CEMENT ADMIXTURE AND/OR ADDING METHOD OF ADMIXTURE, AND CEMENT ADMIXTURE AND/OR ADMIXTURE PACKAGE BODY

摘要

PURPOSE:To enable the addition quantity to be adjusted by the number of a packaged admixture (agent), and render intricate operations such as measuring, putting, or the like unnecessary by putting and then stirring packaged bodies, in which a cement admixture is housed in a vessel, into cement slurry, and thus adding and mixing the admixture (agent) into the cement slurry. CONSTITUTION:A cement admixture (agent) 17 is sealed and filled into a vessel 13 in consequence forms a packaged body 11. The vessel 13 has configurations that resemble a one-way type of paper package for milk and, since it is not required to provide a take-off port, the upper part thereof is simplified. When the package 13 is put into a mixer or the like, the package 13 is destroyed and opened by the shearing force of stirring and therefore the admixture (agent) is discharged therefrom and mixed into the cement slurry. On the other hand, broken pieces of the package 13 are dispersed into the cement slurry. In the case of employing water soluble paper, water soluble fibers and the like as a material of the package 13, by the dissolution of the package 13, the admixture (agent) 17 is discharged and added to the cement slurry.
