| Abstract: | The paper introduces the replacement of deformation joints by post poured joints for the construction of continuous concrete base slab of an over length structure, as well as cracks control problem on the basis of Xianffeng building project construction. By means of cracking causes analysis of concrete and a series of technical measures, such as optimal adoption of cement variety, concrete gradation and admixture, scientifical arrangement of location of post poured joints, rational organization of construction technology, pouring sequence and curing method, the continuous concrete base slab above mentioned was prevented from any harmful structural cracks, temperature and shrinkage cracks successfully. |
