Abstract
Description
クレイ微粒子を0.0001〜15重量部、含有することを特徴とする。
水6.5Kg,セメント16.2Kg,細骨材48.6Kg、クレイ微粒子であるヘクトライトのフッ素変性品0.0258Kgを混練してフレッシュ状態のモルタル(以下、単にフレッシュモルタルとも言う)を製造した。
水7.1Kg,セメント16.2Kg,細骨材48.6Kg、クレイ微粒子であるヘクトライトのフッ素変性品0.0258Kgを混練してフレッシュモルタルを製造した。
水6.0Kg,セメント16.0Kg,細骨材50.0Kg、クレイ微粒子であるヘクトライトのフッ素変性品、0.04Kgを混練してフレッシュモルタルを製造した。このモルタルは、水の割合が多く、通常は材料分離が発生する配合である。
水8.0Kg,セメント16.0Kg,細骨材50.0Kg、クレイ微粒子であるヘクトライトのフッ素変性品、0.12Kgを混練してフレッシュモルタルを製造した。このモルタルは、水の割合が特に多く、通常はモルタルとしての使用が困難な配合である。
水6.5Kg,セメント16.2Kg,細骨材48.6Kgを混練して、フレッシュモルタルを製造した。
セメント100g、クレイ微粒子5gからなる硬化性無機材料を、水895gと混合して懸濁液を得た。硬化性無機材料懸濁液を40分間静置した後、上澄み液を採取した。採取した上澄み液を乾燥させて質量を計測したところ、9.39gであった。
Y=2.75X − 4.02 (式1)
で、相関係数R2=0.98であった。
硬化性無機材料に含まれるクレイ微粒子を検出するための、より簡易な代替例を以下に示す。
Claims (3)
- セメント100重量部に対して、
骨材を0〜90.0重量部、
