Temperature Control and Crack Prevention of High-Performance Concrete Pier in San Yang Gang Tide Gate

Abstract:

San Yang Gang tidal sluice gate is easily to produce temperature crack at early age because of the use of pump hydrotechnic high performance concrete in the constructing process. Based on the analysis of parameters of three-dimensional temperature field and temperature stress field, comprehensive measures which are consist of lower inside temperature through cooling water pipes , keep the outer surface moist, increase temperature distribution bars, reduce pumping concrete slump and mixing polypropylene fiber were proposed. These comprehensive measures have solved the problem of temperature control and crack prevention successfully.
