Description
<発泡性液状混和材の作製>
以下に表す(A)〜(D)から選定される材料を用い、表1に表す配合割合となるよう、約20℃の温度下でハンドミキサを用い約2分間混合することによって液状混和材を作製した。作製した液状混和材はポリエチレン製容器中で蓋を閉めて24時間又は60日間放置した。
(B1)低級アルコールのアルキレンオキサイド付加物(商品名「太平洋テトラガード」、太平洋マテリアル社製)
(B2)菜種油(市販品)
(C1)エチレングリコール(市販試薬)
(C2)ジエチレングリコール(市販試薬)
(C3)プロピレングリコール(市販試薬)
(C4)エタノール(市販試薬)
(C5)水
(D)生石灰(ブレーン比表面積3000cm2/g)
前記の液状混和材および以下表す(E)〜(H)と水から選定される材料を用い、表2に表す配合のモルタル混練物を作製した。モルタル混練物の作製手順は、水を除く各材料を3リットル容積のホバートミキサに一括投入し、約10℃と20℃の温度下で、低速で10秒間混合の後、水を加え、引続き低速で30秒間混練を行った。また、比較のため液状混和材に代えて(A)と同じ流動コークス粒子をそのまま配合使用したモルタル混練物(参考品15)も同様の方法で作製した。
(F)ナフタレンスルフォン酸系高性能減水剤(商品名「マイティ100」、花王社製)
(G)細骨材(北海道上磯産砕砂、F.M.=2.64)
(H)セルロース系増粘剤(商品名「メトローズhi90SH−4000」、信越化学工業社製)
前記のモルタル混練物から、直径5cm、高さ10cmの円柱状試験体を型枠成形し、10℃で混練したモルタルから得た試験体は10℃の恒温室に保管し、20℃で混練したモルタルから得た試験体は20℃の恒温室に保管し、20℃で保管した材齢7日目の試験体の圧縮強度をJIS A 1108に準拠した方法で測定した。また、10℃と20℃の恒温室において、それぞれ日本道路公団企画JHS−312の膨張収縮試験方法に準拠した方法で膨張収縮率を測定した。以上のモルタル試験体の測定結果は表3に表す。
