Strength Characteristics of Soil Concrete Using Jeju Volcaniclastic and Construction Techniques
In this study, a series of soil concrete mixtures were tested for the compressive strength according to ratio of aggregate to binder, compaction energy, maximum aggregate size, ratio of silica fume to cement, and ratio of water to binder. The optimum mixing ratio of soil concrete mixtures composed of volcaniclastic, cement, silica fume, concrete polymer and water were analysed. The test results for optimum proportion were as follows ; ①ratio of aggregate to binder was 4 : 1, ②compaction energy level was level 2, ③maximum aggregate size was 13 mm, ④ratio of silica fume to cement was 10%, ⑤ratio of water to binder was 25%. Also, dry type construction techniques were applied using the optimum soil concrete mixture. From the results of this study, the compressive strength of soil concrete and construction techniques were suitable for making eco-friendly soil pavement.
