Compaction characteristics of fine grained soil and rice husk ash mixture

Abstract

This study presents the compaction characteristics of fine grained soil and rice husk ash (RHA) mixture. Three types of fine grained soils viz., montmorillonite clay, kaolinite clay, and one local soil has been used in the present study. From the compaction tests results it is observed that with increase in RHA content (0-30%) maximum dry density (MDD) decreases and also optimum moisture content (OMC) increases irrespective of types of fine grained soil. Based on the experimental data, a number of linear regression models have been developed to estimate MDD and also OMC of fine grained soil and RHA mixture. Empirical models also presented to estimate dry density in terms of water content of dry side of optimum or water content of wet side of optimum, compaction energy, RHA content, and also specific gravity of fine grained soil and RHA mixture. The above models may be useful for the field engineers within the range of compaction energy from 300 kJ m 23 to 2700 kJ m 23 , RHA content from 0%-30%, specific gravity of fine grained soil and RHA mixture from 2?311-2?750, and OMC for soil from 16?8%-37?0%.

Influence of Fly Ash Content on Compaction Characteristics of Fly Ash Clay Mixture

“…In series A, compaction tests have been performed with varying compaction energies in a wide range (2700 kJ/m 3 , 594 kJ/m 3 and 300 kJ/m 3 ) and varying fly ash content (0%, 5%, 10%, 15%, 20% and 25%) to study the effect of compaction energy and fly ash content on fly ash clay mixture. A number of researchers (Daniel and Benson, 1990;Boltz et al, 1998;Bera et al, 2007;Bera and Ghosh, 2011;Bera, 2014) considered all three types of laboratory compaction tests; i.e., modified proctor test, standard proctor test and reduced proctor test in their studies. In series B, standard proctor compaction test has been performed on three types of clay with fly ash content (0-25%) for two types of fly ash (BTPS and BBTPS).…”

“…Detailed study on compaction characteristics of pond ash has been performed by Bera et al (2007). Bera (2014) studied the compaction characteristics of fine grained soil rice husk mixture. However, detailed study on compaction characteristics of fly ash clay mixture is scarce.…”

The Combined Effect of Pond Ash with Borrowed Soil Materials Along with Milling Waste for Flexible Pavement Sub-Grade Crater Foiling and Strength Characteristic Enhancement

“…The importance of the study of waste treatment plants concerned with soil pollution and the harmful effects on the environment effects is essentially monitored periodically to ensure the different types of soil characteristics and their strengths are studied thoroughly by qualified and essential team members during the experimentation process (Sharma and Sharma, 2021). The latest software was employed to get adequate results and past results of the soil permeability and its corrosion resistances throughout the concrete materials; flitched materials concerning the different densities ranging from 10 g/m 3 to 100 kg/m 3 are ensured with the help of OSTU technology followed by (Gupta et al, 2020), According to the (Arun et al, 2017), the gradual failures in the soil were found in the order of 5 to 10% compared to last two years; due to the lack of awareness of strengthen characteristics of the lake soil compared to the industry soil; the fragmented release of these minute diffractions defects the entire construction buildings resulting in the high maintenance costs compared to brick concentrates. Hence, it is required to study the properties of the soil, followed by erosion testing, corrosion testing, absorption tests, and diffraction stages.…”

Influence of Compaction Energy on Cement Stabilized Soil for Road Construction

“…For both treated and untreated soil compaction, compaction energy is a critical element. High compaction energy applied to the soil produces more densification, and thus a higher maximum dry density [1]. Many scientists have investigated compaction energy's impact on the engineering characteristics of both unstabilized and stabilized soils.…”

“…Variations of MDD, OMC, CBR SP, and PS resulting from the compactive efforts raising and quarry dust percentage are statistically significant at a 5% level. Bera (2014) [1] presented the compaction parameter variations of grained soil (fine) treated by rice husk ash. Based on the findings, he created linear regression analyses to estimate the density and moisture content of the soil-RHA mixture and drew the following conclusions: (1) the density of soil reduces when the addition proportion increases.…”
