Öğütülmüş
kumlar, özellikle şişme eğiliminde olan killerin iyileştirilmesinde
kullanılmaktadır. Her kum kendine özgü fiziksel özelliklere sahiptir. Bu
nedenle kullanılan kumun mühendislik özelliklerinin belirlenmesi gerekmektedir.
Bu çalışmada farklı mineralojiye sahip 4 kum kullanılmıştır. Bu kumların
mühendislik özellikleri belirlendikten sonra, kil ve silt boyutuna kadar
öğütülerek her numuneden farklı tane dağılımlarına sahip, 3’er numune elde
edilmiştir. 12 kumun “Kötü derecelenmiş kum” olduğu, farklı mineralojiye sahip kumların
fiziksel özelliklerinin de farklı olduğu belirlenmiştir. Türevler içinde en
büyük farklılık magmatik kökene sahip Tip 1 kumunda görülmüştür. Sonuç olarak,
kumların, tane boyutlarının küçülmesiyle mühendislik özellikleri
değişmiştir. Ayrıca farklı mineralojiye sahip kumların öğütülmeleriyle elde
edilen türevlerin farklı davranışlar sergiledikleri belirlenmiştir.

A COMPARISON OF QUARTZ SANDS WITH DIFFERENT MINERALOGY AND THEIR GRIDING DERIVATIONS

Öz

Griding sand is
specifically used to treat clays that tend to swell. Each of the sands has its
unique physical properties. For that reason, it is necessary to determine the
engineering properties of the sand used. In this study, four types of sand with
different mineralogy were examined. After determining the engineering
properties of these sands, three different specimens per sample, with different
size distributions, were obtained by grinding them up to the size of clay and
silt. As a result, it was determined that the twelve sand samples consisted of
poorly sorted sand and the physical properties of the sands with different
mineralogy were different to each other. The largest difference in derivatives
was found in Type 1 sand of magmatic origin. It was observed that the original
sand used in all experimental results gave higher values than the finer grained
derivative samples. As a result, the engineering properties of the sands
changed with the reduction in grain sizes. In addition, it was determined that
the derivatives obtained by grinding the sand with different mineralogy exhibit
different behaviors.
