<p>PROBLEM TO BE SOLVED: To provide a curable composition which has such an excellent durability that, even when applied to joints having large movements in exterior walls of a building, cracks and peeling do not occur for a long period and a good condition can be maintained.SOLUTION: There is provided a sealing material for construction including: (A) a mixed polyoxyalkylene polymer (A) containing a polyoxyalkylene polymer (A1) of a linear structure having a reactive silicon group which can crosslink by forming a siloxane bond, and a polyoxyalkylene polymer (A2) of a branched structure having a reactive silicon group which can crosslink by forming a siloxane bond in a ratio of (A1):(A2)=1:100 to 100:100; heavy calcium carbonate (B); colloidal calcium carbonate (C); microballoons (D); a plasticizer (E); an epoxy compound (F): and further a compound (X) which generates trimethyl silanol upon hydrolysis; a drying oil (Y); and a photocurable substance (Z).</p> |
