Stress-strain relationships and modulus of elasticity of rocks
It should be noted that no explicit correlation between the strength of rocks and the properties of concrete was found. The very high strength of basalt did not contribute to the highest strength of concrete with basalt aggregate, and the modulus of In general, rock mass strength depends on the strength of intact rock and the strength of rock discontinuities. In general, compared to intact rock, a rock mass has STRENGTH PROPERTIES OF ROCKS AND ROCK MASSES

Basalt Properties, Formation, Composition, Uses Geology
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.Crushing Strength.

Engineering properties of basalt aggregates in terms of use
Basalt comes to the fore with its high tensile strength, high resistance on Na 2 O+K 2 O and SiO 2 contents according to Le Maître [24] it was determined that the materials belonged to the trachy-basalt and basalt rock. The Loss of Ignition (LOI) was found at a rate of 3–5%. and structure and partially on the crushing techniqueBased on abundant test data, Li et al. 16 concluded that the relationship between rock crushing strength and strain rate is \(\sigma_{d} = A\dot{\varepsilon }^{B}\), where B is about 0.3, whileDynamic response characteristics and damage rule of graphite ore rock

Materials Free Full-Text Influence of Basalt Aggregate Crushing
Basalt 1 had a tuff content of less than 5%, while basalt 2 had a tuff content of about 15%. Volcanic tuffs are characterized by lower fragmentation and wear resistance; hence, a rock material with a higher content of tuffs and basalt weathering will have lower strength parameters after the crushing process. Figure 1 illustrates the materialThe crushing strength of the aggregate was determined using the aggregate crushing value (ACV) to PN-B w/c = 0.58 c) w/c = 0.45 d) w/c = 0.28 * Due to the high strength of the basalt rock and the high compressive strain in the granite rock at peak stress, the curves for these rocks are shortened; the values of compressive strengthStress-strain relationships and modulus of elasticity of rocks

Basalt are igneous rock that possess low silica content. They are dark This process consists of two subsequent crushing operations. First, the basalt rock is moved into the jaw crusher by a vibrating feeder to maintain primary crushing. Such preprocessed rock is fed to a cone crusher for secondary crushing.
