Jul 07, 2019· This article presents the results of a research program investigating the use of newly developed sandcoated basaltFRP (BFRP) bars and ties in axial–flexural members made with highstrength concrete (HSC). Eight fullscale concrete columns 400 × 400 mm in cross section and 2,000 mm in height were constructed and tested.
The aim of this paper is to estimate the uniaxial compressive strength (UCS) of rocks with different characteristics by using genetic expression programming (GEP). For this purpose, five different types of rocks including basalt and ignimbrite (black, yellow, gray, brown) were prepared.
Laboratory tests were conducted on rock cores collected from over 22 locations within the Mumbai city limits. The samples were tested in accordance with specifications. Correlations between the uniaxial compressive strength (UCS) and the point load strength index (I ) were developed.
Compressive Strength Testing of Plastics. The compressive strength of a material is the force per unit area that it can withstand in compression. This is in contrast to the more commonly measured tensile D695 is the standard test method in the USA.

axialcompressive strength and drilling rate for basalts from DSDP Hole 504B. Given the small supply of starting material, the availability of apparatus for unscheduled testing, and but little free time, we have roughly measured certain mechanical properties—static Young''s modulus, ultimate compressive strength, and relative duc
Basalt fiber is cheap and has excellent mechanical performance. In addition, in combination with the environmentally friendly coconut fiber, it can contribute to sustainable construction materials. In this study, a composite material consists of basalt fiberreinforced polymer (BFRP) tubeencased coconut fiberreinforced concrete (CFRC) is developed.
In order to investigate the influence of basalt fibers (BFs) on the mechanical performance of recycled aggregate concrete (RAC), some groups of RAC specimens were first tested involving different types of fibers such as carbon fibers, steel fibers, polypropylene fibers and hybrid fibers. The main four indices for the investigation consisted of cube compressive strengths, axial compressive ...
The unconfined compressive strength (UCS) is the maximum axial compressive stress that a cylindrical sample of material can withstand under unconfined conditions—the confining stress is zero. It is one of the key parameters needed to understand rock instability behavior during drilling, sanding issues, and other rock mechanical studies.
Axial compressive strength testing of single carbon fibres 29 four have serious drawbacks because of their indirect interpretations of compressive properties. In methods such as the elastica loop and bending beam tests, the state of stress developed in the fibre is not purely axial compression (for example, see [15, 21]).

For this, the compressive strength of each brick tested was converted to the normalized compressive strength and the average value of the normalized compressive strengths was calculated as MPa. Substituting these numerical values into Eq. (1), the mean compressive strength of the unconfined masonry was computed as MPa.
According to the axial compressive experiment of concrete cylindrical and quadrate specimens confined by Basalt fibers, the stressstrain curves, bearing capacity and peak strain were obtained. 12 quadrate and 12 cylindrical column specimens were prepared and wrapped with 2 to 4 layers of BFRP fibers. The results show that: (1) comparing with unconfined specimens, the compressive strength and ...
the Uniaxial Compressive Strength and Deformability of Rock Materials PART 1. SUGGESTED METHOD FOR DETERMINATION OF THE UNIAXIAL COMPRESSIVE STRENGTH OF ROCK MATERIALS 1. SCOPE This method of test is intended to measure the uni axial compressive strength of a rock sample in the form of specimens of regular geometry.
Basalt fiber was added to the traditional cementbased materials to improve the physical and mechanical properties. The mixture ratio of the matrix, the basalt fiber content, and the superplasticizer type as well as its contents were designed optimally. The fluidity test, axial compressive strength and cube compressive strength test, flexure strength test were carried out.
Then, the cylinders were wrapped with BFRP sheets and retested under axial compression. The experimental results showed that compared with the plain concrete, the ultimate compression strength and axial strain capacities of the predamaged concrete were improved by 10–104% and 186–590% respectively after the BFRP confinement.
application. Adding basalt fiber into concrete is an important method to improve the stress performance of short RC columns. Effects of basalt fiber on the axial compressive mechanical properties of short RC columns with spiral stirrups were explored in this study.
