“…The usual fate of this sand -several MT per year -is to be landfilled after a previous process of solidification/stabilization. Owing to high landfilling costs and environmental concerns, some researchers have reported other management alternatives for these polluted WFS, such as subbases, soils, ceramics, controlled-low-strength materials and concretes [4][5][6][7][8]. In these last two cases, WFS can be used to partially replace normal sand.…”

“…Different issues related to this last point have been addressed: the effect of WFS on workability and compressive strengths, the freezing-thawing resistance of the concretes and the replacement levels [9][10][11]. In general, only low replacement levels (below 20%) guarantee acceptable performance in the final concrete [5].…”

“…The finest sand fractions cannot be reused and constitute waste mass directed to landfills, the main component of WFS. Studies have shown that is possible to utilize WFS in high-strength, normal and low-strength concrete and WFS can positively impact their mechanical properties [2][3][4][8][9][10][11][12][13][14][15][16].…”

“…Tane boyutu dağılımı uniform ve % 85-95'i 0,6 mm ile 0,15 mm arasında, % 5-12'si ise 0,075 mm'den küçük olmalıdır. Döküm kumunun özgül ağırlığı ise 2,39 ile 2,55 arasında ve su emme kapasitesi düşük olması gerekmektedir (Başar ve Aksoy, 2012). Nehir, deniz, çöl, eski göl ve dere yataklarından elde edilen agregalara (kum ve çakıllar) doğal agrega denir.…”
