In this study of methods to rationally remove the surfaces of concrete members contaminated with radioactivity, concrete members were irradiated with electromagnetic waves and were examined for the speed of destruction, depth and efficiency of the concrete and the effectiveness of the method of demolishment.
impact crushing. Abrasion crushing (or, more correctly, attrition), uses friction and compression to fracture material and includes equipment such as jaw crushers and cone crushers. Because of the highly abrasive nature of glass, impact-crushing equipment is preferred over abrasion crushing for greater durability and more uniform shape.
So, Fig. 3 clearly shows that crushing with an ultra-turrax is the most efficient method for the removal of microorganisms from both peat and activated carbon. In addition, RSD for the crushing method (10%) was lower than those observed for ultrasonic (20%) and shaking (30%).

A new method was presented to prepare activated carbon fiber with high bulk density (HD-ACF) without using any binders. The method consists of the hot briquetting of stabilized fiber and subsequent carbonization and activation of the fiber. The stabilization level of the stabilized fiber usable in this method must be higher than that of …
The adsorption method is widely used for the treatment of aqueous media contaminated by organic pollutants [5], [6]. Activated carbon is the main adsorbent used due its easy application and efficiency; however, the production cost of this adsorbent can be affected by the source and price of the raw material [7], [8]. Therefore, the use of low ...
This paper investigates the particle breakage behaviour of a carbonate sand based on single-particle compression experiments with in situ X-ray microtomography scanning (μCT) and a combined finite–discrete element method (FDEM). Specifically, X-ray μCT is applied to extract the information on grain morphology and intra-particle pores of …
