Test results indicated that hybrid fibers can effectively improve the compressive strength of concrete; that the maximum increases in compressive strength of C30, C40, and C50 concrete were %, %, and %, respectively; and that the effect of basalt fiber on compressive strength was greater than that of polypropylene fiber.
Basalt fiber is a material made from extremely fine fibers of basalt, which is composed of the minerals plagioclase, pyroxene, and is similar to fiberglass, having better physicomechanical properties than fiberglass, but being significantly cheaper than carbon is used as a fireproof textile in the aerospace and automotive industries and can also be used as a composite to ...

• Compressive strength : ~144 292 MPa (20,885 –42,351 psi) Basalt rock can be 47 X stronger in compression than normal Portland cement concrete typically used on Earth. How can basalt rock be formed to be comparable to concrete as a construction material? Sintered basalt regolith has achieved 206 Mpa (30,000 psi) in compression tests
When the concrete contains basalt fiber, the compression strength of it is unstable, the tensile strength increases with fiber content, and durability and impact resistance increase considerably . Also basalt fiber has little effect on compressive strength of the fiber reinforced concrete but significantly increases its toughness . The ...

Concrete is one of the most important building materials of engineering structures and especially construction applications. Since compressive strength is the most effective parameter for ...
the compressive strength of highstrength concrete (Giaccio, Rocco, Violini, Zappitelli, and Zerbino 1992), almost all of the coarse aggregate was fractured in the limestone specimens, while loadinduced cracks occurred mostly at the matrix
Uniaxial Compressive Strength of Composite Rock Material The uniaxial compressive strength of intact rock specimen of homogenous and isotropic rocks such as granite, sandstone, basalt and etc had been well ...
As shown in Fig. 7, the dynamic compressive strength of all groups of concrete increases with increasing strain rate. At the strain rate range in this study, the dynamic compressive strength of,, and is greater than that of NC. At the low strain rate, the dynamic compressive strength of is lower than that of NC.

This paper presents an experimental study on the compressive behavior of circular concrete columns confined by a new class of composite materials originated from basalt rock, Basalt Fiber Reinforced Polymer (BFRP). The primary objective of this study is to observe the compressive behavior of BFRPconfined cylindrical concrete column specimens under the .
Sep 09, 2019· The test results show that both the unconfined compressive strength (UCS) and splitting tensile strength (STS) at a given basalt fiber content increase significantly with increasing calcite content, whereas the axial strain of the peak failure state decreases with increasing calcite content.
6. Using basalt fibers slightly increased the 28day compressive 0 strength (f c ) of concrete containing fly ash and admixtures with a low watercement ratio. In addition, the early compressive strength of concrete containing fly ash and admixtures may significantly increase due to the use of basalt fibers. 7.
In order to study the mechanism and effect of basalt fiber reinforced clay soil, a series of unconfined compressive strength tests conducted on clay soil reinforced with basalt fiber have been performed under the condition of optimum water content and maximum dry density. Both the content and length of basalt fiber are considered in this paper.
MPa as shown in The increase in compressive strength is about % for an addition of % basalt fibres. For 1%, % and 2% of basalt fibres, there is an increase in compressive strength of 14%, 27% and 38% respectively. From the test results, it can be seen that as the percentage of fibre increases, the compressive strength also ...
