摘要

The Ca-based solidification material has neutral character for pH and natural color like soils, so that it is paid attention to as a new material instead of cement in civil engineering field. In a previous research, we showed that compression strength of the concrete using this material and compression strength of AE concrete has equivalent strength under same mixture condition, so that concrete using this material will be effective material on strength as a new civil engineering material. In addition, the behavior under compression loading for concrete using this material showed tendency similar to cement concrete because its behavior showed non-linear behavior. Therefore, this research furthermore investigated on characteristics of compressive strength for concrete using Ca-based solidification material through compressive strength test. In particular, this investigation focused on curing method and curing period to consider effects of wetting and drying and long-term strength. Based on the results of tests, the emphasis was placed on the following: (1) The strength in natural curing is larger than the strength in water curing as for the early-age compressive strength of Ca concrete. (2) The strength in water curing was larger than the strength in natural curing as for after 4weeks compressive strength of Ca concrete. (3) The compressive strength of Ca concrete obtained stable strength when it had curing for 4 weeks.
