RESEARCH ON THE DEVELOPMENT OF LOW-TEMPERATURE-RESISTANT FAST-CURING STRUCTURAL ADHESIVE AND STEEL PLATE STRENGTHENING CONCRETE BEAM FLEXURAL TEST Steel plate strengthening method is a common, efficient, and mature reinforcement method that utilizes structural adhesive to bond steel plates with concre......
Thus, they are often employed as primers and topcoats for large structures such as ships, bridges, and industrial plants and equipment. Some amine-epoxy formulations provide excellent adhesion to concrete and other cementitious materials and, therefore, are often employed in sealers, primers, ...
for instance, an average molecular weight of from 250 to 30000 g/mol, in particular from 1000 to 15000 g/mol, and/or preferably an average OH functionality in the range from 1.6 to 3. It is possible to use a combination of differently functional polyether polyols P, for example a combina...
Long-term durability of carbon reinforced concrete. An overview and experimental investigation. Appl. Sci. 2019, 9, 1651–1665. [Google Scholar] [CrossRef] Karbhari, V.M.; Abanilla, M.A. Design factors, reliability, and durability prediction of wet layup carbon/epoxy used in external ...
③ Pour the concrete mortar evenly into the steel ring, smooth it so that the thickness of the concrete sample is equal to the height of the steel ring, and cure for 28 days according to standard procedures. ④ Take the concrete sample out of the steel ring, and select the one with ...
This study analyzes the mechanical properties of high ductility concrete (HDC) under different ambient temperatures to provide a parameter basis for the design of HDC bridge deck link slabs. Five temperatures (−30, 0, 20, 40, and 60 °C) were designed to investigate the compressive, tensile...
To create Wöhler curves for concrete, pressure-swell fatigue tests are generally carried out. High frequencies are used so that the tests allow many load changes in a short time. In comparison to normal strength concrete, however, in the case of UHPC and high performance concrete (HPC) the...
