Abstract:

In this study, the usability of limestone extracted from two different aggregate quarries located in Çankırı province as concrete aggregate was investigated. For this purpose, aggregate samples were taken from the two quarries and on the samples taken, sieve analysis, specific gravity, water absorption, bulk density, very fine material content, flakiness index, methylene blue, disintegration strength, abrasion resistance, freeze-thaw, alkali-silica reactivity, acid soluble sulfate and total sulfur tests were carried out. As a result, the results of the tests performed on aggregates obtained from the limestone quarries around Çapar village (Şabanözü, Çankırı), Seydiköy (Eldivan, Çankırı) and Doğu district (Korgun) were compared with the limit values given in the standards and the usability of these limestone as concrete aggregates was determined. According the tests performed on the aggregates it can be clearly seen that, that all properties of these aggregates are suitable according to the EN standards.
