Mortar manufacturing method to prevent cracking of plaster mortar for Ondol

摘要

1. TECHNICAL FIELD OF THE INVENTION;The present invention relates to a method of manufacturing mortar for preventing cracking of plaster mortar in Ondol construction.;2. Technical Problems to be Solved by the Present Invention;In hydration reaction of cement in mortar, more hydration products are generated, thereby imparting swelling property to cement particles, thereby reducing pores between cement particles and fundamentally preventing cracking of plaster mortar.;3. Points of Solution of the Invention;In producing the Ondol mortar by mixing a predetermined amount of cement, sand and water, a predetermined amount of calcium sulfate (CaSO 4) is added to the above-₄) Are mixed to produce a floor mortar for ondol.;4. Important Uses of the Invention;Used for Ondol construction.
