TL;DR: In this paper, a comprehensive study on the application of Class F fly ash for stabilizing subgrade soils in Taiwan is presented, where Lime (or cement) was used with fly ash to enhance its self-cementing behavior in the study.
Abstract: A comprehensive study on the application of Class F fly ash for stabilizing subgrade soils in Taiwan is presented. Lime (or cement) was used with fly ash to enhance its self-cementing behavior in the study. Laboratory testing included using the plasticity index method to determine the optimum percentages of additive and fly ash. Through a resilient modulus (M sub r) test program, these percentages were confirmed. A section of test road with treated subgrade constructed on the West Coast Highway has been open to traffic for 40 months to date. A field investigation of this section was part of this study. Results from field California bearing ratio tests indicate that treatment of the subgrade soil had improved its properties by a factor of 10 to 15. Specimens obtained from the field were also evaluated through an M sub r test program, and the results were compatible with those for laboratory-made samples. Finally, a microstructure study is presented showing significant cementitious materials in laboratory and field specimens. Confidence about the future application of Class F fly ash for stabilizing subgrade soils in Taiwan and for handling this problematic waste material is provided.

TL;DR: In this article, the authors presented a method to compute wave height and run-up in the presence of rapid flow and showed that the use of a thin llayer of CEMENT GROUT at the interface of the contours will reduce the see-through flow.
Abstract: LABORATORY TESTS MADE TO OBTAIN DESIGN FACTORS FOR THE APPLICATION OF SOIL-CEMENT IN EARTH DAMS AS SLOPE PROTECTION, IMPERMEABLE BARRIERS, AND AS AN EROSION- RESISTANT SURFACE IN AREAS OF RAPID FLOW ARE REPORTED. THE STABILITY OF EMBANKMENTS CONSTRUCTED WITH CEMENT-STABILIZED SOILS IS ALSO CONSIDERED. SEVERITY OF CLIMATIC EXPOSURE GOVERNS THE AMOUNT OF CEMENT REQUIRED TO STABILIZE SOIL USED FOR SLOPE PROTECTION. THE CURRENT PRACTICE OF INCREASING THE CEMENT CONTENT 2 PERCENTAGE POINTS ABOVE THAT REQUIRED BY STANDARD TESTS IS DESIRABLE WHEN THE FACING IN THE SPLASH ZONE IS EXPOSED TO FREEZING. IN MILDER EXPOSURES, STABILIZATION WITH THE MINIMUM AMOUNT OF CEMENT REQUIRED TO MAKE SOIL-CEMENT MAY BE CONSIDERED. WHEN SLOPE PROTECTION IS EXPOSED TO RAPID FLOW CARRYING STONES OR DEBRIS, THE HIGHER CEMENT CONTENT AND AT LEAST 20 PERCENT GRAVEL SHOULD BE USED IN THE SOIL-CEMENT. SOIL-CEMENT SLOPE PROTECTION CONSTRUCTED IN STEPPED LAYERS WILL LESSEN WAVE RUN-UP AS COMPARED TO RUN-UP ON SMOOTH EMBANKMENT SLOPES. METHODS TO COMPUTE WAVE HEIGHT AND RUN-UP ARE PRESENTED. INCREASES IN SLOPE STEEPNESS RESULT IN HIGHER RUN-UP. SEEPAGE THROUGH DAMS CAN BE REDUCED BY CONSTRUCTION OF SOIL-CEMENT UPSTREAM BLANKETS, CORE WALLS, OR CUTOFF TRENCHES. SEEPAGE FLOW IN THE DIRECTION PERPENDICULAR TO LAYERING DUE TO CONSTRUCTION IS CONSIDERABLY LESS THAN FLOW PARALLEL TO LAYERING. THE USE OF A THIN LAYER OF CEMENT GROUT AT THE INTERFACE OF THE COMPACTION PLANES WILL REDUCE SEEPAGE SIGNIFICANTLY. /AUTHOR/

TL;DR: In this paper, the authors discussed the possibility of using Portland cement as the stabilizing agent for dune sands soil stabilization, and the results indicated that mixing dune sand with cement stabilizing agents would influence the engineering properties of treated soil.
Abstract: When designing and constructing highways or more generally any super structures on dune sands type of soil, it is essential to make sure that the foundation soil is stable and provides good support to the applied loads. Dune sands soil are known to spread in huge areas throughout the kingdom of Saudi Arabia in which thousands of miles of new roads and highways are being constructed everyyear. Replacing such kind of weak soil is not an economically feasible alternative since it is very costly; besides, the replacement soil is not always available in nearby sites. This study discusses the possibility of dune sands soil stabilization using Portland cement as the stabilizing agent. Various ratios of cement content mixed with dune sands are used to examine the improvement of engineering properties of dune sands in terms of strength characteristics, and shear strength parameters. The results indicate that mixing dune sands with cement stabilizing agents would influence the engineering properties of treated soil. It is determined that the cement stabilization of dune sands improves the strength characteristics of the treated soil so that it becomes usable as a base material for roads construction and proper foundation material for other types of super structures. It was also determined that a cement content more than 9% may not probably cause any additional improvement for the stabilized soil. A suggested relationship is introduced to predict the values of initial tangent elastic modulus for such type of cement-treated dune sands. Key words: Dune sands, Cement stabilization, soil improvement, Shear Strength Parameters.

TL;DR: In this paper, the effect of industrial wastes on the strength development of stabilized soils was investigated by using X-ray diffraction (XRD) and scanning electron microscopy (SEM) methods.
Abstract: This paper describes the effective utilization of industrial wastes such as ferric oxide powder and aluminum sludge for soil stabilization. Mixing these industrial wastes with hydrated lime to form some new type of stabilizers will be useful for both strength improvements of soils and environmental protection. The primary objective of this study is to investigate the effect of wastes on the strength development of stabilized soils. To perceive the strength development mechanisms of stabilized soils, X-ray diffraction (XRD) and scanning electron microscopy (SEM) methods were employed in order to evaluate the formation of chemical reaction products and microstructural changes occurred in the stabilized soils. The industrial wastes contained in stabilized soil improve the mechanical properties of soils by chemical reactions between the reacting elements of industrial wastes and clay minerals in the soil. In particular, adding aluminum sludge into ferrum lime lead to a marked improvement in the early strength or flexural strength of stabilized soils.
