Fire resistance of corroded structural concrete

Unknown Date (has links)
One of the major causes of structural repairs worldwide is the corrosion of reinforced concrete structures, such as residential buildings and piers, which are exposed to harsh marine environments. This investigation aims to provide experimental evidence of the fire resistance of corroded high strength reinforced concrete. For this, 14 reinforced concrete beams of three different concrete mix designs (different strengths) were prepared along with concrete cylinders for compression strength testing (ASTM C39). After proper moist curing, all beams were corroded, in two phases, with impressed current, then “crack scored ”for corrosion evaluation, after which half were exposed to fire, also in two phases, following the ASTM E-119-12 time-temperature curve, using a gas kiln. The fire damage was evaluated and compared between phases by using Ultrasonic Pulse Velocity technology. Finally, all specimens were tested for flexural strength by using the third-point loading method (ASTM C78) and the effects of fire on the corroded beams were analyzed according to the level of corrosion. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2014. / FAU Electronic Theses and Dissertations Collection

Synthesis and Flame Retardant Studies of Bromoester of 2,4-Pentadienoic Acid

Ghane, Hessam 01 January 1978 (has links) (PDF)
The synthesis and fire retardancy of several bromoesters of 2,4-pentadienoic acid were investigated. The synthesis of 2,4-pentadienoic acid was accomplished by liquid phase reaction of acrolein and malonic acid in the presence of pyridine. The conversion of the acid to bromoesters was performed by two different procedures. In the first procedure, the corresponding acid chloride was prepared from the acid via reaction with SOCl2 in the presence of powdered (3A°) molecular sieves. The molecular sieves serve as an internal trap for by-product HC1 and inhibit the competing polymerization reaction of the acid chloride. Reaction of the acid chloride with various alcohols provided the unsaturated esters. The final step in the first procedure is total bromination of the unsaturated esters. The second procedure involved bromination of 2,4-pentadienoic acid and followed by reaction of the bromo acid with SOCl₂ to produce the corresponding bromo acid chloride. Reaction of the brominated acid chloride with alcohol provided the corresponding brominated esters. A simple laboratory test was developed to measure and compare the flame retardancy of the bromoesters.

Parametric studies on the temperature dependent behaviour of steel structures within a fire context.

Govender, Stanton Wesley. January 2012 (has links)
The mechanical and material properties of structural steel at elevated temperatures play an important role in structural fire design. The South African 350W and S355 structural steels are common in building structures with S355 slowly replacing the older 350W. The cost and feasibility of full scale fire tests are some of the causes for the lack of experimental data on the behaviour of steel structures when exposed to fire. Therefore excessively conservative design codes based on isolated laboratory experiments are used in practice which leads to increased material costs. Another area of concern with respect to building safety is the reusability of structural steels post fire exposure, which is not effectively addressed within these codes. This study aims to establish greater insight into structural fire design and simulation on which further research can be built. Experimental programs on the temperature dependent behaviour of these steel members loaded axially are conducted and compared with theory and the Eurocode 3 standard [1]. The reusability of steel exposed to fire and after being cooled down is investigated and compared to the findings by Outinen [2]. Further testing on material to determine the relationship between remaining life and hardness degradation after cooling down was conducted. Experimental data from various external studies are used to develop novel computer models using the finite element analysis software, SimXpert [3]. These are verified against the original data and compared to existing design codes. A parametric approach is used with these models to demonstrate the advantages of computer simulations in structural fire design. Different cross sections and slenderness ratios are evaluated for their susceptibility to buckling at elevated temperatures. The results of this study show that as temperature and exposure time increase the integrity of steel members decrease. The current design codes accurately predict the behaviour of isolated specimens but lack data on real situations where the specimen is part of a complex structure. It was found that steel members can be reused if their exposure temperature does not exceed 700°C, after which their strength can reduce to 90%. This temperature dependant behaviour was successfully modelled using basic computer simulations and then demonstrated the ease in which they can be used in place of experimental regimes. The parametric advantages of these simulations were demonstrated by predicting the effects of slenderness ratios and geometry cross sections on the buckling behaviour. / Thesis (M.Sc.)-University of KwaZulu-Natal, Durban, 2012.
