<P>PROBLEM TO BE SOLVED: To provide a mortar composition and a construction method therefor capable of performing unevenness adjustment of 2-25 mm of a concrete structure formwork surface placed by using a formwork, and surface finishing which is strong against efflorescence, neutralization and shrinkage crack and which has fine appearance performance, efficiently at one time with excellent work efficiency by an application process by using a trowel or a spatula. <P>SOLUTION: A mortar composition material is used, which comprises cement, a resin, titanium oxide, an expansive additive, a higher fatty acid, a fine aggregate, an inorganic pigment and water as main components for the composition, and which is formed by adding the fine aggregate, the inorganic pigment and water to a mixture obtained by adding a 2-8 pts. wt acrylic re-emulsified powder resin, 3-20 pts. wt titanium oxide, a 2-10 pts. wt expansive additive, and a 0.1-3 pts. wt higher fatty acid to 100 pts. wt cement. In the construction method, the mortar composition is applied by using a trowel or a spatula. <P>COPYRIGHT: (C)2013,JPO&INPIT |
