    The Effect of Aggregate Properties on Concrete

    Lightweight concrete contains aggregate that is natural or synthetic which weighs less than 1100 kgm 3 and heavyweight concrete contains aggregates that are natural or synthetic which weigh more than 2080 kgm 3. Although aggregates are most commonly known to be inert filler in concrete the different properties of aggregate have a large.
