To rapidly repair the damaged buckling-restrained brace serving as energy absorption member during earthquake, assembled method of wrapping component with FRP cloth is proposed. In this research, a series cyclic tests on six (ABRB) wrapped three kinds FRPs (carbon fiber, glass fiber and basalt fiber) were performed. The tested results show that all specimens excellent hysteretic performance sim...

This paper presents an experimental study on the tensile behavior of basalt-fiber-grid-reinforced mortar (BGRM) before and after exposure to elevated temperature 300 °C considering effect fiber grid type, short polyvinyl alcohol (PVA), high-temperature time. The results show that plates reinforced with woven textile T25 fiber-reinforced polymer (FRP) G50 exhibited more pronounced strain-hardeni...

Basalt outcrops are significant features in the Western United States and consistently present challenges to Natural Resources Conservation Service (NRCS) soil mapping efforts. Current soil survey methods to estimate basalt outcrops involve field transects and are impractical for mapping regionally extensive areas. The purpose of this research was to investigate remote sensing methods to effect...

Fiber-reinforced polymer (FRP) is the most promising technique in present era to bring sustainability, reliability, and pseudo ductility concrete structures due its superior properties. Thermoplastic thermoset polymers are thrown-out synthetic waste that contributes environmental pollution for a long time. Knowing this issue an attempt was made use High-Density Polyethylene Fiber (HDPE) fillers...

Introduction: Lunar mare basalts are products of partial melting of the lunar interior, thus are keys to understand the chemical compositions of the source mantle. However, the iron-enrichment of the mare basalt samples returned by Apollo and Luna missions, compared to the terrestrial basalts, have led to an inference that the mare basalt hand specimen do not represent the primary magma composi...

[1] Moon Mineralogy Mapper (M) image and spectral reflectance data are combined to analyze mare basalt units in and adjacent to the Orientale multiring impact basin. Models are assessed for the relationships between basin formation and mare basalt emplacement. Mare basalt emplacement on the western nearside limb began prior to the Orientale event as evidenced by the presence of cryptomaria. The...

Due to the significant temperature difference and high solar radiation in high-altitude areas, asphalt pavement has been freeze-thaw cycles service conditions for a long time, resulting shorter life. To extend life of this study uses basalt fiber toughen mixture, characteristics under coupled effects aging were evaluated. First, cycles, content selected as independent variables conduct Box–Behn...

Fiber-reinforced polymers (FRPs) have been widely utilized to improve the seismic performance of deficient reinforced concrete (RC) columns. In recent years, one of the emerging types of FRPs used is basalt fibers. In this study, the performance of existing columns was experimentally examined before and after applying near-surface mounted (NSM) basalt FRP (BFRP) rebars as a retrofitting techniq...

Basalt continuous fibers are regarded as an inert and naturally occurring material that is produced from basalt rock by using single component raw material and drawing and winding fibers from the melt. Basalt based materials are environmentally friendly and nonhazardous. Basalt FRP (BFRP) composites as a reinforcement not only display a higher strength and modulus, but also a similar cost, and ...

Imnaha Basalt and Grande Ronde Basalt (RI) of the Columbia River Basalt Group form a small synclinal basin immediately west of Riggins, Idaho. The displacement of the margins of the basalt outcrop, of the synclinal axis, and of a dike of Saddle Mountains(?) Basalt define a pattern best explained by a model of west-northwest to eastsoutheast and north-northwest to south-southeast dextral strike-...
