This study investigates the mechanical properties of natural fiber-reinforced concrete (FRC) through addition fibers such as kenaf (KFRC), jute (JFRC), and coconut (CFRC). The evaluation focused on key including compressive strength, split tensile flexural strength. Fiber combinations were introduced in a fiber volume fraction 0.5%, with lengths standardized at 20 mm. A water-to-binder ratio 0.44 was maintained for all mixes. Six specimens tested each parameter after curing period 28 days. objective this research to assess potential like kenaf, jute, developing sustainable FRC while maintaining or improving its properties. Results demonstrated that inclusion specified length concentration positively influenced post-cracking performance splitting Among combinations, reinforced (JFRC) exhibited superior compared other combinations.

Abstract This Assessment Update by the Environmental Effects Panel (EEAP) of United Nations Environment Programme (UNEP) addresses interacting effects changes in stratospheric ozone, solar ultraviolet (UV) radiation, and climate on environment human health. These include new modelling studies that confirm benefits Montreal Protocol protecting ozone layer its role maintaining a stable climate, both at low high latitudes. We also provide an update projected levels UV-radiation during twenty-first century. Potential environmental consequences intervention scenarios are briefly discussed, illustrating large uncertainties of, for example, Stratospheric Aerosol Injection (SAI). Modelling predict that, although SAI would cool Earth’s surface, other factors be affected, including depletion precipitation patterns. The contribution to global warming replacements ozone-depleting substances (ODS) assessed. With respect breakdown products chemicals under purview Protocol, risks ecosystem health from formation trifluoroacetic acid (TFA) as degradation product ODS currently de minimis . change continue have complex interactive due largely activities.

In the pursuit of sustainable construction practices, utilization recycled concrete has emerged as a pivotal strategy, distinguished by its commitment to resource conservation and environmental stewardship. Nevertheless, inherent micro-porosity micro-cracking within old mortar may lead weak bonding performance at interfacial transition zone, culminating in diminished strength, reduced density, elevated water absorption rates compared conventional concrete, which critically impairs cold climates subjected freeze-thaw cycles. Consequently, this paper provides structured examination frost resistance properties cycling. Initially, study delineates mechanisms frost-induced damage synthesizing degradation pathways observed both during exposure. Subsequently, detailed analysis is conducted identify factors affecting resistance, encompassing proportion moisture affinity aggregates, addition silica fume fly ash, water-to-cement ratio, degree saturation. final segment, compiles reviews strategies for bolstering including incorporation air-entraining admixtures, fiber reinforcement, aggregate modification approaches. The objective research offer thorough comprehension with concentration on damage, critical determinants interventions augment resilience against freezing conditions. On basis, present paper, conjunction characteristics current status proposes recommendations application regions. This review anticipated facilitate researchers gaining comprehensive understanding measures enhance resistance. Furthermore, it aims assist engineering technical personnel selecting appropriate treatment methods improve regions, thereby promoting practical such areas.
