Dec 01, 2020· Very good properties of concrete with basalt aggregate, in addition to the best crushing strength of this aggregate, may also result from the micro-roughness and angularity of basalt grains. In turn, granite contains large quartz crystals with a smooth, shell-like breakthrough, which can significantly reduce the strength of concrete.

Difficulties of basalt crushing and processing. 1. Basalt has high compressive strength, good rock toughness, high hardness, strong abrasiveness, and great difficulty in crushing, which makes it difficult for the actual processing capacity of the crushing equipment to reach the theoretical output capacity. 2.

Basalt and diabase are materials with higher hardness and higher silicon content. It is more difficult to crush in actual crushing operation, at the same time the crushing cost is high. For basalt crushing, multi-stage crushing equipment should use as much as possible to reduce the loss of wear parts.

The crushing strength test results are presented in Tables 3 to 5, the strength reduces with the increase in the size of aggregate. At 7 days curing, the strength of fly ash aggregate (30G2) was enhanced by 41 % higher compared to that of 1 day curing. The crushing strength of 6 mm size of fly ash aggregate (30G2) showed an increase of 17.36%.

The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30-40%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to decay, strength and

Based on dynamic triaxial experimental results for basalt fibre-reinforced coral aggregate concrete (BFRCAC), the dynamic Mohr–Coulomb (M − C), Hoek–Brown (H–B), and Drucker–Prager (D–P) strength criteria for BFRCAC are established. The results show that the dynamic strength of BFRCAC increases with an increase in the
