Inspection and testing of ready mix concrete is crucial to ensure that all specified conditions meet the acceptable criteria. Ready mix concrete, which produced in batching plant and transported to construction site by truck mounted mixers, are commonly inspected and tested in accordance with applicable standards such as ASTM international. 1.
18/3/2017 · It is important to compact the concrete fully because: Air voids reduce the strength of the concrete. For every 1% of entrapped air, the strength falls by somewhere between 5 and 7%. This means that concrete containing a mere 5% air voids due to incomplete compaction can lose as much as one third of its strength.
