概要:
金沢大学理工研究域環境デザイン学系<br />he amount of waste concrete from demolished old buildings and pavements has increased in the last 10 years. This has brought about the disposal waste concrete problem in urban areas. Such waste concrete is hard to deal with properly and thus, it is important to recycle it as an aggregate for concrete from the view points of shortage of aggregate from river, energy and resouces saving as well as environmental preservation. The objective of this paper was to investigate the compressive, tensile and flexural strengths, drying shrinkage and durability against freezing and thawing cycles of the recycling concretes with the aggregates obtained by crushing old concrete buildings and concrete pavements. The main results obtained in this study are summarized as follows. (1) The physical properties of the aggregate produced from a concrete pavement are more favorable as an aggregate for concrete than those from a demolished concrete building. (2) The compressive, tensile and flexural strengths of the recycling concrete from a concrete pavement are greater than those of the recycling concrete from a concrete building. (3) The drying shrinkage of the recycling concrete is greater than the natural aggregate concrete. The recycling concrete made with the aggregate from a concrete building shows a greater shrinkage than that made with the aggregate from a concrete pavement. (4) The resistance of the recycling concrete from a concrete pavement against freezing and thawing cycles is better than that of the recycling concrete from a concrete building. The resistance of the recycling concrete made with a concrete pavement is increased by adding an AE admixture, being somewhat inferior to that of the natural aggregate concrete. 続きを見る
