Abstract: A systematic experimental study on the compressive strength in different curing system, shrinkage, and penetration resistance of ultra-high performance concrete (UHPC) mixed with coarse aggregate in different ratios is conducted. The experimental research can draw the following conclusions: The amount of gravel has no discernable effect on the early-age compressive strength of UHPC in the 90°water curing and autoclaved curing; while as the amount of gravel increases in lower temperature hot water or standard curing, the strength of specimens decreases firstly and increases later, while the shrinkage gets the tendency to the contrary; when the gravel content (G/C ) takes 0.8, there is a largest reduction in its strength, drying shrinkage and the self-shrinkage; all experimental group have excellent impermeability,
it is not easy for moisture to penetrate into the specimen in the method of ordinary concrete seepage test.
