Abstract: The paper addresses certain issues pertaining to the technology of lime-stabilised steam-cured blocks used for masonry construction.
Properties of lime-stabilised steam-cured blocks using expansive soils and tank bed soils have been xamined.
Influence of parameters like steam curing period,lime content and fly ash content on wet strength of blocks is studied.
Steam curing of lime stabilised blocks at 80 °C for about 20 hours at atmospheric pressure leads to considerably higher strengths when compared with curing under wet cloth at ambient temperatures.
Clay-fly ash fractions of the mix control the optimum lime content yielding maximum strength.
Long-term strength behaviour of steam-cured blocks has been monitored.
The results indicate a favourable limeclay ratio for stable long-term strength.
A small-scale steam cured block production system has been designed and implemented to construct a load bearing masonry structure,thus demonstrating the potential of steam-cured block as a material for masonry construction.
