PURPOSE : A method for preparing a soil with high fluidity is provided to reduce the cost of buying earth and sand by utilizing spoil earth of a construction field without using aggregate depending on a natural resource such as sand and gravels and obtain the soil with high fluidity of which self-leveling, self-compacting, fluidity, and artificial strength control are possible, thereby influencing little on surrounding environment. CONSTITUTION : A method for preparing a soil with high fluidity comprises a step of classifying collected samples using a USCS(unified soil classification system) into SW, SM, SC, ML, and CL and mixing each of the samples with water and a solidifying agent and is characterized in that if the sample is SW, the field soil fertilizer is 53.3%% and the ratio of water and a solidifying agent is 209-215%%, if the sample is SM, the field soil fertilizer is 60.0%% and the ratio of water and a solidifying agent is 189-195%%, if the sample is SC, the field soil fertilizer is 43.5%% and the ratio of water and a solidifying agent is 204-210, if the sample is ML, the field soil fertilizer is 38.8%% and the ratio of water and a solidifying agent is 238-244%%, and if the sample is CL, the field soil fertilizer is 53.3%% and the ratio of water and a solidifying agent is 209-215%% and it includes 15.5 grams of a promoting agent. © KIPO 2008
