STUDY ON STABILIZATION OF DREDGING MATERIAL IN LACH HUYEN NAVIGATIONAL CHANNEL FOR CONSTRUCTION MATERIAL

Abstract

In this paper, the author analyzes the particle size composition of the dredged material of Lach Huyen channel in Hai Phong, and carries out the experiments, assesses, and selects suitable chemical additives to stabilized this dredged material for reusing it as construction materials. The author has conducted experiments in the field with the 50m² of the cargo yard, through the model, the mechanical properties of the field drilling samples have been evaluated and compared with the technical requirements in TCVN 10379: 2014.

According to preliminary estimation, if this technology is used to build warehouse and road foundation, it will save about 30% of the cost compared to the traditional construction methods, and contribute to ensuring the ecological sea environment.
