Experimental Study on Mechanical Properties of Soft Soil Cured by a New Compound Curing Agent
Coastal areas are unable to support ground construction when there is too much soft soil content,and it is important to study the effect of curing agents on improving the mechanical properties of soft soil for its field application.Using water glass and sodium hydroxide as the exciter and slag and fly ash as the curing agent,the effects of different material admixtures on the compressive strength of sandy soft soils in coastal areas of Guangdong were investigated.The results showed that when the slag doping amount exceeded30%,the influence of slag on the curing effect became larger and the compressive strength of cured soil increased substantially.With the increase of exciter dosage,water-glass modulus,water-cement ratio and soft soil sand content,the compressive strength of the cured soil all increased firstly and then decreased,and the optimum dosage existed.The peak compressive strength of cured soil corresponds to the dosing of each material:30%of exciter,1.0 of water glass modulus,0.25 of water cement ratio and 20%of sand content.
