CEMENT MIXING MATERIAL AND/OR MIXING AGENT PACKAGE AND METHOD FOR ADDING THE SAME

摘要

PURPOSE:To simply adding a cement mixing material to a cement mixture and to dispense with the treatment of a mixing material container by filling a packing material containing a fibrous material and broken within the cement mixture with the mixing material and/or mixing agent for the cement mixture to omit weighing labor. CONSTITUTION:A carboxyl group-containing polymer and a fibrous substance are compounded and the resulting dispersion is diluted and sufficiently stirred to be formed into a handmade sheet. The obtained sheet is dried to produce an alkali hydrolyzable sheet wherein the fibrous substance and fibrous carboxymethyl cellulose are mixed. By this method, a cement mixing material can be formed into a package by a predetermined amount in matching relation to the standard preparation of a cement compsn. such as concrete or mortar and weighing labor at the time of use can be omitted. Further, the spilling or scattering of the mixing material on the work spot is eliminated and a weighing device or a charging device is unnecessary and control is easy.
