Abstract:

This paper describes a potential partial utilization of certain types of sludgy industrial waste, using a geotechnical engineering viewpoint. The primary objective is to investigate the potential for burning various industrial wastes combined with lime, in certain proportions, to produce a by-product having hardening characteristics similar to ordinary portland cement OPC. The potential for using this new cement-like stabilizer NCS for stabilizing loam soil is then examined. It is found that the percentages of main cementitious compounds in NCS, except alite C3S compound, are higher than in OPC. The strength of soil increases about 2 to 10 times that of remolded unconfined compressive strength i.e., 34.0 to 170.0 kNM2 as the stabilizer content and curing time are increased. The by-product thus shows promise for use in stabilizing a loam soil for subgrade purposes. Results are discussed in relation to the contribution of ettringite in strength development.
