초록

The purpose of this study is to evaluate the compressive strength properties of hardening using the unrefined fly-ash and waste lime and to offer basic data to someone for recycling waste lime Waste limes are tested that specific gravity and pH value and observed microstructure of particle with SEM. The compressive strengths of Wast lime hardening which is mixed with regular ratio according to each admixture are measured. In the results of test, The pH of wast lime is very high by pH 12.1 and specific gravity is 2.22. Compressive strengths on hardening modified waste lime and fly ash is very effective. The vest compressive strengths is show that CaCl$_2$ existed in waste lime
