A Comparison between Natural Pozzolana and Fly Ash Replacements on the Mechanical Properties of Concrete
(
Qatar University Press
, 2023 , Conference Paper)
This study investigates the effect of Natural Pozzolana (NP) and Fly Ash (FA) substitutes on concrete's mechanical and microstructural properties. Mixes containing 10 - 50 % cement substitute ratios were prepared and tested ...
Bond Performance of Near-Surface Mounted BFRP Bars to Concrete
(
Qatar University Press
, 2023 , Conference Paper)
This paper presents the test results of a study on the bond performance of near-surface mounted (NSM) basalt fiber reinforced polymer (BFRP) bars to concrete. Twelve C-shape concrete specimens were tested under direct ...
Parametric Optimization of RC Beams Strengthened with FRCM Using FE Modelling and Response Surface Methodology
(
Qatar University Press
, 2023 , Conference Paper)
This study focuses on the numerical and statistical analyses to predict the mid-span moment capacity of RC beams strengthened with fabric reinforcement cementitious mortar (FRCM) laminate. A finite element model (FEM) has ...
