Investigation on Mechanical Properties of Clay-Based Material Prepared from the Yellow River Silt
The Yellow River silt is a kind of sedimentary sandy soil which comes from the loess plateau carried by the steam of Yellow River. In order to utilizing silt and saving resource, investigation and analysis of characteristics Yellow River silts from the lower reaches area were performed, and clay-based cementitious material were prepared from Yellow River silt as main raw material, and a few of cement, lime and excitant agent as auxiliary materials. The mechanical properties and water resistances of clay-based cementitious material were studied. The results shows that: The clay-based cementitious material which is activated by composite excitant agent composed of sodium hexametaphosphate, calcium chloride and sodium silicate, have favorable mechanical and physical properties, especially favorable water-resistance. The specimen compressive strength is 21.2MPa after curing for 28d and with a softening coefficient 0.78, which cement content is 10% and excitant agent content is 4%.
