What does CDM mean in ACADEMIC & SCIENCE

Cement Deep Mixing (CDM) is a construction method that uses a cement-bentonite slurry to create strong and stable deep foundations. The slurry is pumped into boreholes drilled in the soil and forms columns when they harden. These columns help improve the stability and strength of the foundation.

In the CDM process, boreholes are first drilled into the ground and then filled with water-cement-bentonite slurry. The slurry is pumped into the holes and allowed to harden which creates dense cemented columns beneath the surface of the soil. Once hardened, these columns help improve stability and strength of structures built on top or in close proximity of them.

CDM can be used for a variety of projects including bridge abutments, remediation barrier walls for contaminated sites, earthworks for roads or embankments, and much more. It provides improved safety and stability compared to other construction methods due to its ability to construct deep foundations that remain strong over time even under large loads or high water pressures.

The main advantage of using CDM is its ability to construct deep foundations quickly with minimum disturbance to nearby structures or buildings. It also requires less labor compared to traditional construction methods since it only requires drilling holes into the ground and filling them with slurry instead of excavating large amounts of soil during installation. Other advantages include improved safety due to stronger foundations, better overall performance through increased stability at deeper depths than traditional methods can provide, less material consumption due to quickly setting up materials such as reinforced concrete piles or H beams after installation, and cost efficiency due to its quick setup time resulting in lower labor costs associated with traditional methods of construction.
