説明

The preliminary mortar pumping has been recommended so as to assure lubrication between pipes and concrete slurry. However, technical parameters for the mortar actually employed in practice have not been surveyed so far. Research on the state-of-the art of the preliminary mortar pumping was made on the basis of 267 respondents over the country in addition to our own experiments. As a result, method, material and amount of the preliminary mortar pumping were reexamined, and the possible means to reduce it is presented.
