Summary: This study investigates the effects of silica fume, nano-silica, and polypropylene fibers on the flexural properties of concrete. The results show that polypropylene fibers enhance the fracture energy and flexural strength of the specimens. The response surface method is used to establish the relationships between the parameters and the amounts of silica fume, nano-silica, and fibers, and the optimal mixture is determined to have 5% silica fume, 0.75% nano-silica, and 0.15% fibers. Scanning electron microscope (SEM) images confirm that silica fume and nano-silica improve the homogeneity and density of the samples.

Summary: This paper presents a study on the flexural strength of concrete beams reinforced with CFRP bars. The behavior of the CFRP bars and concrete, including compressive and tensile strain, reinforcement ratio, surface treatment, and compressive strength, were identified as factors affecting the flexural strength, deflections, and crack characteristics of the beams. The experimental results showed that current standards underestimate the ultimate flexural moment capacity of CFRP RC beams, while certain prediction models were more accurate. The paper also highlighted potential research topics for future studies.

Summary: Three modified solutions were used to treat the surface of basalt fibers (BF) in order to increase surface roughness and enhance bonding with concrete. The best mixture ratio solution was chosen after SEM and AFM tests. Modified basalt fibers (MBF) and nano-silica (NS) were used to improve the performance of recycled concrete (RC). Through flexural tests, the effects of replacement rate, MBF content, and NS content on the flexural properties of RC beams were determined.

Summary: The flexural behavior of high-strength and high-toughness (HSHT) reinforced concrete beams with negative Poisson's ratio and special spiral grooves on the surface was studied. Different parameters, such as the reinforcement ratio, compressive strength of concrete, loading mode, the number of HSHT steel bars in hybrid reinforcement, and longitudinal steel bars type, were investigated on their effects on failure modes, crack patterns, flexural stiffness, flexural strength, ductility, and energy absorption capacity. The results showed that the beams reinforced with HSHT steel bars exhibited superior crack width control ability and higher residual strength. The proposed flexural strength model accurately calculated the flexural strength of concrete beams reinforced with HSHT steel bars.

Summary: The study investigated the durability of glass fiber-reinforced polymer (GFRP) bars in alkaline environments. It was found that GFRP bars aged in an alkaline solution of pH 13.0 mainly experienced interfacial debonding between glass fibers and resin matrices, leading to a greater reduction in interlaminar shear strength. Equations were proposed to predict the long-term interlaminar shear strength of GFRP bars, showing rough consistency with measurement results.

Summary: There is no consensus among different design codes on how to predict punching shear for footings, and this inconsistency is inconsistent with experimentally observed capacity. The inconsistency is attributed to differences in the definition of the critical section, handling of influential parameters, modeling of subsoil, and consideration of reinforcement material characteristics. The current study evaluated the safety level of international design codes using 195 RC column footings and found that all selected methods underestimated the punching shear capacity compared to experimental results. The BS8110 design code was the most conservative, while PrEC2 was the closest to measurements and the most reliable.

A total of 12 columns with cross-sections of 150 x 150 mm and a height of 1200 mm, made of M120 grade UHPC and incorporating glass powder lime powder, were tested. The findings showed that the UHPC columns reinforced with BFRP had superior ultimate loads and behavior compared to concrete columns strengthened with steel reinforcement. The BFRP bar tensile strength was also significantly higher than that of reinforcing steel. The Ansys software-based analytical analysis accurately predicted the carrying capacity of UHPC columns.

Summary: This study analyzes the erosion mechanisms of NaCl solution on asphalt concrete and finds that NaCl solution softens asphalt and promotes the intrusion of crystalline salt into it. Salt crystallization alters the surface roughness of aggregates, resulting in a decrease in skid resistance but an improvement in compressive strength. Additionally, the concentration of NaCl solution initially has no significant impact on the mechanical performance of asphalt concrete, but its domination gradually increases with the intensification of cyclic effects.

Summary: This paper investigates the effect of freezing and thawing cycles on the tensile behavior of cracked ultra-high performance concrete (UHPC). The results show that long-term freezing and thawing action deteriorates the cracking strength, tensile strength, tensile strain, and strain energy of cracked UHPC. On the other hand, the action of water generally favors the development of tensile properties of UHPC. The crack distribution tends to be unsaturated under freezing and thawing environment, and the re-hydration reaction is hindered. The pore structure near the crack varies under different environments.
