CAPILLARY RISE CHARACTERISTICS AND SALTWATER PROPAGATION IN FINE AGGREGATE: TOWARD DEVELOPING THE ANTI-SALINITY SHALLOW FOUNDATION
Assoc. Prof. Dr. Nguyen Ngoc Truc, Msc. Nguyen Van Hoang, Msc. Tran Ngoc Tu
This study is carried out to determine the capillary rise over time of fine aggregate in different saline media. The obtained results showed that the capillary height in fine aggregate is inversely proportional to the salt concentration of the capillary solution. The aggregate that has a particle size over 2.0 mm shows the best ability to limit capillary rise. The capillary height of the aggregate gets the highest value when there is no salt in the solution and gets the lowest one with the solution at the highest salinity tested, i.e. 33.0 g/L. The obtained results on capillary characteristics lead to an idea of design a shallow foundation that has a function of anti-corrosion, anti-salinity proactively and effectively.
