This article presents the results of an experimental study on the flexural behavior of 4 specimens: 1 specimen of reinforced concrete (RC), 1 specimen strengthened with FRP sheets, and 02 specimens with the same height as the RC specimen but with a replacement of 3 cm of the protective concrete layer with a UHPC layer, either bonded or not bonded to the existing concrete, with or without the reinforcement of FRP sheets.

This paper presents the experimental results of structural responses of box beams using TRC. Ten specimens in two groups are designed with different longitudinal and transverse textile reinforcement ratios. All the specimens are loaded under a four-point bending test, in order to investigate both flexural and shear behaviour of TRC box beams.

This paper presents a computing module for a quick determination of flexural strength of fibre-reinforced concrete, plain concrete and hybrid cement composite. The hybrid cement composite consists of two layers of plain concrete and steel fibre-reinforced concrete. Both of these concretes are self-compacting ones.

The numerical results show a good correlation with the experimental results of the beam specimens, such as load-displacement curves, crack patterns, and failure modes. They allow confirming the capability of the developed FE model to predict the flexural performance of strengthened beams considering CFRP/concrete interfacial behavior.

This paper presentsa3D finite element modeling of the flexural behaviorof ultrahigh-performanceconcrete (UHPC).A four-point flexural teston a UHPCprestressed T girder is considered. The flexuralstrength and cracks pattern of girder are addressed. UHPC material is supposed to be homogeneous andisotropic material. It follows a nonlinear fracture model. The results are comparedwith experimentally captured measurementsand qualitatively discussed.

The paper investigates the flexural performance of reinforced concrete beams in which fly ash from Vinh Tan power station was used to replace original Portland cement in the proportions of 0%, 10%, 20% and 40% by weight. Twelve reinforced concrete beams with the dimensions of 100×150 mm in cross section and 1000mm in length were cast and cured in water.

In this study, GGBFS at different cement replacement ratios of 0%, 20%, 40% and 60% by weight were used in finegrained concrete. The ternary binders containing GGBFS and FA at cement replacement ratio of 60% by weight have also evaluated. Flexural and compressive strength test, rapid chloride permeability test and under-water abrasion test were performed. Experimental results show that the increase in concrete strength with GGBFS contents from 20% to 40% but at a higher period of maturity (56 days and more).

Textile-reinforced concrete (TRC) is a new composite material made of highstrength textiles embedded within fine grained concrete (FGC). The application of TRC leads to the design of thin and slender structures or for repairing and strengthening of existing structural members. Autoclaved aerated concrete (AAC) is an ultra-lightweight concrete, which can be combined with high strength TRC to form some kinds of precast curtain panels in construction.

Polymer cement mortar (PCM) is a widely used cementitious repairing material due to its considerable adhesive property with concrete. However, the polymers are sensitive to elevated temperatures. The behaviours of polymers and PCM at elevated temperatures (e.g., 60 °C) for short, moderate duration and cyclic conditions remain unknown and need to be explored. This work was aimed at studying the mechanical performance of PCM and PCM-concrete composites under the aforementioned exposure conditions.

In this study, two types of acrylic latexes, PA (polyacrylate) and PU/PA (polyurethane modified PA), are investigated in their influences on mechanical properties of mortar under different interaction mechanisms. In light of a previous study, the polymer–cement hydrates interaction mechanisms in PA and PU/PA modified mortars are illustrated respectively, and the microstructures are simulated using a computer model.

A laboratory study is performed to evaluate the influence of elevated temperature on the strength and microstructural properties of high strength concretes (HSCs) containing ground pumice (GP), and blend of ground pumice and metakaolin (MK) mixture. Twelve different mixtures of HSCs containing GP and MK were produced, water-to-binder ratio was kept constant as 0.20. Hardened concrete specimens were exposed to 250 C, 500 C and 750 C elevated temperatures increased with a heating rate of 5 C/min.

Impact resistance and strength performance of concrete mixtures with 0.36 and 0.46 water–cement ratios made with polypropylene and silica fume are examined. Polypropylene fiber with 12-mm length and four volume fractions of 0%, 0.2%, 0.3% and 0.5% are used. In pre-determined mixtures, silica fume is used as cement replacement material at 8% weight of cement. The results show that incorporating polypropylene fibers improves mechanical properties.
