Abstract

In this study, the effect of quantity of sodium hexametaphosphate (NaPO3) to the soil grain’ diameters were investigated as experimental and statistically. Hydrometer testing was conducted. 0, 10, 20, 30, 40, 50 and 60 gr NaPO3 was respectively added into the prepared suspension. The specific gravity, pH and the conductivity were measured for each suspension. As pointed out in the TS 1900-1-2006 (Turkish Standard), the soil’ grain diameter in the solution prepared with 40 gr NaPO3 was used as reference. As a result, it was determined that the soil grain diameter in suspension added “0” gr NaPO3 greater 4.51 time than the reference grain diameter. When respectively added 10 gr into the suspension, the soil’ grain diameter greater 3.90 time than reference grain diameter, added 20 gr 3.46 time, and added 30 gr 2.12 time. Besides, the hydrometer reading could be done only 260th minute when added 50 gr in to the suspension. Moreover, the hydrometer couldn’t be read in the solution prepared with 60 gr NaPO3. The obtained data were analysed statistically by using SPSS programme and determined the correlation coefficients for the hydrometer test parameters (passing time, original hydrometer reading, temperature, pH, conductivity, The correction coefficient value for solving matter and temperature, corrected hydrometer reading, effective deep, value of the K, particle diameter and quantity of the NaPO3). Also, regression analysis was conducted (R=0.87) to predict the corrected hydrometer test reading based on the original hydrometer reading and the quantity of the NaPO3.

Özet

Bu çalışmada, hidrometre deyinde kullanılan sodyum hegzametafosfat (NaPO3) miktarının zeminin tane çaplarına etkisi deneysel ve istatistiksel olarak incelenmiştir. Hidrometre deneyleri için hazırlanan süspansiyonlara sırasıyla 0, 10, 20, 30, 40, 50 ve 60 gr NaPO3 ilave edilmiştir. Bu şekilde hazırlanan her bir süspansiyonun özgül ağırlığı, pH değeri ve iletkenliği ölçülmüştür. TS1900–2006’ da belirtildiği gibi 40 gr NaPO3 kullanılarak hazırlanmış olan süspansiyondaki zemin tane çapları referans değer olarak kullanılmıştır. Sonuç olarak, süspansiyonda hiç NaPO3 kullanılmadığında elde edilen tane çaplarının referans tane çaplarından 4.51 kat, 10 gr için 3.90 kat, 20 gr için 3.46 kat, 30 gr için 2.12 kat daha büyük olduğu tespit edilmiştir. Buna karşılık 50 gr kullanıldığında ise sadece 260’ncı dakikada hidrometre okuması yapılabilmiş ve 60 gr kullanıldığında ise hidrometre okuması yapılamamıştır. Deney sonuçları kullanılarak SPSS programı ile istatistiksel analizler yapılmış ve hidrometre deney parametreleri (geçen süre, ilk hidrometre okuması, sıcaklık, pH, iletkenlik, ayrıştırıcı madde ve sıcaklık düzeltme katsayısı, düzeltilmiş hidrometre değerleri, efektif derinlik, K değeri, tane çapı, süspansiyonun özgül ağırlığı ve NaPO3 miktarları) arasındaki korelasyonlar belirlenmiştir. Ayrıca regresyon analizi yapılarak ilk hidrometre okumasına ve NaPO3 miktarına bağlı olarak düzeltilmiş hidrometre okuması için tahmin modeli oluşturulmuştur (R=0.87).
