abstract and figures. the results of a test programme to study the use of recycled concrete aggregate (rca) in high-strength, 50 n/mm2 or greater, concrete are described. the effects of coarse rca
the properties were evaluated in the first cycle (rgp-1) and the third one (rgp-3). b. recycling process the recycling process was made by grinding and burning the waste (gpw). the gpw was crushed in a ball mill reaching a fineness modulus of less than 1.10, homogenized and burned in a stationary oven at 150 c for 1hour. c.
this short communication focuses on the potential use of paper sludge ash in alkali-activated cement concrete this type of concrete was estimated to potentially reduce co 2 emissions by up to 56 times, while it can also incorporate waste materials or industrial by-products in its composition. the paper presents a laboratory study assessing
using ball mill to produce slag fine powder, the fineness adjustment is more flexible, and the particle shape and gradation are better, but the power consumption is higher. with the expansion of the scale of industrial production, the emissions of waste stone, tailings and slag are rising linearly, and a large number of industrial solid waste
coming from a batch where the size distribution the recycled concrete was first sieved (with sieve openings of 4mm, 2mm, 1mm, 0.5mm, 0.212mm, 0.125mm, 0.063mm) before being dehydrated at 550c. or 750c, then some of the material was softly milled in planetary ball mill in order to break hardened cement paste.
