Abstract

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.
掺入凝灰岩和灰岩的混凝土透气性分析
摘要本研究旨在分析以凝灰岩和灰岩作为补强火山灰材料对经典C12/15混凝土组合物渗透性的影响。设计了两种不同渗透程度的混凝土组合,P810和P1210作为参考混凝土组合,凝灰岩水泥掺量分别为6%和10%,石灰石掺量相同的8种试验混凝土组合。结果表明,凝灰岩和灰岩的掺入会降低混凝土的渗透性,其中凝灰岩掺入量为10%时,混凝土的渗透性为P810级。
