    Analysis of Strength Properties of Cement-Stabilized Soil at Different Moulding Water Contents
    (Springer Science and Business Media Deutschland GmbH, 2021) Bariker, P.; Kori, A.; Hulagabali, A.M.
    In the present study, an attempt is made to evaluate the strength properties of red soil mixed with ordinary Portland cement. A series of standard proctor Tests, unconfined compression strength tests, direct shear tests and split tensile strength tests were performed on samples of red soil with a mixture of 6, 9 and 12% at an increment of 3% of ordinary Portland cement. The tests were conducted on red soils with specific gravity of 2.59 subjecting those to above-specified tests as per Indian Standards IS: 2720. At each mixture of each percentage of ordinary Portland cement sand, peak frictional angle and soil cohesion were found out by conducting direct shear tests. Most of the direct shear tests were conducted to shear strain in excess of 30%, and the stress–strain response was observed and recorded. Also in the present work, the comparison in strength properties was done between the soils at wet of optimum and dry of optimum for all above-mentioned tests. The present trend of results was also matched with those of previous works. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

    Improvement in the Properties of Red Soil Using Granulated Blast Furnace Slag
    (Springer Science and Business Media Deutschland GmbH, 2022) Preetham, H.K.; Nayak, S.; Jagapur, P.
    In the current study, an attempt is made to improve the geotechnical properties of red soil using industrial by-product: Granulated-Blast Furnace Slag (GBFS). Red soil is distributed over large part of the peninsular region in India. Red soil could be effectively stabilized to yield better strength characteristics. GBFS is the primary by-product of the iron and steel industry. Red soil was replaced with varying percentages of admixture (GBFS) by dry weight of soil (5, 10, 15, 20 and 30%). Basic geotechnical properties like specific gravity, Atterberg limits, compaction, unconfined compressive strength (UCS) and triaxial compression test, were performed on the red soil as well as on the mixes as per Indian Standard Codal provisions. From the UCS test results, the optimum percentage of replacement of 15% was found. It was observed that on replacement with admixtures, the liquid limit was found to decrease which reduces the compressibility. The presence of CaO in GBFS has improved the shear strength and shear strength parameters of soil. Thus utilization of granular industrial by-product (GBFS) has proven beneficial in geotechnical structures. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
