Durability Of Manufactured Sand

Nowadays, Manufactured Sand has been incorporated in concrete mix design by replacing sand in fixed proportions or completely for economic considerations. Latest studies have been conducted considering the possibility of using Manufactured Sand as a complete replacement of sand without impairing the strength and its durability

    Manufactured Sand (M-Sand) produced by the crushing of hard granite has been identified as a good substitute for natural sand. The main objective of this study is to check the strength and durability characteristics of HPC using M-Sand along with 5% silica fume. The natural sand was replaced by M-Sand on proportion of 0%, 20%, 40%, 60%, 80% and

    Nov 23, 2018 The natural sand which excavated from river bed is used to produced conventional concrete. Depletion of natural sand cause the environmental problem and hence sand excavating is restricted by government which resulted in shortage and drastically increase in its cost. In order to fulfil the necessity of fine aggregates, an alternative material like M sand can be used in concrete. M sand

    Nov 11, 2018 An appropriate amount of stone powder improves the durability of manufactured sand concrete. When the stone powder content is 10% or more, the chloride diffusion coefficient of manufactured sand concrete is lower than that of natural sand, and its permeability is better than that of natural sand. In a certain range, the slump and diffusion coefficient of concrete show the same trend
