EFFECT OF LIQUID POLYMER STABILIZER ON GEOTECHNICAL PROPERTIES OF FINE GRAINED SOILPant, Ashish Dev 01 May 2016 (has links)
Soil stabilization is a common technique to increase the strength and durability and also to reduce the swell-shrink behavior of foundation soil or subgrade soil in pavement. Nowadays, several nontraditional stabilizers (e.g., Polymer, Enzyme, Ionic stabilizer etc.) are available in market whose behavior is not fully understood for wide range of soil types. In the present study two types of soils i.e., Carbondale soil ‘clay with high plasticity (CH)’ and Galatia soil ‘silt with low plasticity (ML)’ has been used. A commercially available liquid polymer “Soiltac” was selected as a stabilizer and mixed with both the soils at various percentages i.e., 0.0%, 0.5%, 1.0%, 1.5% and 3.0% by dry weight of soil to study the effect of polymer on geotechnical properties of soil. Particle size distribution, liquid limit, plastic limit, specific gravity and standard Proctor tests were conducted to identify the basic index properties of the soil. Unconfined Compressive Strength (UCS) tests were conducted after 3 days, 7 days and 28 days of curing period for CH soil. For ML soil, UCS tests were carried out after 7 days and 28 days of curing period. In addition, California Bearing Ratio (CBR) tests were conducted for CH soil at unsoaked and soaked (soaked for 96 hours) conditions. With the addition of stabilizer, no significant changes in UCS values were obtained for ML soil. For CH soil, UCS values increases upto 1.5% stabilizer dose and then decreases with 3.0% of stabilizer. Also, for CH soil, UCS value increases with the increase in curing period. For CH soil, the unsoaked CBR value increases upto 1.5% stabilizer dose and then decreases with 3.0% of stabilizer but no significant improvement in soaked CBR values were found.

The effect of silt-laden water on infiltration in alluvial channelsMatlock, William Gerald,1929- January 1965 (has links)
A tilting bed flume study was made to examine the relationships between velocity, suspended sediment and infiltration rate in alluvial channels for velocities from 2 to 5 feet per second and suspended sediment up to 0.6 percent. Preliminary experiments using samples from Rhllito Creek near Tucson, Arizona to define limits for the flume study included mechanical analyses of bed sediments, permeability and infiltration tests, and analyses of suspended sediment in flood waters. Flume experiments using bed materials from Rillito Creek were made with constant velocity and variable suspended sediment content, then with constant suspended sediment and variable velocity. Considerable variability was found in the mechanical analyses, permeability and infiltration tests, and suspended sediment content for samples from different locations. The flume studies indicated a direct relationship between velocity and infiltration rate and an inverse relationship between the suspended sediment content and infiltration rate in the ranges tested. Very poor correlation was found between the preliminary permeability and infiltration tests and the flume infiltration rates, but good correlation was obtained for the flume results with the flow losses and natural recharge occurring in the river channels in the Tucson area.
