Uniaxial tensile tests of basalt fiber/epoxy (BF/EP) composite material with four different fiber orientations were conducted under four different fiber volume fractions, and the variations of BF/EP composite material failure modes and tensile mechanical properties were analyzed. The results show that when the fiber volume fraction is constant, the tensile strength, elastic modulus, and ...

Aug 05, 2016· Modulus of elasticity (MOE) in concrete refers to the measurement of resistance a concrete structure has to deform or sway. That is, it measures the stiffness of the concrete. This measurement is used for high rise buildings, bridge piers, and other structural applications where the stiffness of the concrete is of essential importance.
Basalt rebar is a bar with continuous spiral ribbing formed by means of winding by basalt strip oiled in highly durable polymeric compound. Basalt rebar is a perspective composite material with a wide range of application in construction.
KODIAK FRP is the only US manufacturer of specification quality BASALT REBAR -Since 2013- Made in the USA. BFRP (Basalt fiber reinforces polymer) rebar is deformed rod used as high strength, non corrosive concrete reinforcement. Also sometimes referred to as Basalt rock rebar, Rock Rebar or BFRP rebar.
That is why applicable guidelines shall be followed during designing of FRP-reinforced concrete structures. The most crucial differences, like lower modulus of elasticity and shear strength, limited maximum sustained shear stress of FRP rebars, shall be also considered before designing.

The large ranges emphasize the need for testing at each site.
Flexural performance evaluation of NSM basalt FRP-strengthened ... The average tensile strength and modulus of elasticity of the BFRP bars were 1109.5 MPa, and 44.3 GPa, respectively, and the average strain at peak stress was 3.21%, as provided by the manufacturer.
where: E cm (t) is the secant modulus of elasticity of concrete at an age of t days E cm is the secant modulus of elasticity of concrete at 28 days f cm (t) is the mean concrete compressive strength at an age t days f cm is the mean compressive strength at 28 days according to Table 3.1.
The shear modulus is one of several quantities for measuring the stiffness of materials. All of them arise in the generalized Hooke's law: . Young's modulus E describes the material's strain response to uniaxial stress in the direction of this stress (like pulling on the ends of a wire or putting a weight on top of a column, with the wire getting longer and the column losing height),
High-modulus fibers in the composite (steel, asbestos, glass, basalt); Low-modulus composites fibers (nylon, polyethylene, polypropylene, etc.). Each of the composite have advantages and disadvantages, but most researchers prefer to use composites as a reinforcing material of basalt fibers.
The densities of basalt and concrete are similar, thus basalt spreads more evenly in fresh concrete and does not sink to the bottom or rise to the top while hardening. Basalt has good mechanical properties – a high elastic modulus and strength. Tests have shown that basalt fibre, independent of the dosage, does not affect concretes'
Basalt is considered an igneous rock with fine grains due to the rapid cooling of lava. ... Modulus of elasticity of concretes produced with basaltic aggregate ... of basaltic aggregate on the ...
FRP Rebar in Slabs on Grade Benefit from Low Modulus of Elasticity Steven E. Williams, PE Williams & Works, Inc., 549 Ottawa Ave. NW, Grand Rapids, Michigan 49503 April 10, 2015 Abstract: Steel reinforcement of concrete has been used for many years. Its primary shortcoming is that it is easily corroded, and corrosion results in structural failure.
Modulus of Elasticity of Rock Modulus of elasticity of rocks depend upon several factors, such as, Type of rock Porosity Grain size Water content Value of modulus of elasticity can be determined by static or dynamic methods. Higher value of modulus of elasticity indicates good quality rock having sound composition. Typical values of modulus of [.]
changes in their elastic properties. • However, the effect of stress-cycling on mechanical and elastic properties of volcanic rock remains largely unknown. Modelling of Mt. Etna has previously assumed values of Young's modulus ranging from 50-100 GPa and a Poisson's ratio of 0.25 [Cayol and Cornet, 1998; Bonaccorso and Davis, 1999].
