Research on the crack resistance ability of hybrid fiber reinforced concrete

A forced mixer and the secondary material mixing technique were used to ensure even scattering of fibers in the concrete mixtures. Specimens and the test cubes were compacted by using a vibrating table with the square of 1 m × 1 m. After 24 hours’ standing, the mold of the specimen was removed and taken to the standard curing room. With 28 days’ curing, the tests were performed.
