Abstract

In the present work suitability of diatomaceous earth asa partial replacement to cement in the concrete is studied by analysing strength and durability properties.Cementpartially replaced with diatomaceous earth (DE) in incremental proportions of 0%, 5%, 10%, 15%, 20% and 25%and the mechanical properties like compressive strength for 7 and 28 days and spilt tensile strength studied. Concrete with 15%DE shows maximum compressive strength compared with reference mix and microstructural analysis of concrete by conducting SEM, SEM WITH EDS and XRD ascertain the same.
