The aggregate comprising the test sample must be dried and cooled in an oven for four hours at a temperature of 100 to 110°C. Fill the measure roughly one-third full with aggregate and tamp with 25 strokes of the rounded end of the tamping rod. Repeat the process with two additional layers until the cylinder is filled.

The maximum aggregate size is 120 mm, and the four aggregate grades studied were 5–20 mm, 20–40 mm, 40–80 mm and 80–120 mm. Table 3 lists the RCC mixtures. All the tests and sample sizes met the DL/T5433-2009 standard. All the samples were in the same shape and size. Table 4 lists the concrete sizes of each kind of …

The procedure of the impact value test includes the following series of steps: 1. The aggregate samples of size 10mm to 12.5mm (passing through 12.5mm sieve and retained on 10mm sieve) are first taken and oven-dried at a temperature ranging from 100 degrees Celsius to 110 degrees Celsius for about four hours. 2.
