Özet:

Concrete is one of the most important building materials in today's construction industry. Concrete material has important problems. The first of these problems is the supply of quality aggregate and the second is the environmental pollution and sustainability of construction wreck wastes. Concrete was produced by using a hyper plasticizer in different proportions, using crushed sand (KK) and natural sand (DK) as fine aggregate and coarse aggregate obtained from construction wreck waste (YAA). YAA (4-11.2) 24%, (11.2-22.4) 29% and fine aggregate DK and KK (0-4) 47% were used as aggregate in the concrete mixture. Concrete was produced by using CEM I 42.5 R cement as the binder and the amount of hyper plasticizer at 0%, 1%, 1.5% and 2% of the cement weight. Workability, compression and splitting tensile strength, abrasion, capillary water absorption rates and length changes of the concrete produced were observed. It has been observed that the workability of concrete produced with DK used in addition to YAA is high, while other mechanical and physical properties show the lowest properties of the study. Although the workability of the concrete mixture produced with KK has decreased, it has been determined that the mechanical and physical properties of the work have the highest performance values
