Prediction of elastic mechanical properties such as uniaxial compressive strength (UCS) and static Young's modulus (E s) is one of the main purposes of studies in geological, geotechnical, geophysical, petroleum, and rock engineering projects. The UCS test is applied to determine them. However, this test is destructive, expensive, time-consuming, and requires …
Basalt fiber (BF) is an excellent reinforcement material thanks to its high mechanical strength, ecological compatibility, low cost, and excellent chemical resistance [1].The introduction of BF into various matrices can effectively enhance the mechanical properties and durability of the latter [2].For example, basalt fiber reinforced concrete (BFRC) has emerged …

This manuscript proposes a strength and ductility of reinforced concrete (RC) using basalt fibre-reinforced polymers (BFRP). The lightweight materials like fibre-reinforced polymers (FRPs) are providing superior structural performance and durability in reinforced concrete members over traditional materials. Due to its light weight property, they are proposed for building repair and ...

Many studies have shown that artificial neural networks (ANNs) are useful for predicting the unconfined compressive strength (UCS) of rocks. However, ANNs do have some deficiencies: they can get trapped in local minima and they have a slow learning rate. It is widely accepted that optimization algorithms such as particle swarm optimization (PSO) can improve …
The strength of the block will contribute to the strength of the units used in a structure. For example, walls built with poor quality blocks that falls short of the standard strength are likely to fail, thereby causing severe damage to the structure and sometimes even lost of lives and properties. This shows that there is need to know the ...
The aim of this study is to understand the strength behaviour and fragment size of rocks during indirect, quasi-static and dynamic tensile tests.
