The present invention relates to an expandable grout material having excellent rapid hardening properties and compression strength, which comprises 127 to 156 parts by weight of an accelerating agent, 10 to 13 parts by weight of polycarboxylic acid-based dispersant, 28 to 35 parts by weight of the silica fume, 57 to 70 parts by weight of calcium sulfo-aluminate, 5.7 to 7.0 parts by weight of lithium carbonate (Li_2CO_3), 3.5 to 4.5 parts by weight of an expandable graphite, 2.5 to 3.5 parts by weight of acrylic fiber, and 2.5 to 3.5 parts by weight of low-density polyethylene (LDPE), with respect to 100 parts by weight of microcement. 본 발명은 팽창성 그라우트재에 관한 것으로, 보다 상세하게는 내부 팽창성을 부여하여 팽창압에 의한 활열 주입성능을 극대화함으로서 주입성이 높을 뿐만 아니라, 속경성 및 압축강도가 우수한 팽창성 그라우트재에 관한 것이다.
