بەڕێوەچوونی سمینار

لە دڕێژەی کار و چالاکییەکانی فاکەڵتییەکەمان، ڕۆژی سێشەممە ٢٠٢١/٦/٨، کاتژمێر (٩)ی شەو، سمینارێک بە شێوەی ئونلاین لە لایەن  "م. ئاریانفەر حاجی شێروانی" مامۆستای بەشی ئەندازیاری شارستانی بە ناونیشانی: Strength, Abrasion Resistance and Permeability of Artificial Fly-Ash Aggregate Pervious Concrete پێشکەش بە ژمارەیەکی بەرچاو مامۆستایان کرا. 

پۆختەی سمینار:
The objective of this study is to utilize artificial cold bonded fly ash aggregate (AFA) in pervious concrete to produce a sustainable, and permeable concrete. The AFA were manufactured through cold bonding pelletization of fly ash (90%) and Portland cement (10%) in an inclined pan at ambient temperature. In this study, pervious concrete is manufactured by replacing the natural aggregates (NA) with AFA in five levels of replacements 0 to 100% with 25% increments of the total aggregate’s volume. Two different concrete series were manufactured at 0.27 and 0.32 water-to-cement ratios (w/c). Totally, 10 pervious concretes were manufactured in this study. The utilized NA and AFA were uniformly graded and ranged 12.5 mm to 8 mm. In this study, the dry density and content of voids were determined. Furthermore, for the produced pervious concretes some tests were conducted such as compressive strength, splitting   tensile, permeability and abrasion resistanc
