This paper presents the results of 12 tests on small-scale reinforced concrete beams strengthened in flexure with a single NSM carbon FRP bar. The used bar is novel commercial high values glass transition Tg and decomposition Td temperature to improve performance strengthening system at elevated temperature. bonded using cementitious grout rather than an epoxy adhesive. Flexural were performed ...

Expansion of the offshore wind industry in seismically active areas has raised concerns regarding structural integrity turbines under earthquake loading. This paper details a 3D finite element study to investigate behaviour structure, and particular transition piece (TP), seismic loads. The work focuses on equivalent grouted connection TP-less designs, selected as promising design solutions for...

• A comparison of mechanochemically activated and conventionally geopolymer grouts. The influence slag/fly ash ratio sodium hydroxide molarity in grouts behavior. Mechanochemical activation processes effect on rheological fresh characteristics. Effect mechanochemical mechanism mechanical properties grout. In this research, a (MG) grout is adopted to activate slag, fly ash, hydroxide, silicate b...

C ommercially available fiberbased reinforcement for concrete is made of carbon, aramid, or glass filament fibers impregnated in a resin. Some aramid fiber reinforcement consists of aramid filaments without a resin matrix. For general applications, the most important feature of fiber-based reinforcement is its resistance to corrosion, which makes it ideal for reinforcing concrete exposed to hig...

Several studies on different techniques can be found retrofitting existing unreinforced masonry (URM) walls using varieties of materials ranging from reinforced plaster, grout and epoxy injectio...

Silica sol, i.e., colloidal SiO2, may be used as a low-pH injection grout for very fine fractures in the construction of deep geological repositories for radioactive waste in Sweden and in Finland. If the bentonite barrier encounters SiO2-colloid particles under conditions favorable for aggregation, there is concern that it will modify the bentonite barrier at the bentonite/bedrock interface. I...
