Abstract
【解決手段】水ガラスだけでなくセメント結晶構成要素材料を含まず、コンクリートへの高い浸透拡散性を持ち且つコンクリート躯体内にセメント結晶を形成、促進することを反復継続し、コンクリート躯体全体の恒久的不透水化、高耐久を示現可能な触媒性化合物を1ないし35%含有する。触媒性化合物には、多価カルボン酸のナトリウム塩、またはそれと同等あるいは近似の性質を有する酸のナトリウム塩を用い得る。施工にあたっては、前記セメント結晶形成促進材を、コンクリート表面に散布、噴霧または塗布するだけでよい。コンクリートに対する与湿作業も不要である。
【選択図】なし
Description
(a)2体の上端面に、本発明の水液型セメント結晶形成促進材(フマール酸ナトリウム7%配合)を1体当り1.6mm散布した後、2週間放置し、
(b)他の2体は無処理のままとし、
(a)、(b)の両供試体共に材齢4週で、次のような3種の試験を行った。
Claims (4)
- 水ガラスだけでなくセメント結晶構成要素材料を含まず、コンクリートへの高い浸透拡散性を持ち且つコンクリート躯体内にセメント結晶を形成、促進することを反復継続し、コンクリート躯体全体の恒久的不透水化、高耐久を示現可能な触媒性化合物を1ないし35%含有することを特徴とする水液型セメント結晶形成促進材。
