The basalt rebar has unique technical characteristics that ensure its positive effect on the concrete structures where it is used. So, the basalt rebar: 3 times stronger than steel rebar (the strength of basalt rebar is MPa, depending on the diameter, whereas steel rebar .
Chemical Composition and Mechanical Properties of Basalt and Glass Fibers: A Comparison. The SiO2 and Al2 O3 content of basalt fibers showed correlation with tensile properties of fibers. Results revealed that continuous basalt fibers were competitive with glass fibers and short basalt fibers were weaker in terms of quality and mechanical properties.

Metamorphic rock composed mainly of dolomite crystals. The crystalline texture is the result of metamorphosis of limestone/dolostone by heat and pressure plus / minus the influence of aqueous solutions. Marbles are variable in grain size and colour (due to impurities), are often massive, but can also show banding and foliation.
Basalt fiber reinforced concrete. Along with the widespread use of reinforced concrete special attention, in our opinion, deserve composite materials, in which the role of the matrix performs the cement stone produced based on Portland cement, as well as valves, various .
Acid Resistance, Water Permeability and Chloride Penetrability of Concrete Containing Crushed Basalt as Aggregates 294 Volcanic rocks are widespread in AsSwaida'a region of Syria . AsSwaida'a is basically an agricultural city. It is a mountainous region covered with about 3 and 5 million trees of apple and grapevine respectively.
Jun 01, 2004· Most promising for composites are basalt fibers, which were presented at the JEC show by two Russian companies—Kamenny Vek and Sudaglass Fiber Technology Inc. ( office in Houston)—as well as a Belgian firm named Basaltex. Basalt is cooled lava, a .
Basalt is Earth's most abundant bedrock, and a very important rock. The Earth's ocean basins are underlain by basalt, but it is less common on continents. However, lava flows and flood basalts underlie several percent of Earth's land surface. It is an igneous rock and is usually finegrained and darkcolored, composed mainly of plagioclase and pyroxene minerals.
Basalt and other mafic rocks 34 Felsic igneous rocks 35 ... 7. Thermal conductivity of dolomite, air in pores 19 8. Thermal conductivity of dolomite, water in pores 19 ... All the important thermal properties of rocks can be estimated from the graphs and tables in this report.
The geometrical and mechanical properties and chemical composition of different basalt and glass fibers have been investigated. Tensile tests were performed on short basalt fiber made by melt blowing, glass fiber and three different types of continuous basalt fibers made by spinneret method.
The structure of concrete when using basalt fibers is close to the structure of reinforcement with steel mesh, but basaltconcrete has a higher reinforcement strength, due to higher degree of dispersion of basalt fiber in the reinforced stone, but the very fiber has a higher strength than the steel mesh.
compared with the geopolymer concrete without basalt fibers. Fibers are added to the geopolymer concrete in the range of % to % at % increments. Keywords: Basalt fiber, compressive strength, split tensile strength, Flexural strength I. Introduction Concrete is the most used construction material around the world.

Use of basalt in asphalt concrete mixes. Results showed that the optimal mix was the mix that had basalt coarse aggregate and limestone fine aggregate. In order to overcome the stripping potential of the optimal mix, 20% of the filler portion of the aggregate, material .
Basalt Fiber Tech Chopped Strands was successfully used while constructing one of car tunnels in Luxemburg. Basalt Fiber Tech Chopped Strands gives an opportunity to get crack and hit resistant tunnel primary surface with the less thick layer than it would be while using ordinary concrete.
Basalt fiber is a material made from extremely fine fibers of basalt, which is composed of the minerals plagioclase, pyroxene, and olivine. It is similar to fiberglass, having better physicomechanical properties than fiberglass, but being significantly cheaper than carbon fiber. It is used as a fireproof textile in the aerospace and automotive industries and can also be used as a composite to produce products such .
