In order to prepare basalt fibers-reinforced cement-based mortars with higher compatibility between reinforcement and matrix, fibers new surface treatments (sizing) were studied looking for enhanced interaction at the interphase cement matrix. As-received, calcinated, activated silanized (by three silane aqueous solutions: i) ?-aminopropyltriethoxysilane, APTES; ii) ?-aminopropylmethyldiethoxys...

The development of perspective concrete mixes capable resisting the action external loads is an important scientific problem in modern construction industry. This article presents a study influence steel, basalt, and polypropylene fiber materials on concrete’s strength deformation characteristics. A combination various types dispersed reinforcement considered, by methods mathematical planning e...

The paper presents two experimental methods for basalt processing by microwaves, and their results. One method employs a single-mode cavity to melt basalt, and to produce a volcanic glass (obsidian). The other method uses an open-end applicator (i.e. a microwave drill [1]) to form holes in basalt rocks. Experimental observations of the basalt interactions with microwaves in these two schemes ar...

Abstract This paper firstly presents an experimental investigation of the effects heat treatment temperatures and atmosphere on tensile strength structure basalt fibers. The results show that fibers after in air (200–600 °C) have characteristics amorphous state due to oxidation Fe 2+ into 3+ . On contrary, vacuum induces crystallization reason is cations can act as network modifiers participate...

An experimental program consisting in producing and testing reinforced concrete pipes (RCPs) under the three-edge bearing tests considering different types of reinforcement was carried out. Four RCPs were produced, these with: (1) polypropylene macrofibers; (2) basalt microfibers; (3) combination both (hybrid reinforcement); (4) plain concrete. The analysis crack patterns service ultimate mecha...

The addition of short steel wire, polypropylene, basalt and other fibers can improve the durability index concrete, such as compression resistance, cracking resistance carbonization which has been widely recognized in industry. For fiber most current researches are qualitative, quantitative value various needs to be further investigated. In view this, linear fitting polynomial were introduced i...
