ABSTRACT PERFORMANCE CHARACTERIZATION OF HIGH PERFORMANCE CONCRETES UNDER FIRE CONDITIONS By
PERFORMANCE CHARACTERIZATION OF HIGH PERFORMANCE CONCRETES UNDER FIRE CONDITIONS By Wasim Khaliq (Advisor: Prof. Venkatesh Kodur) Monday, April 30, 2012, 1:00 pm CEE Conference Room (EB 3546D) In recent years, high performance concretes (HPC) are finding increasing applications in buildings and infrastructure due to numerous advantages, such as higher strength and durability, these HPC offer ov...
متن کاملScaling resistance of high performance concretes containing a small portion of pre-wetted lightweight fine aggregate
The subject of the investigation was the influence of pre-wetted lightweight aggregate on damage of the concrete surface due to cyclic freezing and thawing in the presence of de-icing salts tested according to the Swedish Standard SS 13 72 44 (the Borås method). Six series of concrete specimens were made with the same water/binder (w/b) ratio 0.32, cement volume 400 kg/m and content of superpla...
متن کاملLowering the global warming impact of bridge rehabilitations by using Ultra High Performance Fibre Reinforced Concretes
Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) is charact erized by a unique combination of extremely low permeability, high strength and deformability. Extensive R&D works and applications over the last 10 years have demonstrated that cast on site UHPFRC is a fast, efficient and price competitive method for the repair/re habilitation of existing structures. More recently, an origina...
متن کاملCorrosion Resistance Performance of Fly Ash Blended Cement Concretes
Durability of reinforced concrete with respect to corrosion of reinforcement is one of the major aspects to be considered in the management of civil infrastructure systems. An accelerated laboratory test method developed at SERC where the concrete specimen containing rebar is subjected to polarization under a constant voltage in a sodium chloride solution. It is found that the current response ...
متن کاملEvaluation of sustainable high-volume fly ash concretes
This article presents experimental research work oriented toward developing practical design tools for industrial application, and illustrates the potential benefits of the synergistic effect of an ASTM C 618 Class F fly ash (FA) and a high-range polycarboxylate superplasticizer (SP) in the production of conventional concrete. The different concretes considered in this study were produced with ...
