Description
本出願は、その開示が、その全体において本明細書に組み込まれている先の2008年10月10日に出願された米国特許仮出願第61/104661号明細書の利益を享受するものである。
本明細書において開示されているのは、一般的建造物および高級な建造物の両方に使用される普通のポルトランドセメント(例えば、I型およびII型セメント)に取って代わることができる高早期強度発現ポゾランセメントである。本発明のポゾランセメントには、独特の分布のポゾランおよび水硬性セメント粒子が含まれ、そこではより大きなサイズの粒子が大部分または専らポゾランを含み、より小さなサイズの粒子が大部分または専ら水硬性セメントを含む。ポゾランの水和を行うのに必要とされる水酸化カルシウムは、水硬性セメント部分からの余分のカルシウムによって提供される。その結果は、優れた長期強度および耐久性と共にOPC同様の高い早期強度発現性、ならびにより低いコストおよびCO2出力を提供するセメント組成物である。
A.粒度分布
完全球形粒子の粒径は、直径により測定される。フライアッシュはそれが形成される方法のために、一般に球状であるが、ポルトランドセメント粒子およびポゾラン粒子は球状ではない可能性がある。したがって、「粒径」は、粉砕されたまたは他の方法による非球状材料、例えばポルトランドセメントおよび多くのポゾランなどの粒径を測定する許容された方法により測定するものとする。試料の粒径は、目視評価により、または1組のふるいの使用によって測定することができる。粒径は、光学または電子顕微鏡解析により個別に測定することができる。粒度分布(PSD)は、レーザーまたはX線回折(XRD)によって測定もしくは評価することもできる。
「ポルトランドセメント」とは一般に、ケイ酸三カルシウム(「C3S」)、ケイ酸二カルシウム(「C2S」)、アルミン酸三カルシウム(「C3A」)および鉄アルミン酸四カルシウム(「C4AF」)を、非特許文献1および非特許文献2に示されているような規格により制定された規定の量で含有する、粉砕された粒子状材料を指す。本明細書において使用される用語「水硬性セメント(hydraulic cement)」とは、4種のクリンカー材料(すなわち、C2S、C3S、C3AおよびC4AF)の1種または複数を含有するポルトランドセメントおよび関連する水硬性の凝結可能な材料であって、高含量のケイ酸三カルシウムを有するセメント組成物、普通のポルトランドセメントと化学的に同様のもしくは類似しているセメント、ならびに、非特許文献3規格中に含まれるセメントを含む、ポルトランドセメントおよび関連する水硬性の凝結可能な材料を指すものとする。
ポゾランは通常、水分の存在下において常温で遊離石灰と結合して、接着性状を有する安定な不溶性化合物を形成するであろう成分を含有する材料と定義される。ポゾランは、天然および人工の2つの群に分けることができる。天然ポゾランは、一般に火山起源の材料であるが、珪藻土が含まれる。人工ポゾランは、主として粘土および頁岩ならびにある種のシリカ質岩石などの天然材料の熱処理によって得られる生成物、ならびに微粉末燃料灰(例えば、フライアッシュ)である。
上記において検討したように、ケイ酸三カルシウムを含有するポルトランドセメントなどの水硬性セメントは、ポゾランとの反応に利用可能な余分の水酸化カルシウムを典型的に提供するであろう。水硬性セメント中のケイ酸三カルシウムの相対的割合、およびポゾランセメント組成物内の水硬性セメントの相対的量に応じて、ポゾラン部分との反応のための追加的水酸化カルシウムを提供するために、補助用石灰(例えば、酸化カルシウムまたは水酸化カルシウム)が含まれることが望ましいであろう。補助用石灰の量は、ポゾランの量およびカルシウムの不足に応じて、全体のポゾランセメント組成物の約0〜30重量%、もしくは約2〜25重量%または約5〜20重量%まで変動できる。
III.粒度を最適化したセメントおよびポゾランを得る
所望の粒度分布および/または粉末度を有する水硬性セメントおよびフライアッシュを得るための任意の知られている方法を、本発明の範囲内で使用することができる。一般に、粒度を最適化した水硬性セメントは、所望の粒度分布を有するようにセメントクリンカーを粉砕および分級するステップによって得ることができる。
IV.セメント系組成物
本発明のポゾランセメント組成物は、コンクリート、モルタル、グラウト、成形組成物、または他のセメント系組成物を作るのに使用することができる。一般に、「コンクリート」は、水硬性セメント結合材と、細骨材および粗骨材(例えば、砂および岩石)などの骨材とが含まれるセメント系組成物を指す。「モルタル」には、典型的にセメント、砂、および石灰が含まれ、煉瓦またはコンクリートブロックの重量を支えるのに十分な剛性を有することができる。「グラウト」は、コンクリート構造物中の亀裂または割れ目、構造体の間の空間、およびタイル間の空間などの空間を充填するのに使用される。「成形組成物」は、ポット、トラフ(樋)、ポスト(支柱)、噴水、装飾石などの成形もしくは注型物を製造するのに使用される。
下記の実施例は、過去時制で表現される場合、実際に調製されている本発明の実施形態を例示する。現在時制で示される実施例は、特性において仮説的であるが、それにも拘らず本発明の範囲内にある実施形態を例示するものである。
セメント#11およびフライアッシュ 8z1を使用して、他のモルタル組成物(すなわち、60:40ブレンドおよび70:30ブレンド)を製造した。さらに、「セメント#13」として特定される他の分級セメント材料、および「フライアッシュ 7G」として特定される他の分級フライアッシュを使用して、モルタル組成物を製造した。セメント#13は、セメント#11と同一の施設で分級した。セメント#11、セメント#13および対照セメントの粒度分布を、その分級施設で、Beckman社クールターLS 13 320X線回折分析装置を使用して測定した。これらの粒度分布を、以下の表3に示している。
