With a workable concrete mix, slump test and making concrete cubes was also done. Slump test When making the slump test, the base of the slump cone was put on a flat surface. The cone was then filled with wet concrete in three layers. Each layer was tempered 25 times with a standard 16mm (diameter steel rod, rounded at the end).

The following are some of the important tests conducted on concrete: 1. Slump test. 2. Compaction factor test. 3. Crushing strength test. Slump Test This test is conducted to determine the workability of concrete. It needs a slump cone for test (Fig. 3.3). Slump cone is a vessel in the shape…

Jan 30, 2018· A single-particle crushing test was carried out for more than 170 recycled aggregates from waste concrete. Recycled aggregates were sieved into 30- and 40-mm particle size groups, mainly consisting of mortar with 2–10 natural aggregates. At the initial loading of the single aggregate, its irregular surface was close to the loading plate ...
