| Abstract |
The purpose of this paper is the investigation of field application by comparing effect of compressive strength with vibrating and curing factor, when the lightweight concrete with EPS beads that has light weight and economic property is applied in the field. So we made an experiment on the above two factors and the results were as follows. For the effect of vibrating, as segregation rates were higher the compressive strengths were decreased, so the lightweight concrete with EPS beads didn't need vibrating or had short vibrating time or need to use vibrator with lower vibrating frequency. For the effect of curing condition, when the lightweight concretes with EPS beads were deposited in the field, It was supposed that the batches for structural use and batches of EPS substitution rate 50, 60% for insulation layer on the slab need moisture curing but the batches of EPS substitution rate 70, 80% for insulation layer made no difference though they were leaved in the air |
