EARLY STRENGTH TYPE SHOTCRETE COMPOSITE
The present invention provides, as a cement composition, an early strength type cement composition having fineness of 4,300 to 4,600 cm^2/g and SO_3 content of 3 to 3.4 wt%, and a shotcrete composition comprising coarse aggregate; fine aggregate; cement; water; a water-reducing agent; and an accelerating agent. The coarse aggregate has the maximum diameter of 10 mm. 570 to 680 kg/m^3 of the coarse aggregate and 950 to 1100 kg/m^3 of the fine aggregate are mixed, wherein the ratio of the fine aggregate is 60 to 65%. As the early strength type cement composition, 430 to 500 kg/m^3 of the cement and 190 to 220 kg/m^3 of the water are mixed, wherein the ratio of the water and the cement is 43.5 to 46%. In addition, as a high performance water-reducing agent (AD), 0.9 to 1.1 parts by weight of the water-reducing agent are mixed based on 100 parts by weight of the cement, and 5 to 7 parts by weight of the accelerating agent are mixed based on 100 parts by weight of the cement.
본 발명은 「시멘트 조성물로서, 분말도가 4,300~4,600㎠/g이고, SO의 함량이 3~3.4wt%인 것을 특징으로 하는 조강형 시멘트 조성물」 및 「굵은골재; 잔골재; 시멘트; 물; 감수제 및 급결제를 포함하고, 상기 굵은골재는 최대 직경이 10㎜로서 570~680㎏/㎥로 배합되고 상기 잔골재는 950~1100㎏/㎥로 배합되되 잔골재율은 60~65%로 배합되고, 상기 시멘트는 상기 조강형 시멘트 조성물로서 430~500㎏/㎥로 배합되고 상기 물은 190~220㎏/㎥로 배합되되 물시멘트비는 43.5~46%가 되도록 배합되고, 상기 감수제는 고성능 감수제(AD)로서 상기 시멘트 100중량부 대비 0.9~1.1중량부 배합되며, 상기 급결제는 상기 시멘트 100중량부 대비 5~7중량부 배합된 것을 특징으로 하는 숏크리트 조성물」을 제공한다.
