Abstract
PURPOSE: To perform the solidifying work of rubble under water or at the edge of water with high reliability by setting fresh concrete under a specific condition.
CONSTITUTION: In a cylindrical container filled with 400cc of water, 5cm in diameter and 40cm in height, 400cc of a cement paste of a water/cement ratio of 60% is flowed down from the surface of water and allowed to stand for setting. Then, sampling is made from the uppermost 5cm part and the lowermost 5cm part of the hardened cement paste and the specific gravities are measured in accordance with a testing method, and then a tackifier, e.g., polyvinyl alcohol, by which the difference in specific gravities between both the samples is made 0.1 or less by binding the cement particles is added in 0.2W4.0wt% to cement to fresh concrete. And, the fresh concrete is flowed into rubble under water or at the edge of water.
