ABSTRACT. ABSTRACT: Understanding and predicting the intact strength of rock is very important in design of foundations, tunnels, and in other engineering projects. The presence of vesicles within basalt has a direct impact on the unconfined compressive strength (UCS) of the intact rock. Over 130 basalt samples from foundation projects for …
Fibres are used in concrete to improve its structural integrity. Nowadays, among all basalt fibres, an inert mineral fibre is gaining more importance due to its exceptional properties, which include resistance to corrosion and low thermal conductivity. It also improves tensile strength, flexural strength and toughness of concrete. It can be …

Basalt is among the most used rocks as aggregate, ballast, ornamental stone and for other construction purposes. Therefore, the uniaxial compressive strength (UCS) and elasticity modulus (Ei) of intact rock are required to be known for several purposes. For this reason, the purpose of the present study is to develop various non …

From the analysis results, it can be found that the effect of basalt fiber on the compressive strength of RPC is limited, and the high content of basalt fiber even reduces the strength of RPC obviously. This is because the basalt fiber mainly improves the tensile stress and crack resistance of concrete, solves the fragile tensile response of ...

The effect of basalt fiber (BF) on HPC was investigated in many previous types of research [4,5,6,7,8,9,10,11]. In fact, BF was added to HPC to increase the durability, tensile, and flexural strengths [12,13,14]. For example, Kharun et al. added basalt fiber to High-Strength Concrete (HSC) to enhance tensile and flexural strength. …
