Using of Recycled Aggregate in Producing Concrete Elements

This thesis aimed to find the potential of using recycled aggregate as course aggregate in the production of concrete blocks and interlocks for roads. Various percentages of recycled aggregate and natural aggregate (0%, 30%, 60% and 100%) and different water cement ratios ( 0.35, 0.42, and 0.50 ) were used to find

Recycled Concrete as Aggregate for Structural Concrete

Recycled concrete aggregate (RCA) is generally produced by two-stage crushing of demolished concrete, and screening and removal of contaminants such as reinforcement, paper, wood, plastics and gypsum. Concrete made with such recycled concrete aggregate is called recycled aggregate concrete (RAC). The main purpose of this work is to determine

MASTER’S THESIS

Once the concrete mixture is ready, it is transported to the work site. There are many methods of transporting concrete, including wheelbarrows, buckets, belt conveyors, special trucks, and pumping. Pumping transports large quantities of concrete over large distances through pipelines using a system consisting of a hopper, a pump, and the pipes.

Ball mill Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T
