Abstract
Abstract A light-weighted vibration-absorbing and fire-resisting floor for a vehicle comprising three layers; a first layer comprising an epoxy or urethane synthetic resin elastic material, a second layer wherein an aggregate formed by baking fireclay mineral of kaolinite and expansible mineral is coated with the epoxy or urethane elastic synthetic resin, and a third layer composed of a fire-resisting resin mortar, and three such layers being integrally coated one over another.
