Durability and microstructural behavior of Nano silica-marble dust concrete
Present study assesses the durability performance of concrete mix with the addition of marble dust and Nano silica as partial replacement of cement.Concrete blends with 1 %, 2 %, and 3 % Nano silica and 5 %, 10 %, and 15 % marble dust powder were prepared at constant water to binder ratio of 0.4.The bulk density, water permeability, water absorptio
