Use of Basalt Fibers for Soil Improvement

Abstract

Soil reinforcement with natural and man-made fibers is one of the techniques to improve a number of mechanical and physical properties of soils. Although basalt originated fibers are currently being used for concrete, it is not an easy task to find a source in literature concerning the use of basalt fibers for soil improvement. In this study, basalt fibers have been used for this new aim. This study is an investigation into evaluation of the increase in soil strength, which is reinforced, in different percentages, by basalt chopped fibers. A silty soil sample has been chosen for this study and has been mixed, with 6, 12, and 24 mm long basalt fiber at varying contents. The unconsolidated undrained triaxial tests show that the addition of 24 mm long fibers into soil gives the maximum improvement in strength and the optimum fiber content (by dry weight of soil) is 1.5%.

Comparison of Mechanical Properties of Unidirectional and Woven Carbon, Glass and Aramid Fiber Reinforced Epoxy Composites

“…Mechanical properties of fiber reinforced composites in these studies are investigated experimentally, numerically and analytically [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. There are also some studies on basalt fiber and hydrojel composites [19,20] Frangopol et al investigated the reliability of a composite laminate plate by using Tsai-Wu failure criterion. Fiber orientation, layer thickness and number have a significant effect on the reliability of fiber reinforced composite plates [3].…”

Evaluation of Marble Dust for Soil Stabilization

“…Recently, different additive materials such as fly ash, rice husk ash, silica fume, ladle furnace slag and geo fibers are used to improve some geotechnical properties of poor soils [4][5][6][7][8][9][10]. Besides these additives, industrial wastes such as olive oil wastes [11] and basalt fibers [12] are also used for remediation of soils. Yilmaz et al [13] have used stone wastes in stabilization of clayey soils as a pozzolanic additive.…”

Enhancing the Engineering Properties of Indian Black Cotton Soil with Municipal Solid Waste Incineration Ash – A Review

“…The addition of CCR to soil showed an increase in OMC, UCS and CBR values and decrease in specific gravity, plastic limit and MDD and the optimum content of CCR was noted as 4% [15]. Soil Stabilization through the addition of different fibres, cement and sand has been studied by number of researchers [16][17][18][19][20][21][22][23]. The addition of these fibres in proper proportion brings significant improvement in engineering properties of weak soils.…”
