Expansive clays undergo swelling when subjected to water. This can cause damage, especially to light weight structures, water conveyance canals, lined reservoirs, highways, and airport runways unless appropriate measures are taken. In this study, granulated blast furnace slag (GBFS) and GBFScement (GBFSC) were utilized to overcome or to limit the expansion of an artificially prepared expansive soil sample (sample A). GBFS and GBFSC were added to sample A in proportions of 5-25% by weight. The effects of these stabilizers on grain size distribution, Atterberg limits, swelling percentage and rate of swell of soil samples were determined. GBFS and GBFSC were shown to successfully decreasing the total amount of swell while increasing the rate of swell.

Stabilization of expansive clays using granulated blast furnace slag(gbfs), gbfs-lime combinations and gbfs cement Yazıcı, Veysel; Çokça, Erdal; Department of Civil Engineering (2004) Expansive clays undergo a large swell when they are subjected to water. Thus, expansive clay is one of the most abundant problems faced in geotechnical engineering applications. It causes heavy damages in structures, especially in water conveyance canals, lined reservoirs, highways, airport runways etc., unless appropriate measures are taken. In this thesis, Granulated Blast Furnace Slag (GBFS), GBFS - Lime combinations and GBFS Cement (GBFSC) were utilized to overcome or to limit the expansion of an artifi...
Effect of Fly Ash on Swell Behaviour of a Very Highly Plastic Clay Çokça, Erdal; Lav, Musaffa Ayşen (2018-08-16) Swelling of expansive soils causes excessive heave. Resulting expansion can lead to considerable distress to pavements and/or lightweight structures which are settled on that kind of subsoils. Several methods can be applied to control the swelling problem. One of the most commonly used method is the addition of stabilizing agents, such as lime or fly ash to the expansive soil. Soil samples that are very highly plastic have been taken from clay deposits of Ankara in Turkey in this study. Both disturbed and u...
Prediction of swelling potential of Ankara soils by methylene blue test Çokça, Erdal (Scientific and Technical research Council of Turkey - TUBITAK/Turkiye Bilimsel ve Teknik Arastirma Kurumu, 1993-01-01) The swelling potential characteristics of Ankara soils by using different swelling potential classification methods developed by different researchers were investigated. The influence of the mineralogical composition of swelling potential of expansive clay soils and the use of Methylene Blue Test in order to predict their swelling potential were studied. A swelling potential classification method has been proposed by using clay content versus methylene blue value chart.
Recovery of brackish water from reactive dyeing wastewater by ultrafiltration Erkanlı, Mert; ZAF, RUKEN DİLARA; Yılmaz, Levent; Çulfaz Emecen, Pınar Zeynep; Yetiş, Ülkü (2017-02-06) In this study, brackish water recovery from a real reactive dyeing textile effluent for reuse of water and salt was investigated. With the aim of improving the overall retention of species that are partly retained in a single stage, three different two-stage ultrafiltration scenarios were considered: 5 kDa followed by 5 kDa, 5 kDa followed by 2 kDa and 2 kDa followed by 2 kDa. The 2 kDa + 2 kDa scenario reduced the total organic carbon (TOC) from 239 +/- 9 mg/L to 41 +/- 7 mg/L, at 2 bar of transmembrane pr...
SETTLEMENT OF WEAKLY CEMENTED TUFAS DİPOVA, NİHAT; Ergun, Mehmet Ufuk; Vedat, Doyuran (2014-01-01) Weakly cemented tufas are sand and silt size soils that are weakly bonded with thin films of carbonate cement. The void ratio is rather high and equal to approximately 1.2. Collapse occurs as a result of the destruction of the weak bonds upon loading and/or wetting. The index properties and the collapse potential (C-p) of tufa were determined in the laboratory. In the determination of the collapse-potential values the single-ring oedometer method was considered to be a suitable and simpler tool. In plotting...
