The crushability, grindability, and cutability of rocks are associated with many factors. During the size reduction processes in a jaw crusher and rod mill, crushing and grinding energy consumption increase when finer size fractions of the product are desired (Zeng and Forssberg 1992).Heikkilä (Heikkila 1991) reported that the lithological features …

Samples made during mechanical grinding, i.e., treated recycled aggregate (TRA), were divided into two parts, 4.75–10 mm and 10–25 mm. The concern of gradation is often related while using RA. To solve these concerns related to RA's gradation and particle size distribution, the job mix formula was used to achieve the desired concrete grade ...

Polishing and Grinding Concrete. There are a range of finishes possible from a single piece of concrete. A deep polish will expose more of the large aggregate in the mix, while a light polish will only expose the small specks of sand. A consistent and uniform finish can be achieved by simply burnishing the surface.

The treatment method was based on the mechanical grinding of the adhered mortar from the surface of the RCA. The aggregates were placed inside a 100 L capacity concrete drum mixer along with water, where the rotating motion allowed the aggregates to collide with each other and with the metal walls of the drum. The collision …

As waste plastic materials have lower bulk density (HDPE plastic: 930–970 kg/m3, PET: 1270 kg/m3) than natural aggregates (2450-2570 kg/m3), increase in the content of plastic aggregate reduces both fresh and dry density of concrete: the reduction is greater with bigger and flakier particles of plastic aggregate. Mechanical properties.
