Abstract Reinforced concrete as the most important construction material suffers from long-term deterioration due to different exposure conditions. Fire attack is a critical condition it can lead complete collapse of structure. On other hand, repair and strengthening existing structures have become necessary both technically financially. Moreover, since high-performance concretes (HPCs) are ext...

This paper presents a comparison of the properties of concrete slabs when two types of fibres are added. One specimen had no fibres and acted as a control specimen. The remaining four specimens had steel and polypropylene fibres added in the volumetric ratio of 0.5% and 1.0%. The dimensions of the slab specimens were 820×820×80 mm and were supported by four rollers at their edges. A displacemen...
