“…An experimental study has shown that increase in compactive efforts lead to an increase in MDD and simultaneous decrease in OMC [25]. It has been concluded that the cement stabilized and fiber reinforced clay mixed with optimum percentage of rice husk ash and pond ash can be an effectively used as geotechnical fill materials [26]. Improvement in strength and durability characteristics has been observed using lime in class F fly ash [23].…”

“…But further improvement in the strength of soil-pond ash mix can be achieved using some additional treatment. For instance, the combined effect of pond ash, fibers and cement can further improve the strength of soil [26,28]. But the combined effect of pond ash and fibers on the properties of soil is yet required further to be studied.…”

This paper presents the experimental results obtained from tests conducted on clayey soil specimen stabilized with pond ash (PA) and cement and reinforced with randomly distributed fibers. The amount of PA and cement were varied from 0-50 and 0-6 % respectively by dry weight of the soil. In order to understand the influence of admixture on the strength properties of clay, compaction tests, unconfined compression tests (UCS), split tensile strength (STS) tests and California bearing ratio tests (CBR) were conducted. In addition scanning electron microscopy and X-ray diffraction tests were carried out on certain samples in order to study the surface morphological characteristics and hydraulic compounds, which were formed. The specimens were tested for their strength behaviour at different curing periods. The obtained results have shown that addition of mixtures leads to a decrease in the maximum dry density and increase in optimum moisture content. The results also indicate that the proposed method is very effective to improve the strength of the clayey soil in terms of UCS, STS and CBR tests.

“…Most of the experimental research presented so far regarding the mechanical behaviour of fibre-reinforced cemented sands entails the analysis of these composites under compression or split tensile loading [2,5,6,7,8]. The mechanical behaviour of fibre-reinforced cemented sands under flexural tensile loading (where failure occurs only due to tensile stress) has not been studied as extensively [9,10].…”

Behaviour of fibre-reinforced cemented sand under flexural tensile stress

In soil improvement, the insertion of cement to the soil matrix provides an increase in strength and rigidity of the material, whereas fibre addition provides an increase in ductility, reducing post-peak loss in strength. This research aims to experimentally analyse the mechanical behaviour of unreinforced and fibre-reinforced cemented sands under flexural tensile monotonic loading conditions. In order to do so, an experimental program was planned using silty sand (Arenito Botucatu), early strength Portland cement -CPIII, and polypropylene fibres 24 mm long and 0.023 mm thick. Three different dry unit weights (d) (18, 19 and 19.7 kN/m 3 ), three cement contents (3, 5 and 7%), and two fibre contents (0 and 0.5%) were chosen. Analysing the results, an increase in cement content generates an increase in flexural strength (qf) for all concentrations and the increase in d generated smaller qf gains, especially for lower cement contents. The addition of fibres generated a qf increase for lower d but at higher d there was a reduction in the influence of fibre addition on strength gain. The reduction can be attributed to an entanglement of the fibres in higher compaction strengths, disrupting the formation of cementitious bonds. However, based on a qualitative assessment, there was a noticeable reduction in post-peak strength loss due to fibre insertion. The parameter porosity/volumetric cement content (/Civ 0.28 ) was considered suitable to predict the qf mechanical behaviour of the studied composite.
