PURPOSE:To use an ultrafine slurry of a high flowability without a problem in storage with an ease of measurement and transport to obtain a structure having an impermeability to rainwater and a large strength. CONSTITUTION:An ultrafine slurry is prepared by previously kneading ultrafine powder with water in a water/ultrafine powder ratio of 0.8-1.2. The ultrafine slurry is added to a mixture of an aggregate, a cement, and water to be prepared as an ultrafine powder curing material 4. The ultrafine slurry contains 25-50% water per total amount of water in use, 8-15% ultrafine powder per weight of cement, and 0.5-5% water reducing agent per weight of cement. A ratio of total amount of water in use to cement is 0.25--0.3. The obtained ultrafine powder curing material 4 is placed between form plates 3, 3 to form a structure for a slope stabilizing work. In this manner, the ultrafine slurry containing a relatively large amount of water can be easily kneaded and also easily transported and weighed. The water/ultrafine powder ratio of 0.8-1.2 prevents the ultrafine powder from being set or separated from water under storage and ensures a predetermined water/cement ratio. The ultrafine powder curing material has a high particle density, thus preventing water from infiltrating inside. |
