Description
・6、8、10、12、14、16、20、25、28、32および40mmの直径および18mまでの送り長さを有するリブ付き熱間圧延棒鋼としての、コンクリート用棒鋼B500B(DIN 488による)(旧「BSt 500 S(B)」)、
・リブ付きでかつ異形の冷間加工鋼棒(延性等級A)または熱間圧延コンクリート用鋼(延性等級B)を構成要素とし、かつ6mm〜14mm(高延性のバージョンにおいてのみ14mm、通常の延性または高延性のバージョンにおいては6〜12mm)の直径を有する完成溶接格子としての、様々なバリエーションでのコンクリート用鋼格子B500AおよびB500B(DIN 488による)(旧「BSt 500 M(A)および(B)」)、
・特に半完成天井部品および半完成壁部品における曲げ強さの補強材としての、格子状支持体。
− 混合ヘッド回転数 300rpm
− 系のエア圧 約2バール
− 材料処理量 120L/時間。
本発明による天井要素のサイズは、1m×1.5m×0.12mである。まず、100mm×100mmのメッシュサイズを有する鉄筋格子B500A(DIN 488による)を対応する型枠に取り付け、その際、鋼棒は6mmの直径を有するものとする。続いて、この補強材上に、上述の通りにして得られるジオポリマー発泡体をストリップ状に吹付け、かつ25℃、空中湿度80%で2時間乾燥させ、次いでコンクリートを打設する。この天井要素を製造するために、8mmの最大粒径を有する強度クラスC25/30の現場打ちコンクリートを選択する。フレッシュコンクリートは、2328kg/m3の密度およびF5のコンシステンシー等級を有する。
実施例2は、補強材として格子状支持体が使用される点で実施例1と異なる。
