Abstract
An attempt is made in the field of high performance self-compacting cementitious system to have an eco-friendly construction material utilizing raw materials, in this case wood waste sawdust. Two different types of wood sawdust (SD) namely, kikar (Vachellia Nilotica) sawdust (KSD) and partal (Abies pindrow) sawdust (PSD) were used with neat Portland cement paste system in replacement mode. The replacement of SD was 3%, 5% and 7% in each case. results showed a consistency in the slight decrease of compressive strengths, the reduction in shrinkage with samples having sawdust (SD) were highly significant. the effect of water and air curing along with the water absorption capacity of sawdust in powder form and the comparison of water uptake of self-compacting paste samples with and without sawdust at different days during wet curing showed that sawdust has the potential to serve as an internal curing agent in self-compacting cementitious system.
