about 3/8 to …Efflorescence is the white powdery substance on the surfaces of unsealed concrete and the white blush seen with sealed floors. Efflorescence is caused by vapor migrating through the slab bringing soluble salts to the surface of the concrete. Efflorescence is normally worn off or washed away on unsealed concrete surfaces.Calculation of volume of aggregate in 1m^3 of concrete. Volume of aggregate = Ratio of aggregate / (Cement+Sand+Aggregate) x 1.57. = 3 / 5.5 x 1.57. = 0.86 m ^3. Now
