Structural Design Calculation of Basalt Fiber Polymer-Modified RPC Beams Subjected to Four-Point Bending

Abstract: In this paper, a basalt fiber surface was treated with coupling agent KH-550 and hydrochloric acid, and the basalt fiber polymer-modified active powder concrete (RPC) material was prepared. There are significant differences in material composition and properties between basalt fiber polymer-modified RPC and ordinary concrete, and the structural design calculation (cracking moment and normal section bending bearing capacity) of an ordinary reinforced concrete beam is no longer applicable. Thus, mechanical param… Show more

“…Finally, from a price point of view, the cost of our elements is reduced and is more economical, as confirmed by our economic analysis. This is in good agreement with the results of the authors [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]35,[37][38][39][40][41][42][43][44][45][46][47][48][49][50].…”

“…Finally, the works of the authors involved in the study of polymer composite concrete bending elements (beams) [2,5,8,[11][12][13]15,16,35,[37][38][39][40][41][42][43][44][45][46][47][48][49][50] were of particular interest for the development of this study. To improve the performance of bending elements, researchers studied the following for their reinforcement: fiber-reinforced polymers (FRP), glassreinforced polymers (GFRP), composite polymers, reinforcement with jute-polyester fiber (JPFRP), polymers, reinforcement with basalt fiber (BFRP), carbon (CFRP) and aramid (AFRP) fibers.…”

“…Kassym Yelemessov researched the prospects of the application of building structures made of polymer concrete composites on the basis of strength analysis [7]. Basalt fiber polymer-modified reactive powder concrete (RPC) materials were prepared by Yafeng Gong [8]. However, prevailing formulations of low-calcium fly ash-derived geopolymers confront issues, such as uncontrolled solidification times, hindering streamlined construction practices.…”
