Preliminary Investigations for Policy Framework to Regulate the Utilisation of Residual Strength of Demolition Waste Aggregate in Cement Concrete Mix

M. R. Raja Shekhara, Reshma. E. K.


Millions of tonnes of demolition waste of different types is generated from various sources in the construction industry. Improper disposal of such waste results in loss of valuable land in cities and also such deposits may breach into reservoirs, water bodies, canals, etc. leading to blocking the path for the free flow of rainwater. Dissolution of harmful compounds that may be present results in contamination of water bodies. Hence it is necessary to frame guidelines and rules for regulating the various Demolition activities. This facilitates the granting of permission, actual demolition, segregating different materials and making the best use of the derived aggregates for various activities. Using derived aggregates in partial /full replacement is possible in concrete mixes of different grades. An attempt is made to collect demolition waste from three different locations. Requisite tests were conducted. An attempt is made to design a pavement quality concrete (PQC) of M40 grade to satisfy compressive and flexural strength requirements. A policy framework is needed at the national level for utilizing demolition waste aggregate in civil engineering works of both structural and nonstructural applications. Proper regulation of CD waste management is essential to channelize the entire process to convert it into useful construction material.
