Description
本発明は、セメント混和剤に関し、より詳しくは、特定の構成単位を有する2種以上のポリカルボン酸系重合体を含むセメント混和剤に関する。
ポリカルボン酸系共重合体を含むセメント混和剤は、セメントペースト、モルタル、コンクリート等のセメント組成物等に広く用いられており、セメント組成物から土木・建築構造物等を構築するために欠かすことのできないものとなっている。このようなセメント混和剤は減水剤等として用いられ、セメント組成物の流動性を高めてセメント組成物を減水させることにより、硬化物の強度や耐久性等を向上させる作用を有することになる。このような減水剤としては、従来のナフタレン系等の減水剤に比べて高い減水性能を発揮するポリカルボン酸系重合体を主成分とするポリカルボン酸系減水剤が、最近、高性能AE減水剤として多くの使用実績がある。
不飽和カルボン酸とビニルエーテル系単量体との共重合体は、優れた減水性を有するものの、経時的にセメント組成物の流動性が低下してスランプおよびスランプフローが小さくなるという問題点が残されていた。
で表される構成単位を有する少なくとも一のポリカルボン酸系重合体(A)、および下記式(2):
で表される構成単位を有する少なくとも一のポリカルボン酸系重合体(B)を含み、かつ上記ポリカルボン酸系重合体(A)と上記ポリカルボン酸系重合体(B)との重量比[(A)/(B)の重量比]が1/99〜99/1である、セメント混和剤によって達成される。
以下、本発明を詳述する。
で表される構成単位を有する少なくとも一のポリカルボン酸系重合体(A)、および下記式(2):
で表される構成単位を有する少なくとも一のポリカルボン酸系重合体(B)を含み、かつ上記ポリカルボン酸系重合体(A)と上記ポリカルボン酸系重合体(B)との重量比[(A)/(B)の重量比]が1/99〜99/1である、セメント混和剤に関するものである。
本発明の必須成分であるポリカルボン酸系重合体(A)は、式(1)の構成単位と一分子中に2個以上のカルボキシル基またはその塩を有する単量体由来の構成単位を有する重合体であり、その製造方法は特に制限されないが、本発明に係るポリカルボン酸系重合体(A)を製造する好ましい方法を以下に記載する。
本発明のもう一つの必須成分であるポリカルボン酸系重合体(B)は、式(2)の構成単位と一分子中に2個以上のカルボキシル基またはその塩を有する単量体由来の構成単位とを有する重合体であり、その製造方法は特に制限されないが、本発明に係るポリカルボン酸系重合体(B)を製造する好ましい方法を以下に記載する。

〔ポリカルボン酸系重合体(B−4)の製造〕
温度計、攪拌機、滴下装置、窒素導入管及び還流冷却管を備えたガラス製反応装置に水573.5部を仕込み攪拌下に反応装置内を窒素置換し、窒素雰囲気下で60℃まで昇温した。続いて表1に示す単量体(b−3)545.7部、メタクリル酸108.0部、48%水酸化ナトリウム水溶液11.8部、3−メルカプトプロピオン酸9.76部及び蒸留水148.6部を混合したモノマー水溶液を4時間で、3.7%過酸化水素水50部及び4.7%L−アスコルビン酸水溶液50部をそれぞれ5時間で滴下した。その後1時間引き続いて60℃を維持し、重合を完結させ、重量平均分子量13100のポリカルボン酸系重合体(B−4)の水溶液(固形分濃度45重量%)を得た。
製造例1で製造したポリカルボン酸系重合体(A−1)および製造例2〜5で製造したポリカルボン酸系重合体(B−1)〜(B−4)および表2に示す構造のセメント混和剤(A)、(B)を、表3に示す配合で混合し、本発明のセメント混和剤(1)〜(3)を得た。これら本発明のセメント混和剤(1)〜(3)を用い、コンクリート試験を行い、添加量と経時後のスランプおよびスランプフローの変化を評価した。結果を表4に示した。
製造例1で製造したポリカルボン酸系重合体(A−1)のみからなる比較セメント混和剤(1)を用い、コンクリート試験を行ない、添加量と経時後のスランプおよびスランプフローの変化を評価した。結果を表4に示した。
製造例2で製造したポリカルボン酸系重合体(B−1)のみからなる比較セメント混和剤(2)を用い、コンクリート試験を行ない、添加量と経時後のスランプおよびスランプフローの変化を評価した。結果を表4に示した。
製造例3で製造したポリカルボン酸系重合体(B−2)のみからなる比較セメント混和剤(3)を用い、コンクリート試験を行ない、添加量と経時後のスランプおよびスランプフローの変化を評価した。結果を表4に示した。
実施例1〜3、及び比較例1で示したセメント混和剤を用いて、下記に示す配合でコンクリートを調合・混練し、所定のスランプフロー値を得るための混和剤添加量と、混練直後(すなわち0分後)、混練30分後および混練60分後のスランプ値およびスランプフロー値を評価した。
配合単位量は、水175kg/m3、セメント389kg/m3、粗骨材941kg/m3、細骨材791kg/m3とした。
住友大阪セメント社製普通ポルトランドセメント
太平洋セメント社製普通ポルトランドセメント
粗骨材:青森県八戸産石灰砕石
細骨材:千葉県君津産山砂
消泡剤であるMA404(ポゾリス物産製)をセメント重量に対して0.005%配合した。
上記配合で、50L強制練りミキサーにセメント、細骨材、粗骨材を投入して10秒間空練を行い、次いで、セメント混和剤を配合した水を加えて更に120秒間混練を行い、コンクリートを製造した。
得られたコンクリートのスランプ値およびスランプフロー値測定は日本工業規格(JIS A1101、1128、6204)に準拠して行った。
上記表4から、実施例1〜3で使用した本発明のセメント混和剤(1)〜(3)を用いたコンクリートはいずれも、比較例2及び3で使用した比較セメント混和剤(1)及び(3)を用いたコンクリートに比して、少ない添加量で所定のスランプフロー値になるまでセメントを分散・流動させることができており、優れた減水性を示している。なおかつ、比較例1及び2で使用した比較セメント混和剤(1)及び(2)を用いたコンクリートより混練30分後および混練60分後のスランプ値およびスランプフロー値の低下が少ないので、経時後の流動性が悪化しにくくなっていることが判る。
本発明のセメント混和剤は優れた減水性を有し、なおかつ経時的にセメント組成物の流動性が低下してスランプおよびスランプフローが小さくなるのを抑制するため、本発明のセメント混和剤を用いることにより、セメント硬化物が作業効率よく形成・製造できるので、強度および耐久性に優れた土木建造物や建築建造物を構築する上で、多大な役割を果たすものである。
