description	PROBLEM TO BE SOLVED: To provide a calculation method of a coagulation start time, by an operation more rapid and simple than a coagulation test by JIS R 5201 requiring a skilled technology and much time.SOLUTION: The electric conductivity of a cement suspension is temporally measured using an electric conductivity meter. On the basis of the result, a coagulation start time equivalent to a coagulation start time measured by JIS R 5201 is calculated.SELECTED DRAWING: Figure 4 【課題】熟練した技術と時間を要するJIS R 5201による凝結試験よりも、迅速で、簡便な操作による凝結始発時間の算出方法を提供する。【解決手段】電気伝導率メータを用いてセメント懸濁溶液の電気伝導率を経時的に測定し、その結果からJIS R 5201で測定される凝結始発時間と同等の凝結始発時間を算出する。【選択図】図４
