Oct 01, 2018#0183;#32;The impactresistance behaviour of basaltpolypropylene fibrereinforced concrete containing the mineral admixture (BPFRC) was experimentally investigated under impact loading using a 75 mm splitHopkinson pressure bar. The results showed that the dynamic compressive strength, dynamic elastic modulus and critical strain of BPFRC increased with increasing strain rate.
Jul 15, 2009#0183;#32;Abstract. Industrial wastes, slag and fly ash, were used to produce geopolymeric concrete (GC), and which was reinforced with short basalt fiber. Impact mechanical properties of basalt fiber reinforced geopolymeric concrete (BFRGC) of three different matrix strengths were investigated using a 100mmdiameter split Hopkinson pressure bar (SHPB), and strain rate effects on dynamic

Characterization of Basalt FiberReinforced Polymer (BFRP) Reinforcing Bars for Concrete Structures Due to noncorrodible nature, fiberreinforced polymers (FRP) materials are being used as main reinforcement in reinforced and prestressed concrete structures subjected to
new type of composite reinforced material and it has obtained broad attention in rehabilitation of concrete structures. Basalt fibres are made from basalt rocks by way of melting process. It is known that the basalt fibres have higher ultimate tensile strength than glass fibres. Several experimental investigations on mechanical properties
This study aims to adopt the acoustic emission (AE) technique to evaluate the reinforcing effect of basalt and steel fibers on the fracture resistance of asphalt concrete (AC) under indirect tension (IDT) testing at low temperature. Control asphalt concrete (CAC) with no fibers was also tested for comparison. The AE counts and durations were recorded and analyzed to characterize the fracture processes of basalt
May 01, 2020#0183;#32;Basalt fibre (BF) has a high elastic modulus, whereas polypropylene fibre (PF) with a low elastic modulus has good ductility. The proper amounts of hybrid BF and PF can perform a particular function at different scales of concrete that remarkably improve the macroproperties [ [46], [47], [48] ].
Jun 30, 2018#0183;#32;Basalt textile reinforced concrete (BTRC) specimens were tested at different impact velocities of m/s, m/s and m/s and temperatures of 25, 0, 25, 50 and 100 #176;C to study possible influences on their impact resistance and failure patterns.

Basalt bars for concrete reinforcement called Basalt Fiber Reinforced Plastic (BFRP) is a new material, so it is necessary to identify the differences and limitations of their use in the concrete structures in relation to traditional steel reinforcement of concrete structures.
Jan 20, 2018#0183;#32;As a new type of environmentally friendly material, basalt fiber is made from basalt via the wire drawing technique between 1450 #176;C and 1500 #176;C, and it mainly consists of SiO 2, Al 2 O 3, CaO, K 2 O, MgO and TiO 2. Its operating temperature and tensile strength range from 269 to 960 #176;C and from 4000 to 4850 MPa, respectively.
As fabric reinforcements show repeating ondulations of warp and fill yarn, simple mixtures laws reach their limits. That is the reason why the mesoscopic dimension, lying between the microscopic and the macroscopic dimension, has to be taken into account when a mechanical characterization of fabric reinforced composites is carried out.
Sep 20, 2020#0183;#32;1. Introduction. It is estimated that about 10 billion tons of concrete are produced annually worldwide consuming huge amounts of raw materials, .Coarse aggregates (CA) make up the majority of the concretes constituents with about 55% to 75% by volume .The worldwide annual CA demand had reached up to billion tons in 2015 .Such high demands initiated a rapid depletion of natural source
Jan 01, 2018#0183;#32;Abstract. Basalt fibers were surface treated with silane coupling agents as a method to enhance the adhesion and durability of fibermatrix interfaces in concrete based composite materials. In particular, this work has been focused on the study of basalt fibers chemical coatings with aminosilanes and their subsequent characterization.
