WEED-PROOF MATERIAL AND APPLICATION METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a weed-proof material and an application method thereof which exhibits a short hardening time, high initial strength development, greatly improved freeze-thaw resistance, small environmental load, sustainability in weed-proof performance, and suitability in environmental conservation.SOLUTION: Provided is an application method of a weed-proof material including: (1) a weed-proof material containing calcium aluminate, calcium sulfate, hollow body, and soil; (2) a weed-proof material according to (1), in which a density of the hollow body is 0.02 to 0.2 g/cm; (3) a weed-proof material according to (1) or (2), in which CaO/AlOmolar ratio of the calcium aluminate is 1.0 to 3.0 and foreign matter content is 15% by mass or less; (4) a weed-proof material according to any one of (1) to (3), further containing calcium silicate; (5) an application method of a weed-proof material, in which the weed-proof material according to any one of (1) to (4) is laid to coat the ground by sprinkling water thereon; and (6) the application method of the weed-proof material, in which the weed-proof material according to any one of (1) to (4) is kneaded with water and laid to coat the ground.SELECTED DRAWING: None
【課題】硬化時間が短く、初期強度発現性が高く、凍結融解抵抗性を著しく改善し、環境負荷の低い、防草の持続性と環境保全に好適な防草材及びその使用方法を提供する。【解決手段】（１）カルシウムアルミネート、石膏、中空体及び土壌を含有してなる防草材、（２）中空体の密度が０．０２〜０．２ｇ／ｃｍ３である（１）の防草材、（３）カルシウムアルミネートのＣａＯ／Ａｌ２Ｏ３モル比が１．０〜３．０、不純物含有量１５質量％以下である（１）又は（２）の防草材、（４）さらに、カルシウムシリケートを含有してなる（１）〜（３）いずれかの防草材、（５）（１）〜（４）のいずれかの防草材を地面に敷き詰めてその上に散水して被覆する防草材の使用方法、（６）（１）〜（４）のいずれかの防草材を水で練混ぜて地面に敷き詰めて被覆する防草材の使用方法である。【選択図】なし
