LIGHTWEIGHT CAVITY FILLER AND CAVITY FILLING METHOD USING THE SAME
To provide a lightweight cavity filler having a good filling property and fixing property and applying a load to ground and structures as little as possible among a filler for filling a hollow such as tunnel, underground cavity, and PC hollow floor slab bridge to fix a reinforcing bar, steel pipe and the like.SOLUTION: The present invention includes (1) a lightweight cavity filler containing cement, azodicarbonamide and a water soluble polymeric substance, (2) a lightweight cavity filler containing 0.05 to 10 parts by mass of the azodicarbonamide with respect to 100 parts by mass of the cement, (3) a lightweight cavity filler containing 0.01 to 1 part by mass of the water-soluble polymer substance with respect to 100 parts by mass of the cement, (4) a lightweight cavity filler in which a ratio of the water-soluble polymer substance to the azodicarbonamide is 5 to 10 parts by mass of the azodicarbonamide with respect to 1 part by mass of the water-soluble polymer substance, (5) a cavity filling method in which 50 to 150 parts by mass of water is mixed with 100 parts by mass of the lightweight cavity filler to fill the cavity. (6) a cavity filling method in which a foaming ratio is 1.5 times or more.SELECTED DRAWING: None
【課題】トンネル、地下空洞、ＰＣ中空床版橋等の中空に充填し、鉄筋、鋼管等を定着する充填材であって、充填性、定着性が良好で、地山や構造物に出来るだけ荷重がかからない軽量空洞充填材を提供する。【解決手段】（１）セメント、アゾジカルボンアミド及び水溶性高分子物質を含む軽量空洞充填材であり、（２）アゾジカルボンアミドが、セメント１００質量部に対して０．０５〜１０質量部である軽量空洞充填材であり、（３）水溶性高分子物質が、セメント１００質量部に対して０．０１〜１質量部である軽量空洞充填材であり、（４）水溶性高分子物質とアゾジカルボンアミドの割合が、水溶性高分子物質１質量部に対してアゾジカルボンアミド５〜１０質量部である軽量空洞充填材であり、（５）軽量空洞充填材１００質量部に対して、水を５０〜１５０質量部混合して空洞に充填する空洞充填方法であり、（６）発泡倍率が１．５倍以上である空洞充填方法である。【選択図】なし
