Due to the increasing presence of problematic soils, expansive clays and highly compressive sand engineers are using a verity of soil improvement techniques to treat such soils. While geosynthetics are extensively used for improving soil characteristics in roads, pavements and embankments, it can also be used to increase the lack of bearing capacity of residential housing or lightweight structures constructed on sandy soils. In order to simulate site conditions in the laboratory environment, a laboratory-scale testing platform has been manufactured to assess the behaviour of geosynthetics reinforced and un-reinforced strip footing. The first group of tests were performed on the unreinforced compacted sandy soils with different densities where the other group of tests were carried out in the soil that has been reinforced individually with three different types of geosynthetic materials having distinct tensile strengths. Furthermore, interface direct shear tests and consolidated undrained triaxial tests have been carried out to determine the shear parameters which is directly influencing the bearing capacity a strip footing. Geosynthetic reinforcement has considerably enhanced the mechanical behaviour of sandy soil in regarding the type of geosynthetic. Furthermore, it was observed that coir geosynthetic has provided increased interfacial friction when compared to other geosynthetic types and improved bearing capacity. Moreover, the adopted testing method found to represent well the behaviour of such materials in the laboratory environment.

Effect of chemical and mineral admixtures on the fresh properties of self compacting mortars
Christianto, Heru Ari; Yaman, İsmail Özgür; Department of Civil Engineering (2004)
Fresh properties of mortars are important factors in altering the performance of self compacting concrete (SCC). Measurement of the rheological properties of the fine mortar part of concrete is generally used in the mix design of SCC. It can be stated that SCC rheology can be optimized if the fine mortar part of concrete is designed properly. However, measurement of the rheological properties is often impractical due to the need for complex equipment. Therefore, more practical methods of assessing mortar wo...
EFFECTS OF SPATIAL VARIABILITY OF MARGINAL FILLS ON EXTERNAL STABILITY OF REINFORCED SLOPES
Durmaz, Muhammet; Huvaj Sarıhan, Nejan; Turgut, Atalay Mert; Öztürk, Nur (null; 2019-11-15)
Geosynthetic reinforced soil walls and slopes are typically designed using clean granular fills. In recent years, granular soils containing some percentages of fines content (marginal fills) are being used, e.g. 35% fines content is allowed in the granular fill by NCMA (2006), provided that sufficient drainage measures are taken. Designing with granular soils that can have variable proportions of fines content, leads to the consideration of variability of soil properties such as shear strength and unit weig...
Effect of Foundation Soil Stiffness on the Seismic Performance of Integral Bridges
Dicleli, Murat (Informa UK Limited, 2011-05-01)
In this study, the effect of foundation soil stiffness on the seismic performance of integral bridges (IBs) is investigated. For this purpose, nonlinear structural models of a two-span TB with four different foundation soil stiffness types (loose, medium, medium-dense and dense sands) are built. In the nonlinear structural models, nonlinear soil structure interaction including free-field effects is considered. Then, the nonlinear time history analyses of the TB models are conducted using a set of ground mot...
Effect of material characteristics on the properties of blended cements containing high volumes of natural pozzolans
Turanlı, Lutfullah; Uzal, B; Bektas, F (Elsevier BV, 2004-12-01)
The effect of three different natural pozzolans from Turkish deposits on the properties of blended cements produced by intergrinding cement clinker with a high volume of natural pozzolan (55 wt.% of the cementitious material) was investigated. The particle size distribution of blended cements, setting time, heat of hydration, and compressive strength of blended cement mortars were determined. Experimental results showed that the hardness of the pozzolanic material strongly influenced the particle size distr...
Effect of alkali-silica reaction expansion on mechanical properties of concrete
Hafçı, Alkan; Turanlı, Lütfullah; Department of Civil Engineering (2013)
Alkali-silica reaction (ASR) is a chemical deterioration process which arises in concrete due to reactive aggregate from its constituent, sufficient alkalis from cement or external resources and humidity about 85%. ASR gel, formed by the reaction, absorbs water and expands so that it causes expansion and cracking in concrete. ASR has detrimental effects on mechanical properties of concrete. Therefore, ASR which is a long and a constantly progressive reaction may become a threat to the safety of concrete str...
