Method for predicting high-temperature burst risk of ultra-high performance concrete

The invention discloses an ultra-high performance concrete high-temperature burst risk prediction method which comprises the following steps: measuring the tensile strength, compressive strength, elastic modulus and water absorption porosity of ultra-high performance concrete, and calculating a burst factor of the ultra-high performance concrete according to the tensile strength, compressive strength and elastic modulus; determining the length, the diameter, the melting point, the density and the mixing amount of organic fibers mixed in the ultra-high performance concrete; calculating a high-temperature bursting risk coefficient eta of the ultra-high performance concrete, and judging whether the ultra-high performance concrete has a high-temperature bursting risk or not according to the calculated risk coefficient eta: when eta is greater than 1, judging that the ultra-high performance concrete has no high-temperature bursting risk; when eta is equal to 1, determining that the ultra-high ...
