ABSTRACT
The annualized economic burden to United States in 2016 from wildfire is estimated to be between $71.1 billion and $347.8 billion. The cost of wildfire to Indian economy is at least USD148 million (₹1,100 Crores). One of the plants with high associated risk to wildfire is Calotropis Procera (CP). Thus, there is a great opportunity to explore materials which upkeep the good health of forest eco system, stabilize soil slopes in forest areas and serve as an alternative material for construction. Current research focuses towards application of various industrial wastes. There is a lot of scope for exploring the potential of re-using the residue collected from wildfires in the areas surrounding forest. There is an adequate scope to raise an alternative material to cement to reduce carbon emissions and achieve sustainability of resources used in the manufacture of cement. India has 10.6% of the hill- slopes covered with laterite soils which are prone to frequent slope failures. In the present study, an innovative combination of materials "1) Ash of Calotropis Procera plant (Highly inflammable) – ACP (Derived from forest fires) and 2) Metakaolin – MET (An alternative cementitious material) were utilised to stabilize lateritic soil-LS. Proctor heavy compaction test was conducted to study the minimum water content required to achieve the highest value of unit weight of the resulting combinations. Various proportions of ACP used were "2%, 4%, 6%, 8% & 10%". Various proportions of MET used were "0.2%, 0.4%, 0.6%, 0.8% & 1.0%". Out of five combinations of Laterite soil(LS), Ash produced by burning Calotropis Procera (ACP), and Metakaolin (MET), the combination-3 i.e., LS+ 6% ACP + 0.6% MET gave rise to the highest value of unit weight in heavy compaction. The optimum moisture content achieved is 12% and the highest value of unit weight achieved is 20.8 kN/m3.
