Ak. Chakraborty et Sc. Dutta, Study on silica fume modified mortar with various Indian cements cured at different temperatures, BLDG ENVIR, 36(3), 2001, pp. 375-382
The compressive strength of silica fume modified mortars, made with Various
Indian cements conforming to Indian Standard codes (IS codes), are studied
. The maximum increase in strength, due to addition of silica fume and the
corresponding optimum silica fume content is found to be considerably less
than the same reported in the studies using cements conforming to ASTM stan
dards. This may perhaps be due to the lesser content of tri-calcium silicat
e (C3S) in Indian cements, as observed in the present study. The variation
in strength of silica fume modified mortar of various ages at high, medium
and low curing temperatures are also reported. The guidelines obtained from
these results may be useful for site application of silica fume modified m
ortar/concrete in countries with a wide variation of climatic temperatures,
like India. (C) 2000 Elsevier Science Ltd. All rights reserved.
