Recessed portion filling material set, cured product thereof, and recessed portion filling method

SAKAGUCHI YOICHIRO / SAITO KOHEI

Provided are a recess filling material set, a cured product thereof, and a recess filling method using the same, with which it is possible to provide a construction method or the like that eliminates construction defects such as initial adhesion to a concrete material and a steel material used in a recess. A recess filling material kit according to the present invention comprises first and second radically polymerizable resin compositions. The first radical polymerizable resin composition contains a first radical polymerizable compound (A-1), a first radical polymerizable unsaturated monomer (B-1), an acidic compound (C), and a first radical polymerization initiator (D-1). The second radical polymerizable resin composition contains a second radical polymerizable compound (A-2), a second radical polymerizable unsaturated monomer (B-2), a second radical polymerization initiator (D-2), an expanding material (J), and an aggregate (K).

提供可以提供消除与凹部所使用的混凝土制材料、钢铁制材料的初始粘接等的施工不良的施工方法等的凹部填充材料套件、其固化物、和使用其的凹部填充法。本发明的凹部填充材料套件具有第1和第2自由基聚合性树脂组合物。上述第1自由基聚合性树脂组合物含有第1自由基聚合性化合物(A‑1)、第1自由基聚合性不饱和单体(B‑1)、酸性化合物(C)和第1自由基聚合引发剂(D‑1)，上述第2自由基聚合性树脂组合物含有第2自由基聚合性化合物(A‑2)、第2自由基聚合性不饱和单体(B‑2)、第2自由基聚合引发剂(D‑2)、膨胀材料(J)和集料(K)。
