Barite

 

In the coming time Vietnam is going to set up an atomic energy power plant( in the second decade of 21st century). To get sufficient material supply free from radioactive to build the plant the authors have conducted applicative experiments on some raw mineral materials available in Vietnam: barite of Phu Tho, serpentines of Thanh Hoa as aggregates to produce special concrete. All the experiments have been conducted using Vietnamese standard in laboratory for concretes and building materials of the Research Institute of Construction and Technology, Ministry of Construction. As a result obtained, 2 samples of barite and one samples Qf serpentines concrete are chracterized by some physical parameters e.g. barite concrete: density 3.2 - 3.6, compressive strength after 28 days = 285-332 daN/cm2, serpentines concrete: Density: 2.56, compressive strength 227 daN/cm2.
