项目摘要
Highly durable concrete can use for a long time, and have deterioration resistance. In recently year, durable concrete products which have deterioration resistance have been produced to make water less and dense concrete by progress of air entraining agents. Although, in such cold district as Tohoku, them suffer much damage such as scaling and collapse. Especially, a side ditch caver which has installed a load suffers complex deterioration by freeze-thaw repetition and salt damage by a lot of deicing salt. In this study, produced a ditch caver by using permeable form method, and performed surface layer strength test, freeze-thaw test and scaling test. The permeable form method drains excess water and air bubbles at concrete, and makes the concrete surface dense. The result of those test, increased the surface layer strength, frost damage resistance and scaling resistance. Therefore, permeable form method is effective to produce the highly durable concrete and can use for a long time.
高耐久性混凝土可长期使用,并具有抗劣化能力。近年来,通过引气剂的发展,已经生产出具有抗劣化性的耐久混凝土产品,以使混凝土更少水和更致密。虽然,在这样的寒冷地区,东北,他们遭受了许多破坏,如缩放和崩溃。特别是,已经安装了负载的侧沟挖掘机遭受由冻融重复引起的复杂劣化和由大量除冰盐引起的盐损害。本研究采用透水成型法制作了一种挖沟器,并进行了表层强度试验、冻融试验和缩比试验。透水模板法将混凝土中多余的水和气泡排出,使混凝土表面密实。试验结果表明,提高了表层强度、抗冻性和抗结垢性。因此,透水模板法是生产高耐久性混凝土的有效方法,可长期使用。
