Abstract
At present, conventional concrete has such a image as “heavy, hard, cold”, and has many problems about durability and thermal insulation. And the shortage of natural aggregates has become a serious problem. Thereupon, the authors have developed a special lightweight concrete (MLC) by using formed polystyrene beads with a diameter of less than 1.5mm as an aggregate having no water absorbability. MLC with a low water-binder ratio is an excellent lightweight concrete having excellent properties of durability and thermal insulation. This paper reports the performance of this special lightweight concrete.
