It is a vitreous, lightweight, foam-containing material obtained by adding carbonate or the like as a blowing agent to fine powder of waste glass from automobiles, etc., and heat-treating it at high temperatures. Its bulk density is relatively small at 0.15 to 0.5 g/cm 3 , and the bubbles it contains are closed cells. Therefore, the foamed glass molded article has good nonflammability,
It has heat insulating properties, weather resistance, and high strength, so it is widely used as an excellent building material.

成させるには、多大の時間と費用を必要とする。 However, recently, when constructing using such materials, it has become necessary to increase the size of the materials in order to reduce the amount of work on site. However, although the foamed glass molded product has good heat insulating properties, it tends to warp or warp or crack during the cooling process after foaming in the heat treatment process, so it is difficult to manufacture large-sized products. is not easy.
Furthermore, even if a technology for integrally molding large foam glass moldings were established, it would take a great deal of time and money to complete the equipment to realize this.
本発明者らは、上記状況に鑑み、鋭意検討を重
