Influence factors for using hydraulic binders for soil stabilisation of fine-grained soils in cold environment

چکیده
Abstract The stabilization of soft soils with hydraulic binder is a common technique all over the world. By means engineering properties fine-grained can be improved, where settlements or stability problems have to handled. Lime and cement are usual binders. use industrial by-products as binders has been investigated some already established on market in combination cement, e.g. fly ash slag. Nowadays reduction CO 2 focus, leading search for more from industry that suitable binder. One these kiln dust (CKD) started used commercially cement. Fine-grained often frost susceptible i. e. they show heave and/or thaw weakening. These typical handled by improvement countries moderate climate [33]. In cold climate, near surface soil less used. reason this reduced usage uncertainties about influence low temperature expected stabilizing effects Previous research shown strength stabilized material decreased impact, when compared without frost. New results recovering after due [1; 2]. present contribution, multiple linear regression analysis presented identifying significant influencing factors subgrade environment. based three earlier published laboratory studies [3-5], unconfined compressive (UCS) was measure strength. involved different types, (mainly by-products), varying contents. increases during curing After twelve freeze-thaw-cycles several samples, freeze-thaw-cycles, but it higher than stabilization. A subsequent time visible cases samples. here shows content, well time,

Soil Compression Index Prediction Model for Fine Grained Soils
Compressibility of a soil mass is its susceptibility to decrease in volume under pressure and is indicated by soil characteristics like coefficient of compressibility, compression index and coefficient of consolidation. However, the determination of soil compressibility characteristics in the labs is a cumbersome and time consuming process, especially in the case of fine grained soils. In the p...

در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
15 صفحه اولCPT-based evaluation of liquefaction potential for fine- grained soils
Recent ground failure case histories after 1994 Northridge, 1999 Kocaeli and 1999 Chi-Chi earthquakes revealed that low-plasticity silt-clay mixtures generate significant cyclic pore pressures and can exhibit a strain-softening response, which may cause significant damage to overlying structural systems. In this study, results of cyclic tests performed on undisturbed specimens of ML, CL, MH and...
متن کاملSmall Strain Stiffness of Fine Grained Soils
Dynamic measurements of very small strain stiffness (c 0.001% and less) were carried out both in the laboratory, using piezoceramic bender elements of the type developed at the Norwegian Ceotechnical Institute and at the University College of North Wales, and in situ, using surface wave techniques. For the purpose of the research described in this dissertation, the piezoceramic bender elements ...
