DEVELOPMENT OF RAPID-HARDENING HIGH-STRENGTH FIBER-REINFORCED CONCRETE WITH INCREASED IMPACT RESISTANCE

The article describes the development of rapid-hardening, high-strength fiber-reinforced concrete with increased impact resistance for protective structures. Fiber-reinforced concretes with the addition of Portland cement CEM II/A-LL 42.5 R (C = 390 kg/m3) with polymer structural fiber PMS 1/60 with the addition of PCE were studied. The addition of PMS 1/60 fiber to concrete increases impact strength by 2.8-3.7 times and achieves a strength class of C 40/50. Fiber-reinforced concretes with the addition of Portland cement CEM II/A-S 52.5 R were studied.

RESEARCH ON THE MECHANICS OF BIONIC PROSTHETIC FINGERS: OBJECTIVITY IN THE IMPROVEMENT OF MECHANICAL COMPONENTS

This paper examines important challenges in the mechanics of bionic prostheses, focusing on improving their functionality, reliability, and accessibility against increasing global amputation rates. This research aims to identify key mechanical components requiring development and to substantiate the advantages of implementing compliant mechanism technology in bionic finger designs.
