| Abstract: | Studies were made on cement concrete and cement-fly ash concrete mixes incorporating wollastonite as partial substitute
of cementitious material and sand respectively. Improvements in compressive (28-35%) and flexural strength (36-42%) at 28
and 56 days respectively were observed by incorporation of wollastonite (10%) in concrete mixes. By incorporation of
wollastonite, reduction in water absorption, drying-shrinkage and abrasion loss of concrete, and enhancement in durability
against alternate freezing-thawing and sulphate attack were observed. Because of high concrete strength and abrasion resistance,
a better utilization of concrete cross section is possible. Alternatively, thickness of pavement slab can be reduced by incorporation of wollastonite micro-fibres in concrete mixes. |
