The mechanical properties of concrete investigation impact strength effects

Concrete strength is understudied as pressure and tensile strength furthermore it is expose to impact apart from these. Despite of the fact that factors effecting on pressure and tensile strength have been studied completely, on the impact strength hasn?t been studied.In this study; pressure as from properties mechanics of concrete, flexural strength and tensile splitting strengths were analyzed effects on impact strength. In accordance with this purpose; effecting on impact strengths of aggregate size and water/cement (W/C) rate in mixture were prepared six series total as aggregate size 4-8, 16 mm and being water/cement (W/C) rates 0.5, 0.55. In accordance with this purpose; pressure, flexural strength, tensile splitting strength and values of ultra sound were determined experimentally. Moreover fracture energy and impact strengths of every series were determined via Charpy impact experiment in order to compare other mechanic purposes of concrete with impact strength. Relation between tensile strength and other mechanic properties of concrete was studied via analysis of getting dates.Results of this study; with increase of values of dmax was increase strengths. Pressure, impact and tensile strengths were increase approximately same rates. Pressure and tensile strengths were decrease approximately 20% rates because of increase at the rate of water/cement (W/C). But decrease at the impact strengths is value 5%
