| Summary: | 碩士 === 明新科技大學 === 土木工程與環境資源管理研究所 === 100 === The flow table test is used to determine the rheological characteristics of mortar specimens with various ratios of cement to sediment. The optimal ratio of cement:sediment:water is 1:x:x for 0.4≤x≤1. Compression test is used to verify the strength of mortar specimens. The result shows that the compression strength of mortar specimen is 86 kgf/cm2 after 28 days hardening for a cement mortar mixed with sediment with a ratio of 1 to 0.9. It verifies that the sediment can be used for concrete pavement for a minimum requirement of compression strength of 80 kgf/cm2. The compression strength of mortar specimen with a ratio of 1 to 0.5 after 28 days is 208 kgf/cm2, which can be used for large section of structures with reinforced concrete of strength over 176 kgf/cm2.
