Concrete Studies 2017

Abstract

The first study is “Comparison of Fire Resistance of RC Slabs Determined according to Different Methods“. We construct our buildings and facilities to last 50, 100 or even 200 years. There is a high probability that fire will eventually occur during the service life of practically every structure. Fire can happen anytime and anywhere. This study explores fire resistance of RC slabs that are the most sensitive concrete elements in fire situation. We compared the results of determination of fire resistance according to four different methods. We got some conclusions, but also opened an area for new research on fire resistance of some other concrete elements. Concrete is principal construction material in Bosnia and Herzegovina. It is very common. However, concrete of high compression strength is almost unknown in Bosnia and Herzegovina. The study of “High-Strength Concrete (HSC) and Possibilities for Production in Bosnia and Herzegovina“ discusses the recent history, advantages and disadvantages, application and benefits of it, as well as the constituent materials, mix design and proportioning and properties of high strength concrete. Experimental part of this study proves that it is feasible to produce highstrength concrete of slightly modified ordinary concrete mix improved by domestic admixtures and additives at minimal cost. This study aims to encourage concrete factories to produce it and engineers to apply it in their designs and actual construction
