【 摘 要 】

In recent times, the interest of scientists in new additives has increased, which can be modified by the properties of concrete mixtures and the parameters of hardened concrete. The PN-EN 197-1:2002 standard permits the use of mineral additives for cement, both as a main component (> 5.0% by weight) and as a secondary component (
