Summary: Basalt fiber (BF) has gained significant attention in recent years for its advantageous mechanical properties and cost-effectiveness in basalt fiber reinforced concrete (BFRC). This study investigates the performance of BFRC after cryogenic freeze-thaw cycles, examining the effects of fiber volume fraction, temperature gradient, and freeze-thaw cycles on various strengths and analyzing the damage mechanism through scanning electron microscopy (SEM). The results reveal that BFRC reaches peak compressive strength at a fiber fraction of 0.1% during freezing and thawing cycles from room temperature to -80 degrees C. The addition of basalt fibers reduces microstructural damage and improves plastic degradation characteristics. Furthermore, the optimal fiber content for compressive strength increases with decreasing minimum temperature of the cryogenic freeze-thaw cycle while splitting tensile strength and flexural strength improve with increasing fiber content in the cryogenic freeze-thaw environment.

Summary: This research experimentally investigated the mechanical properties of concrete with waste steel scrap, showing that the addition of waste steel scrap can improve compressive strength and splitting tensile strength. The modulus of elasticity and peak strain of the concrete also increased with an increase in waste steel scrap volume. However, the workability of concrete decreased with a higher amount of waste scrap added.

Summary: Environment-friendly concrete is gaining popularity due to its low energy consumption and minimal environmental damage. However, the increasing population and demand for construction result in a decrease in natural resources and an increase in construction waste. Therefore, the use of recycled materials and recycled coarse aggregate in concrete is crucial for addressing environmental issues.

Summary: Substantial volumes of concrete waste generated from construction and demolition activities have become a global concern from an environmental standpoint. Utilizing recycled crushed stone aggregate (RA) as a replacement for natural crushed stone aggregate (NA) in concrete mixtures can help address this issue. The present study explores the effect of different fibers, such as galvanized iron (GI) fiber and polypropylene (PP) fiber, on the physical and mechanical properties of both natural aggregate concrete (NAC) and recycled aggregate concrete (RAC). The findings demonstrate that incorporating GI fiber leads to a more significant improvement in compressive strength compared to PP fiber. Concrete reinforced with 15 mm long GI fiber exhibits the highest compressive and split tensile strengths. GI fiber also has a better ability to prevent crack formation in concrete compared to PP fiber. Additionally, incorporating GI fiber enhances the flexural strength and toughness of the concrete. Cost sensitivity analysis reveals that replacing natural stone with recycled stone in GI fiber reinforced concrete can potentially save approximately 18.8% of energy costs. The study recommends the use of 15 mm long GI fiber with an aspect ratio of 30 in both NAC and RAC.

Summary: The addition of PVA fiber reinforcement has a significant impact on the mechanical behavior of cemented silty soil, leading to increased compressive strength, improved tensile strength, and enhanced flexural strength. Furthermore, the inclusion of fibers effectively alters the brittle failure pattern, improves toughness, and ductility. Additionally, a regression model was proposed for predicting the strength properties.

Summary: This experimental study investigates the mechanical characteristics of CFRP bars, including their tensile, compressive, and shear strength, as well as modulus of elasticity. Understanding these properties is crucial for analyzing the behavior of concrete structures reinforced with CFRP rebars. The use of a coefficient allows for the prediction of tensile strength based on shear strength. The results confirm that CFRP's tensile strength is influenced by its diameter due to the shear lag effect.
