Classification of Aggregates
The most common classification of aggregates on the basis of bulk specific gravity is lightweight normal weight and heavyweight aggregates This section As mentioned in the body of this paper lightweight concrete contains aggregate that is natural or synthetic which weighs less than 1100 kg m3 The lightweight is due nbsp
