This review aims to provide an insight into concrete pavement repair materials by gathering the relevant research outcomes and specifications. It provides a systematic literature that focuses on types of cementitious material. In general, conventional can be divided 4 categories: ultra-rapid, rapid, accelerated, normal strength gain. The mechanical durability properties materials, i.e., calcium sulphoaluminate-based, aluminate-based, polymer-modified concrete, ordinary Portland cement-based...

Sometimes civil engineering infrastructures have been constructed in hot and cold weathering regions such as desert areas. In situations, the concrete is not only smashed by processes but also spoiled shrinkage cracking. Therefore, this study intends to examine influence of heat–cool cycles on high-strength comprising various fibers, natural date palm, polypropylene, steel their different volume percentages. The most popular technique for improving structural behavior fiber insertion. Fibers...

Nowadays, the use of near surface mounted (NSM) technique strengthening reinforced concrete (RC) structural members is going very popular. The failure modes NSM strengthened beams have been shown to be largely due premature such as cover separation. In this study, CFRP U-wrap end anchorage with fabrics was used eliminate separation failure. A total eight RC rectangular beam specimens 125 mm width, 250 depth, and 2300 length were tested. One specimen kept unstrengthened a reference; three...

This paper presents the experimental behavior of reinforcement concrete beams strengthened with near surface mounted (NSM) steel bar.Several researchers have used NSM fiber reinforced polymer (FPR) bar or strip for strengthening beams.Though FRP has a number advantages like high strength, light weight and corrosion resistance it doesn't show any ductile behavior, still highly expensive not easily available in market.On other hand, is less expensive, readily market shows good ductility.In...

Reinforced concrete (RC) structures necessitate strengthening for various reasons. These include ageing, deterioration of materials due to environmental effects, trivial initial design and construction, deficiency maintenance, the advancement loads, functional changes. RC with carbon fiber reinforced polymer (CFRP) has been used extensively during last few decades their advantages over steel reinforcement.
