Abstract

This research aimed to analyze the effects of using tuff and limestone as supplementary pozzolanic materials on the permeability of a classic C12/15 concrete composition. There were designed two types of concrete compositions with different degrees of permeability, namely P₈¹⁰ and P₁₂¹⁰ as reference concrete compositions and eight experimental concrete compositions with tuff in 6% and 10% of the cement quantity and with limestone in the same proportions. According to results, the tuff and limestone led to the decrease of concrete permeability, the best values being registered in the case of using 10% tuff in the concrete composition with P₈¹⁰ class of permeability.
