Improvement of mechanical parameters of concrete yielded from pozzolanic cement for irrigation and drainage projects

Among various active parts of construction industry, irrigation and drainage projects (such as dams, spillways and peripheral parts such as canals) are one of the biggest consumers of cement. Various empirical reports show that the concrete made of Ardabil’s pozzolanic cement does not meet the requi...
