Investigational Study on the Influence of Marble Dust and Silica Fume in the Stabilization of Clayey Soil
Ankush Sharma [2] | Anoop Sharma
Abstract: Marble dust and silica fume are waste materials which are being discarded every year in India in substatntive quantity into the environment. Marble dust powder is obtained as a waste product from the marble industry.Silica fume is the by-product of silicon and ferrosilicon alloy. In this study, an experimental program to study the effect of the combination of silica fume and marble dust powder on clayey soil using Indian standard light compaction test, unconfined compression strength test, and direct shear test has been undertaken. In this experimental study different ratios and different proportions have been used to find the effect of silica fume and marble dust with clayey soil. The tests that were conducted include unconfined compressive strength test, standard proctor test, direct shear test and Atterberg limits.. With marble dust kept constant at 18% MDD decreases with an addition of silica fume in clayey soil and marble dust mix.The UCS value increases from 0.934 kg/cm? to 2.838 kg/cm? with the addition of marble dust and silica fume. Based on the direct shear test results, the value of cohesion increases from 0.280Kg/cm2 to 0.512Kg/cm2 and angle of internal friction increases from 24.10 to 30.57. The results showed that silica fume and marble dust powder could improve the UCS, cohesion and angle of internal friction of clayey soil sample. Hence, the addition of silica fume and marble dust powder makes the soil mixes durable, economical and effective for soil stabilization.
