WEED-PROOF SHEET AND WEED-PROOF METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a weed-proof sheet having weed-proof effect.SOLUTION: A weed-proof sheet comprises quick-hardening powder containing calcium aluminate and gypsum of 1.3-3 in CaO/AlO(the mole ratio) filled in clearances in a three-dimensional solid sheet formed by connecting two mesh-like sheets arranged at intervals of 1-10 mm by connection yarn, where a water soluble film is laminated on one or both surfaces of the mesh-like sheets. It may also contain one or two or more selected from γ-2CaO.SiO, fly ash, silica-quality fine powder, a blast furnace slag, and limestone fine powder, or a fine aggregate.SELECTED DRAWING: Figure 1
【課題】防草効果を発揮する防草シートの提供。【解決手段】１〜１０ｍｍの間隔を有するように配置された２枚の網目状シートを連結糸でつないだ３次元立体シートの隙間に、ＣａＯ／Ａｌ２Ｏ３（モル比）が１．３〜３のカルシウムアルミネートとセッコウを含有する急硬性粉体が充填され、網目状シートの片面又は両面に水溶性フィルムを重ね合わせている防草シート。更に、γ−２ＣａＯ・ＳｉＯ２、フライアッシュ、シリカ質微粉末、高炉スラグ及び石灰石微粉末から選ばれる１種又は２種以上や細骨材を含有してもよい。【選択図】図１
