Each year, Vietnam gains a million inhabitants. There are many people who want housing, transport and energy. In parallel, the country's authorities want to invest in housing and infrastructure that will support the development of the country, which has seen annual growth of 5% for the past 20 years.
The problem is that, as a strip of land along the South China Sea, Vietnam is cut through with numerous rivers and deltas. As a result, the ground is often loose and unstable, making constructions fragile. This has given rise to many difficulties.
But taking an antiseismic technique invented in Japan as a starting-point, our subsidiary in Vietnam has found a solution: Soilcrete, a cement incorporating 60% slag (steel mill waste with the properties of a hydraulic binder), is injected directly into the soil to ensure stability. Capable of reducing cracking in massive structures, it is now being used in a series of major infrastructure projects and in housing developments.
Tomorrow, it could even be used in the manufacture of special concrete with resistance to seawater and low temperatures. And why not in the residential sector? An ideal solution that will help meet the needs of the population of a fast-growing country!
