HIGH-FLUIDITY MORTAR COMPOSITION FOR FOUNDATION TOP END
PROBLEM TO BE SOLVED: To provide a high-fluidity mortar composition for a foundation top end which hardly causes a step in a placing joint, spatula mark and initial cracking while partitioning a top end portion of a rising portion of foundation such as continuous footing or mat foundation made from reinforced concrete with a partition wall even when flowing the mortar composition into the top end portion; and to provide high-fluidity mortar for the foundation top end which hardly causes a step in a placing joint, spatula mark and initial cracking while partitioning a top end portion with a partition wall even when flowing the mortar into the top end portion.MEANS: A high-fluidity mortar composition for foundation top end contains cement, an expansive substance, a polycarboxylic acid-based cement dispersion, a thickener, a defoaming agent, and a fine aggregate. A water quantity is suitably in a specific range. A flow value measured according to a flow test method according to JASS 15M-103 by the Architectural Institute of Japan is suitably in a specific range for 30 minutes immediately after kneading.SELECTED DRAWING: None
【課題】鉄筋コンクリート製の布基礎又はベタ基礎等の基礎の立ち上がり部の天端部分に、仕切り材で仕切って流し込んでいても、打継ぎ部の段差、トンボ跡及び初期ひび割れが発生し難い基礎天端用高流動モルタル組成物を提供すること。また、天端部分に仕切り材で仕切って流し込んでいても、打継ぎ部の段差、トンボ跡及び初期ひび割れが発生し難い基礎天端用高流動モルタル。【手段】セメントと、膨張性物質と、ポリカルボン酸系セメント分散剤と、増粘剤と、消泡剤と、細骨材とを特定の割合で含有する。水量が特定の範囲内であると好適である。また、日本建築学会規格ＪＡＳＳ １５Ｍ−１０３のフロー試験方法に準じて測定したフロー値が、練り上がり直後から３０分後までの間特定の範囲内であると好適である。【選択図】なし
