title = "Testing of long-term geotechnical parameters of by-products in laboratory",
abstract = "The properties of four by-products were determined in this research project.These by-products were cement stabilised fly ash, blast-furnace slag sand, mixture of fly ash and de-sulphuration product and cement stabilised wood or peat ash.The properties considered critical in relation to long-term stability were determined in the laboratory.The results obtained were compared against the requirements set on by-products used in road construction.One of these tested materials has also been used in a test section built before these tests were started.All materials tested are in principle capable of producing adequate compressive strength and stiffness to be used in road construction. In practice some problems may arise especially concerning the choice of parameters for design due to poor environmental durability.In other words stabilised or self-strengthening materials do not necessarily last as intact the repeated freeze thaw cycles.Although the stiffness of stabilised material decreases significantly do to structural failure it may still possess reasonable large stiffness to be used in sub-base of a road structure.",
