    Effects Of Crushed Stone Dust On Some Properties Of Concrete

    Abstract crusher dust is a fine material formed during the process of comminution of rock into crushed stone or crushed sand this dust is composed by particles which pass 75 μm bs sieve effects of dust content in aggregate on properties of fresh and hardened concrete are not known very well an experimental study was undertaken to find out the effects of various proportions of dust content on properties of fresh concrete and hardened
