CONTROLLED LOW STRENGTH MATERIALS (CLSM) AS BEDDING LAYER - AN EXPERLMENTAL STUDY AND NUMENICAL EVALUATION
摘要
The utilization of coal ashes to replace different natural aggregates is a standard procedure adopted nowadays for different civil engineering applications. Reutilization of these industrial waste products generated from the thermal power plants for civil engineering applications is beneficial to society and the environment in various ways. Thus, this research paper deals with the studies done to analyse the effectiveness of using pond ash for controlled low strength materials (CLSM) production. Further, stresses and strains developed on the buried pipelines where CLSM was used instead of the standard aggregate-based bedding layer were also analysed. A comparative study of the stresses and strains developed on the buried pipelines was evaluated using PLAXIS 2D software. The results from the studies showed that the plastic and in-service properties obtained for the pond ash-based CLSM mixtures are equivalent to regular aggregates used in bedding layer applications. Further, the analysis of stresses and strains developed on the buried pipelines using the Plaxis 2D numerical tool showed that the stresses and strains developed on CLSM as bedding layer-based pipelines performed better than the normal bedding layers. Thus, pond ash-based CLSM mixtures can be used as an alternative to normal aggregates as the stresses and strains developed were found to be lesser than that of normal aggregate-based bedding layers.
