Abstract

Abstract

To mitigate a series of issues accompanied by cement production such as high consumption of natural resources and energy and environmental pollution, calcium carbide residues (CCR) and ground granulated blast-furnace slag (GGBS) were designed to develop alkali-activated cementitious materials made from all solid wastes, which could totally replace cement. A test for waterproof curtains by the jet grouting method with the alkali-activated cementitious material made from all solid wastes was conducted. The workability, water permeability and strength characteristics of alkali-activated cementitious material made from all solid wastes with different proportions were studied. The test results indicated that compared with using cement, when alkali-activated cementitious materials made from all solid wastes were adopted, the nozzle diameter of jet grouting machines should be increased and the water content of undisturbed CCR should be maintained to keep the pipeline unblocked during construction. Excavation inspection after jet grouting found that there was no leakage on the curtain and the curtain met the design requirements, and the permeability coefficient of the waterproof curtain made from alkali-activated cementitious materials was slightly smaller than that made of cement. The strength of waterproof curtains jet grouted with the alkali-activated cementitious material made from calcium carbide residues and ground granulated blast-furnace slag in the mix proportion of 1∶2 was less than jet grouted with cement. However, when the calcium carbide residue and ground granulated blast-furnace slag in the mix proportion of 1∶1, the strength of curtains at early ages was slightly higher than that jet grouted with cement, the strength was significantly higher at later ages.
