Properties Of Soil

The soil must be able to withstand the load and transfer it to ground within the range of allowable deformations, for which it must possess good physical and geotechnical properties. The conventional method of stabilization such as removal and replacement of ill – suited soils incur higher cost and is time consuming. A new method of stabilization, designated as chemical stabilization can be adopted. This method initiate chemical reactions such as cation exchange, pozzolanic activity etc., which consequently enhance the geotechnical properties of soil. In this study, the mechanical behavior of soil is improved by addition of nanoparticles i.e., nano silica along with cementitious material, lime. Considering economic issues of nano silica usage and results of this research in soil stabilization projects, in this study 0, 1, 3 and 5 % weight of nano silica is used as well as 0, 2 and 4 % weight of lime is used. The effect of these replacements is studied by Atterberg limits test, compaction test and unconfined compressive strength (UCS) test. The effect of curing time on samples at 3, 7 and 28 days of age has also been investigated. The optimum percentage replacement of nano silica in lime stabilized soil is determined. The microstructure of the stabilized soil is studied by Scanning electron microscopy (SEM) test. Thus the results proved that there is a significant improvement in the plasticity, compaction and strength properties with slight addition of nano silica in clayey soil mixed with lime.

Precise determination of engineering properties of soil is essential for proper design and successful construction of any structure. The conventional methods for determination of engineering properties are invasive, costly and time-consuming. Electrical resistivity survey is an attractive tool for delineating subsurface properties without soil disturbance. Reliable correlations between electrical resistivity and other soil properties will enable us to characterize the subsurface soil without borehole sampling. This paper presents the preliminary results of an ongoing research on correlations of electrical resistivity with strength properties of soil. Soil investigations, field electrical resistivity survey (VES) and laboratory electrical resistivity measurements were conducted. From the data analysis, significant correlations have been obtained between resistivity and moisture content and angle of internal friction. Weaker correlations have been observed for cohesion and unit weight of soil.

Earth represents an ecological building material that is thought to reduce the carbon footprint at a point in its life cycle. However, it is very important to eliminate the undesirable properties of soil in an environmentally friendly way. Cement-stabilized rammed earth, as a building material, has gradually gained popularity due to its higher and faster strength gain, durability, and availability with a low percentage of cement. This paper covers a detailed study of hollow compressed cement-stabilized earth-block masonry prisms to establish the strength properties of hollow compressed cement-stabilized earth-block masonry. The test results for masonry prisms constructed with hollow compressed cement-stabilized blocks with two different strength grades and two earth mortars with different strengths are discussed.

Properties Of Soil

One of the main objectives of crop establishment is adjustment of physical properties of soil, on which indicators of soil fertility as well as economic appreciation of the resulting yield depend. During 2014–2016 yield of corn and sorghum was observed in semi‑operational experiments of ZD Budišov in relation to the quantity of the applied digestate and simultaneously, the following physical properties of soil were analysed: porosity, compaction and soil structure. After the application of digestate the porosity and minimal air capacity decreased, and reduced bulk density increased. Soil structure was affected negatively too. Overall, a trend of degradation of physical state of soil in variant with doubled dose of applied digestate was registered. Yields were always higher in variants with digestate due to a higher supply of higher amount of nutrients. Results of this observation indicate that crop yields may be higher but at the same time physical properties of soil may be impaired which may, while increasing doses of digestate, lead to irreversible degradation of soil.

Properties Of Soil

Soil stabilization known as the process of improving the engineering properties of soils is a method applied when the engineering properties of soil are not suitable for purpose. There are several methods of soil stabilization that could be implemented to improve the physical characteristics of the soil. In this study, the pine tree sawdust as an organic material wase used as additive material for stabilization of clayey soils and the influence of pine tree sawdust on the geotechnical properties of clayey soil was investigated in terms of strength behaviors. The pine tree sawdust is an organic waste resulting from the mechanical milling or processing of timber (wood) into various standard shapes and useable sizes. The strength properties of the clayey soil when blended with pine tree sawdust indicates that the pine tree sawdust is a good stabilization material for this problematic soil. As a result, it is concluded that the pine tree sawdust material as an organic material can be successfully used for the reinforce of clayey soils in the geotechnical applications.

This work studies the possibility to produce the new novel brick by mixing between the local soil, local lime and burnt hull ash which is the waste in the earthenware industry. All materials conducted in this work are found in Ratchaburi province located in the western of Thailand. The chemical and mechanical properties are studied including the thermal conductivity will be determined. Varying burnt hull ash (BHA) contents are added into the combination and compared properties with the soil cement brick (RCB) at the same percentage weight. Results show that the compressive strength and flexural strength of soil brick mixed with 10% constant lime and varying burnt hull ash contents (CLBA) shows the maximum values at BHA of 25% by weight at water to powder ratio of 0.4225 and the thermal conductivity of CLBA is lower than that of SCB given as 43.98%.
