Abstract: The core of a high anticracking concrete is that sulphoaluminate expansion agent and polyacrylic fiber are taken as high anticracking components of the concrete, with which a mutual reinforcement is obtained to improve remarkably the anticracking of the concrete.The new technology has been used for hub building of Guangzhou New Baiyun International Airport, whose use of compensating shrinkage fiber concrete is more than 40?000m +3.A satisfactory result is obtained for prevention anticreacking of superlong giant concrete structure.It is for the first time to use the compensating shrinkage concrete technique for the construction of a large airport domestically.
