  • Slump Test of Concrete, slump cone for Workability - Procedure, Apparatus - Cement Concrete

    23/4/2020 · Much research shows that for the "very high" category of workability, the flow test is more suitable for workability measurement. For large construction projects, a slump test is a very useful tool to check day-to-day or hour-to-hour variation of the quality of the concrete mix, and by observing slump reading, we can easily change the moisture (water) content and grading of concrete.

  • Experimental Research on Durability of Fly Ash Pavement …

    1/3/2013 · The durability of RAC, cast with the same water/cement ratio, is lower than that of the conventional concrete due to the higher porosity of recycled aggregates. However, in low water/cement ratio concretes, the low porosity of the new paste is predominant so the advance of aggressive agents is delayed, obtaining a similar behaviour for the control and recycled concretes.
