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 …

Basalt is a kind of volcanic rock that originates from mafic lava flows. It is widely distributed on the earth and has been used for the construction of roads, bridges, and buildings. The melt of basalt can be further used to produce high-performance fiber, wool, and cast stone [[1], [2], [3]]. Therefore, there is a great demand and market for ...

Compared with the compressive strength 250 MPa of basalt at 25℃, the compressive strength σ c after heat treatment at 200 ℃ and 400 ℃ increases by 10.50% and 15.85%, respectively. The main reason is that the expansion of mineral particles causes the gradual closure of primary fractures, which increases the compactness of …

Basalt, sometimes known as white, green, or blue basalt, is igneous rock. This stone is good and bad for construction because it is strong and rough. This roughness makes it difficult to use the granite for any purpose. It has a specific gravity of about 3 and compressive strength of 200 to 350 N/mm2 (2039 to 3569 kg/cm2).

Basalt is a type of volcanic rock that is formed from the solidification of molten lava. It is an igneous rock, meaning it is formed through the cooling and solidification of magma or lava. Basalt is one of the most common rock types on Earth, and it can be found in various locations around the world, both on land and under the ocean floor.
