09:58' SA-03, 03/01/2014

Construction laboratory of HEC was granted with LAS-XD119 by the Ministry of Construction. HEC’s laboratory has undertaken testing for almost of large hydraulic and hydropower projects, transportation, civil and industrial construction projects of Vietnam and projects with foreign investment capital.

Professional capability:

• Field and laboratory testing on mechanical and physical characteristics of soil;
• Testing soil, rock on structure foundation;
• Testing chemical characteristic of water;
• Testing mechanical and physical characteristics of construction materials (cement, crushed stone, steel, etc.);
• Testing for analysis of environment factors (water, waste, air, etc.);
• Testing of mechanical and physical characteristics of concrete, concrete mixture, rolled compacted concrete;
• Determination of mechanical characteristic of structural material.
• CPT testing, checking density, VST.
