Modifying the Sand Concrete with Recycled Tyre Polymer Fiber to Increase the Crack Resistance of Building Structures
Recycled tyre polymer fiber derived from waste tires has gained attention as a promising additive for concrete reinforcement, particularly for building materials that require resistance against cracking. The study shows that the addition of treated fiber in small amounts increases the flexural strength of concrete, while the addition of untreated fiber decreases the compressive and flexural strengths. +Overall, using recycled tyre polymer fiber as a low-cost alternative to other fibers can produce durable building materials.

Understanding the Moisture Sensitivity of Warm-mix asphalt Binders Based on Bond Strength
Moisture damage in asphalt mixtures is a result of losing bond strength at the interface of the asphalt binder and aggregate matrix. Selecting materials that resist moisture damage is crucial for warm-mix asphalt (WMA) mixtures. The study found that WMA binders imparted similar or even higher bond strength than the base asphalt binder, with the chemical-based WMA additive Rediset showing the best performance.

A State-of-the-Art Review on Axial Compressive Behavior of Concrete-Filled Steel Tubes Incorporating Steel Fiber and GFRP Jacketing
This article reviews the use of fibers to improve the structural response of reinforced concrete-filled steel tubes (CFSTs). Steel fibers significantly enhance load-carrying capacity and ductility, while adding SFs by 1% is more effective than 1.5%. GFRP sheets and jackets increase compressive strength, load-carrying capacity, stiffness, and energy absorption capacity. Publish by: MPDI Publish on: 9 March 2023 Read Article

Dynamic Response of Reinforced Recycled Aggregate Concrete Pavement under Impact Loading
Dynamic Response of Reinforced Recycled Aggregate Concrete Pavement under Impact Loading Author(s): Jifeng Yuan, Jin Wu, Tian Su, 5ORCID andDadi Episode Info: Chinese researchers compared four reinforced recycled aggregate concrete pavements with varying thickness and ratios of reinforcement and one reinforced normal concrete pavement to determine its potential use for airport runway pavement. Researchers concluded the dynamic performance of reinforced recycled aggregate concrete pavement was worse than reinforced normal concrete due to lower elastic modulus and weaker interfacial transition zone, though performance improved with increasing thickness and reinforcement ratio.
