Improvement of Strength Characteristics of a Highly Plastic Expansive Soil with Fly Ash
نویسندگان
چکیده
Highly plastic expansive clays swell or shrink due to change in moisture content and they often have very low bearing capacity. Construction of engineering structures particularly pavements lightweight buildings on problematic soils such as highly may create severe structural problems poor properties that kind soil. This study focused the influence fly ash strength which are their undesirable characteristics high plasticity index, liquid limit, swelling shrinkage characteristics, Atterberg’s limit tests hydrometer were conducted obtain consistency limits grain-size distribution clay. Standard proctor for clay samples with different contents 10%, 15%, 20% performed determine maximum dry densities optimum water mixtures ash. The prepared at density unconfined compression (UCS) California Bearing Ratio (CBR) tests. Effects fly0ash a investigated through CBR experiment results showed is promising additive enhance clays. An approximately 66% increase UCS values was observed addition into mixture weight.

Shear Strength Characteristics of Fiber Reinforced Fly Ash
Disposal of an industrial waste like flyash produced from burning of coals in thermal power stations requires a large land area. The decreasing availability of good construction site has led to the increased use of low lying areas filled up with industrial wastes whose bearing capacity is low. In-situ treatment of such industrial waste fills; in order to improve their bearing capacity with rein...
متن کاملStudy on Strength Behavior of Organic Soil Stabilized with Fly Ash
The aim of this study is to investigate the effect of fly ash on the consistency, compactness, acidic properties, and strength of organic soil. The presence of organic content in the soil has detrimental impacts on the physical and strength behavior of soil. To investigate the effectiveness of fly ash in the stabilization of organic soil, two types of fly ashes (Type I and Type II) at different...

In this study, the elevated temperature flexural strengths of lightweight foamed concrete (LFC) containing fly ash (FA) and polypropylene fiber (PF) was investigated experimentally and statistically. The variables included were the temperature degrees (in a range of 20 to 600°C), LFC densities of 600, 800, 1000, 1200 and 1400 kg/m3 and additive content. Two mixes were made by replacing 15% and ...
متن کاملBiofunctional Characteristics of Lignite Fly Ash Modified by Humates: A New Soil Conditioner
Fly ash superficially modified with humic substances from the Megalopolis lignitic power plant was prepared and evaluated for agricultural uses. UV-vis spectrophotometry and IR spectroscopy revealed that fly ash shows high sorption efficiency towards humic substances. Adsorption proceeds stepwise via strong Coulombic and hydrophophic forces of attraction between guest and host materials. Langmu...
