Abstract |
Waste lime is place of business general waste that is happened by product fertilizer and chemical factory etc. This paper is to investigate the properties of cement composites containing high volume waste lime and fly ash to grope the practical use way of waste lime as the construction material. Therefore, consider CaO and CaCl2 that much amounts were contained to waste lime in this research by main factor that influence in pozzolan reaction of fly ash and controlled mix. Experiment factors of this research was the ratio of waste lime and fly ash, the addition amount of cement and aggregate-binder ratio, water-binder ratio, curing temperature. In the results of test, the compressive strength of cement hardness is decreased according as increased the addition amount of waste lime, but the addition amount of waste lime appeared comparatively high by 200kgf/cm2(age 3day) and 343kgf/cm2(age 90day) to that is 40%. Much included Ca2+ in waste lime are contributing in pozzolan reaction of fly ash. Also, It is found that pozzolan reaction of fly ash activated by much included CaCl2 in waste lime. |
