Explain what compaction is
WebDynamic compaction (DDC, heavy tamping, dynamic consolidation, etc.) is a cost-effective method of soil compaction whereby a heavy weight is repeatedly lifted and dropped from a height, impacting the ground surface with a readily calculated impact energy (Figures 6.12 and 6.13).Costs are reportedly about 2/3 that of stone columns, with up to 50% savings … WebPerson as author : Pontier, L.

WebCompaction is the artificial and mechanical process of decreasing the volume of the soil rapidly by the expulsion of air voids in the soil resulting in the increase in density. Densification of soil also occurs naturally due to consolidation of foundation soils by expulsion of pore water due to loads from the structure. WebThe procedure of the Proctor Compaction Test consists of the following steps: Obtain about 3 kg of soil. Pass the soil through the No. 4 sieve. Weight the soil mass and the mold without the collar (W m ). Place the …

Sieve it through 20mm and 4.7mm sieve. Calculate the percentage retained on 20mm sieve and 4.75mm sieve, and the percentage passing 4.75mm sieve. If the percentage retained on 4.75mm sieve is greater than 20, use the large mould of 150mm diameter.
