The article touches upon the technology of basalt fiber manufacturing and prospects of its use in dental practice. Two kinds of construction using basalt fiber have been proposed. The first one is a splinting construction for mobile teeth and the second one is the reinforced base for removable plate-denture. The work presents the results of the investigation of physical and mechanical propertie...

Incorporating fibers into asphalt mixtures as additives and stabilizers can significantly enhance the performance of pavements. This study aimed to analyze impact using basalt bamboo modifiers on properties mastics. The effects different types rutting resistance, fatigue elastic recovery, low-temperature cracking were tested frequency scanning, linear amplitude scanning (LAS), multiple stress c...

Abstract Many civil engineering structures are constructed in terms of aspect like economy, strength and serviceability requirement. The fibres play a prominent role bridging the micro cracks at early stage crack propagation makes structure ductile. impact chopped basalt fibre on high-strength reinforced concrete composites is focus this research. hardened property was investigated compared it ...

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...

The construction of coastal ports requires the use materials that meet demands marine environment, to prevent underwater concrete structures from cracking and spalling easily; basalt fiber is used delay expansion formation cracks. This research studies behavior for prefabricated piles with Portland Cement Type I fibers added in 0.1%, 0.3% 0.6%; results indicate suitable concrete, slump decrease...

This paper discusses the influence of fiber reinforcement on properties geopolymer concrete composites, based fly ash, ground granulated blast furnace slag and metakaolin. Traditional composites are brittle in nature due to low tensile strength. The inclusion fibrous material alters behavior along with a significant improvement mechanical i.e., toughness, strain flexural Ordinary Portland cemen...
