The present study explores a cost-effective method for using activated ground granulated blast furnace slag (GGBFS) and silica fume (SF) as cement substitutes. Instead of activating them with expensive alkali solutions, the employs industrial-grade powdered sodium aluminate (SA) hydrated lime (HL) activators, reducing expenses by about 94.5% compared to their corresponding analytical-grade counterparts. Herein, exclusivity is depicted less pure chemicals rather than relying on reagents 99%...
The effect of size on strength fiber-reinforced polymer (FRP)-confined cylindrical concrete columns is studied. specimens studied are self-similar, i.e., all column dimensions as well FRP wrap thickness scaled proportionately with specimen size. Unlike many previous studies, a significant found in large specimens. A simple analytical model used to explain the observed behavior. mode failure seen be critical determining effect. Whereas cylinders small fail because rupture induced by plastic...
The effect of laminate thickness on crack pattern, mode failure, and strength shear deficient reinforced concrete (RC) T-beams wrapped with glass fiber polymer (GFRP) laminates was studied experimentally numerically. Eight specimens 2.5 m span, designed to fail in shear, were tested for two point static loading. Displacements, strains, pattern monitored. failure found depend the pattern. For U wraps, increasing (FRP) resulted reduced web cracking increased near free edge laminate.
In this paper the failure of a three layer system comprising concrete column, an intermediate epoxy layer, and fiber-reinforced polymer (FRP) confinement is investigated. We perform series numerical experiments to investigate how loads ultimate strains axially loaded plain cement (PCC) reinforced (RCC) columns change with type bond between FRP. Three types interfacial behavior are considered: rigid, cohesive compliant, unbonded contact. An idealized spring model for resultant stiffness used...
Summary The effect of heterogeneity in meso level geometric and material properties on tensile strength size split cylinder specimens is investigated. Critical parameters are identified by studying their influence the evolution fracture process zone. A statistical analysis used to account for dependencies between parameters. reversal effect, important field specimens, observed certain geometries. Meso explanations this proposed, geometries likely show such a identified. For moderately sized...
