    HOMOGENEITY OF CONCRETE: It is quite obvious that concrete ingredients if batched and mixed properly give a homogeneous mix which is essential so that the properties of concrete are uniform. A non-homogeneously mixed concrete can result in large strength variations, shrinkage, bleeding, segregation and various other defects, which will result in poor quality of concrete or mortar.
