の施工法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to anhydrous gypsum compositions for cast flooring and a method for applying the same, and more specifically, the present invention relates to anhydrous gypsum compositions for cast flooring and methods for applying the same. The present invention relates to a composition comprising the same and a method for applying the same.
ＩＩ型無水石膏は、水を加えても直ちに工水石膏となら
ないため、硬化に極めて長時間を要するので、硫酸カリ
ウムなどのいわゆる硬化促進剤の助けを借りて比較的短
時間に硬化させられる。Type II anhydrite does not immediately turn into water gypsum even when water is added to it, so it takes a very long time to harden, so it can be hardened in a relatively short time with the help of a so-called hardening accelerator such as potassium sulfate.

面形成材に用いられている。Type 11 anhydrite contains calcium hydroxide or calcium oxide in an amount of 0.2 to 0.2 of the gypsum in terms of calcium hydroxide.
5% by weight, 0.5 to 7.5% by weight of an accelerator, and other additives (for example, a fluidizing agent) as appropriate for use in floor forming materials.
すなわち、この組成物に水を加えてスラリーとし、これ
を床面上に流し延べ、自然乾燥して床面を形成する。That is, water is added to this composition to form a slurry, which is poured onto a floor surface and air-dried to form a floor surface.

設におり−ては、床面の形成に続けて、たとえばＰタイ
ル張りを施工し、工期を短縮することが望まれている。The type II anhydrite composition is thus used to form a floor surface, but at that time, the formed floor surface hardens early, making it difficult to process the floor surface, such as P tiling, at an early stage. It is requested that the force end with 5. For example, in the construction of a building, it is desired to shorten the construction period by constructing, for example, P tiles after forming the floor surface.
