added to the concrete ...
Utilizing Steel Slag in the Removal of Suspended Solids from Dewatered Construction Water
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Construction dewatering is an operation used to remove shallow groundwater that
infiltrates construction sites. After recovering this water from the construction sites, the
water is either discharged to the sea, injected ...
