Silica fume concrete after 155 months
Research output: Contribution to journal › Article
Long-term experimental studies on the interaction between silica fume and Portland cement in concrete subjected to air, water or sealed curing, are outlined. For this purpose 6000 kg of eight qualities of concrete were studied at 5 ages over a period of 155 months. Half of the concrete contained silica fume. Parallel studies of strength, hydration and rela-tive humidity were carried out. After 155-month tests were also per-formed on the salt freezing and thawing frost resistance of the concrete. The results show a great effect of silica fume on compressive and split-ting tensile strength, hydration, relative humidity in low-water-cement ratio concrete and on salt-thaw frost resistance of silica fume compared to the effect of Portland cement. The work was performed 1989 - 2003.
