HYDRAULIC COMPOSITION AND HEAT RESISTANT STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a hydraulic composition excellent in heat resistance, in the case the peripheral temperature periodically repeats high temperature and low temperature (ordinary temperature), and also, the conditions occur over a long period, in which deterioration in explosive fracture and strength reduction are hard to occur.SOLUTION: Provided is a hydraulic composition including: a fine aggregate made of portland cement, fly ash and igneous rock; a coarse aggregate made of igneous rock; polypropylene fiber; water; and a water-reducing agent. Basalt or andesite is preferably used as each igneous rock composing the fine aggregate and the coarse aggregate.SELECTED DRAWING: None
