Early desiccation cracking of concrete would directly affect the durability of reinforced concrete structure. In order to improve the early desiccation cracking behavior of concrete, the concrete specimens mixed with basalt fibers were prepared. Based on the indoor and outdoor exposure test methods, the effects of short-cut basalt fiber content on early desiccation cracking of concrete and were analyzed by using initial crack time, crack number, maximum crack width and total crack area as evaluation indexes. The test results show that the total crack area of the basalt fiber concrete with a volume fraction of 0.05%, 0.1%, and 0.15% increased by -5.0%, 73.6%, and 86.5% respectively after the outdoor exposure test. The total crack area of reinforced concrete specimens with a volume fraction of 0.1% increased by 63.6% after the outdoor exposure test. The early desiccation cracking behavior of concrete and reinforced concrete could be improved by adding the content of short-cut basalt fiber.
