“…Due to introduction of these ashes, soil also undergoes cationic changes and soil structure changes as a result of particles agglomeration, which results in smaller dry density and greater optimal moisture content of the mixture. This effect is also due to lower density of bioash and more porous particles of larger specific area that require larger amounts of water, and so the same effect can also be seen in ashes with higher SiO2 content, such as the ash from rice husk [35,36] and ash from sawdust [37]. The introduction of bioash into coherent soils often reduces the plasticity index [33][34][35][36].…”

Bioashes are inevitable product of meeting the demands to satisfy the increased use of renewable resources in energy production. Ecological and economic problems of bioash disposal, due to its appropriate chemical and physical properties, can be reduced by its application in the construction industry as raw materials. The paper therefore provides an research overview on various aspects of the bioash application in road construction, in compliance with a range of properties depending on the type of biomass and the conditions of combustion. Also shown is current state of research of bioash generated in the domestic thermal power plants.

“…Different investigators have worked on the various geotechnical properties of soils [3][4][5][6][7][8][9][10][11], burnt clay bricks [12] and highway subgrade [13][14] stabilized using SDA. However, Butt et al [4] and Raheem et al [15] indicate SDA to be a pozzolanic material due to its high siliceous content. A pozzolan is a material of finely divided siliceous or aluminous composition which forms cemented products in the presence of water and calcium hydroxide [16].…”

The investigation evaluated the strength benefits obtained by amending cement stabilization of an expansive soil by using saw dust ash (SDA), a waste generated in wood milling industries due to burning. The experimental program involved the preparation of cylindrical specimens of size 38 mm x 76mm for evaluating the unconfined compression strength (UCS) of the cement stabilized and amended samples cured for varying periods of 2 hours, 7, 14 and 28 days. Two cement contents of 2% and 6% by weight of soil were adopted to stabilize the soil. The SDA amended cement stabilized samples adopted SDA contents of 5%, 10% and 20% by weight of soil. Strength gain trends for the amended samples were also fitted based on the results of the UCS tests. In order to analyse benefits in pavement design and thickness reduction, the UCS values were used to predict the CBR value of the specimens based on which the reduction in pavement thickness was calculated for different traffic densities. The investigation revealed that 5% SDA amendment of cement stabilization can result in up to 26% increase in early strength and 20% increase in delayed strength. Based on the predicted CBR values, pavement thickness can be reduced up to 8.3%.

This research is aimed at using Snail Shell Powder (SSP) and Palm Kernel Shell Powder (PKSP) in stabilizing clay. Elemental and oxide compositions of the powders were determined and they revealed SSP is richer in CaO than PKSP. Sieve Analysis, Compaction, California Bearing Ratio (CBR) and Atterberg Limit were conducted on natural and stabilized soil mixture. The natural soil (A-7-6) was blended with SSP and PKSP at varying proportion of 2%, 4%, 6%, 8%, and 10% by dry weight of soil respectively and also combined at ratios not more than 10% total . Inclusion of additives increase the Maximum Dry Density (MDD) while it predominantly decrease the Optimum Moisture Content (OMC) values of the stabilized soil mixture. Plasticity Index (PI) decrease with the addition of the powders with the best performance observed mostly with SSP blended soil. It was also found that the CBR values of soil increase with corresponding increase in dosage of the powders. Soil blended with 8% SSP offered the best result with increase in MDD from 1198 to 1300kg/m 3 while the combined additives gave the best result at 2%SSP+8%PKSP addition with MDD increasing to 1266 kg/m 3 and further reduction of OMC to 21%. The best results in PI were from Soil blended with 2% SSP and also 2%SSP+8PKSP with 6.25% and 9.2% respectively. For CBR, soil blended with 8% SSP and 2%SSP+8PKSP of combined ratio gave peak performances. The potential of these additives in improving soil properties and reducing construction cost of road are presented.
