- Synopsis
- These specimens consist of precast blocks stacked by applying epoxy resin on end surface of them and prestressing. Prestress is 1 N/mm2. After concrete blocks are piled up, re-bars or prestressing steels as well as mortar grout are inserted into ducts which pass through the blocks.
- This report describes the results of a series of a series of seismic performance experiments for specimens and the characteristic experiments of mortar. The characteristics of mortar are compressive strength, retardation and bleeding.
- As a result, the following matters are confirmed:
- Strengths of precast specimens are the same as that of cast in-place specimen.
- Deformation performances of precast specimens are better than that of cast in-place specimen.
- All of the precast specimens which are inserted the re-bar have as same energy absorption performances as cast in-place specimen.
- The characteristics of this mortar are suitable for field condition.
- This report describes the results of a series of a series of seismic performance experiments for specimens and the characteristic experiments of mortar. The characteristics of mortar are compressive strength, retardation and bleeding.
