Impact strength of leightweight pumice, volcanic slag and boiler bottom slag aggregate-characterizat?on strength of leight weight concrete

Tatvan pomza, volkanik c?ruf ve ??rnak Kazan c?ruf agrega numuneleri bas?n? dayan?m? ve darbe shatter dayan?m? testine tabi tutulmu? ve ?r?n hafif betonun mekanik dayan?m? irdelenmi?tir. -40mm+25mm boyutundaki hafif agrega numuneleri sabit 5kg luk darbe balyoz a??rl???n?n 500*?80 kovanda d??me etkisi ile ?r?n boyutunun ufalmas? ve toz la?mas? olarak belirlenmi? ve ?r?n hafif beton bloklar?n basma dayan?m? ile k?yaslanm??t?r. B?ylelikle g?zenekli hafif agregalar?n dayan?m de?erleri daha ?nceden 22 adet agrega numunesi ile belirlenmi? ideal dayan?m ?ablonu ?zerinde tan?mlanm??t?r. Bu ?al??mada 3 adet hafif agrega numunesinin dayan?mlar? 7,2 den 18,4 MPa ??km??t?r. Darbe shatter dayan?m de?erleri %38 ile %74 aras?nda de?i?mi?tir. Hafif beton yap? bloklar? %50 oranlar?nda volkanik c?ruf, pomza ve taban c?ruflar? ile ayr?ca harmanlanm??, ?r?n betonun dayan?m? 28g?nl?k k?r sonunda %30 hacim ?imento oran?nda 17,4MPa ula?m??t?r.The impact shatter strength and compression strength of aggregates of Tatvan pumice, volcanic slag and ??rnak boiler slag were determined and interrelated with the compression strength of regarding leightweight concrete. -40+25mm aggregates are subjected to impact load of 5kg hammer drop at 50cm height in the 500*?80 steel barrel and the results ere discussed with the strength of leightweight concrete. Strength values of aggregates were defined on a drawn pattern previously determined with 22 aggregate rock samples, the strengths of 3 diffrent porous aggregates studied changed from 7,2MPa to18,4MPa. Impact shatter resistance varied between 38% to 74%. The mixtures of volcanic slag and boiler slag aggregates were also investigated in lightweight concrete production. The strength of products at 28 curing period and 30% cement addition reached to17.4 MPa strength
