Abstract null null The current paper aims to propose a novel epoxy resin bonding agent for improving the bonding strength of epoxy resin coating systems. These kinds of systems are mainly employed during the repair and maintenance of existing cement-based structures, especially concrete floors. The paper presents the results of a series of tests of epoxy resin coatings, in which the matrix of the bonding agent made of epoxy resin is modified with the addition of coconut fibers. Pull-off strength...

Abstract null null In order to study the reversibility between aging and rejuvenation of modified asphalt binder, a kind of virgin asphalt was selected, and then three kinds of modified asphalt were prepared based on this virgin asphalt. The short-term and long-term aging tests were carried out for the four asphalts. Then three kinds of rejuvenation tests were carried out for the aged asphalt, including commercial rejuvenator, aromatic oil and warm mix rejuvenator. Dynamic shear rheometer (DSR) ...

Corrosion of steel reinforcement is the major cause of deterioration in reinforced concrete structures. Strengthening of concrete structures has been widely studied. However, most research was conducted on sound structures without considering the effects of corrosion. This paper presents an experimental study of the feasibility of using externally bonded FRP laminates combined with U-jackets, applied directly without repairing the deteriorated concrete cover, to strengthen beams with corroded re...

Abstract null null The early-age mechanical properties of cement asphalt mortar (CAM) directly influence the process and quality of non-ballasted track during construction. In order to shorten the long curing period of CAM during the construction of non-ballasted track and accelerate the procedure, nano-SiO2 (NS) and nano-TiO2 (NT) were added to CAM in this study; this also improved the age-related mechanical properties of CAM, especially at early ages. Compressive strength tests were conducted ...

Abstract null null In this study, the parameters affecting Marsh-funnel flow time and mini-slump of the paste mixtures were determined through experimental and modelling studies. Marsh-funnel flow times were modelled through artificial intelligence and regression methods. A novel model was used to train the coefficients of artificial neural networks (ANN) with the Teaching-Learning Based Artificial Bee Colony (TLABC) Algorithm. Accuracy of this method was investigated through ANN-Back Propagatio...

Abstract null null Near-surface voids on a cement concrete sample were successfully sealed by applying a metal-ethylenediaminetetraacetic (EDTA) acid complex solution, followed by treatment with high-heat hydrogen/oxygen (H2-O2) coupled flame. The calcium aluminates used for sealing were fabricated on cement substrates using calcium-aluminate (Ca,Al)-EDTA solutions prepared at various elemental ratios. The sealing effects were investigated through crystal & pore structure analysis and water perm...

Abstract null null The hydration process and products of polymer-modified cement determine its pore structure and mechanical properties. However, relatively few studies have systematically studied the hydration behavior, microstructure and mechanical properties of waterborne epoxy resin (WER)-modified cement blends. This study aims to investigate the influence of the WER content and curing temperature on the early hydration process and hydration product evolution of cement paste. Moreover, the r...

Abstract null null Laminated bamboo is growing in potential as a novel construction material due to the need to lower the carbon impact of the built environment. The material utilises raw bamboo in an engineered composite to create a standardised prismatic section. The present study investigated the mechanical properties, as well as the performance under sustained load, of laminated bamboo sections which had undergone a secondary glue laminating process to facilitate the forming of curved profil...

Abstract null null The bond at fiber–matrix interface is considered as one of the most important factors influencing the performance of fiber reinforced cementitious composites (FRCC). To improve such bond, adding silica fume is considered as an effective and efficient method. In modern FRCC, CaCO3 (calcium carbonate) whisker and basalt fibers witnessed increasing popularity due to their effectiveness in improving mechanical performance at multi-scales. However, systematic research still lacks f...

Abstract null null The main objective of this work is to use the oil to improve the low- and intermediate- temperature performance of styrene–butadienestyrene (SBS) modified asphalt, and how long the benefits of adding oils can stay (aging property) was also evaluated. In this study, one bio-oil and one re-refined engine oil bottom (REOB) were selected to blend with two types of SBS modified asphalt to prepare oil/SBS modified asphalt. The performance improvement, rheological and chemical evolut...
