Analysis on Causes about Concrete Slab Cracks of Residential Projects and Research on Control Measures

Abstract:

At present, China lacks theoretical guiding and research on the concrete floor cracks control of residential projects, and there is no advanced experience of other countries for reference on some aspects. The concrete slab cracks of residential projects has become the focus of public attention, the hot spot of complaints and the difficult point of government business. To avoid the cracks has become a big problem and an important content in improving the residential projects’ quality, which demands prompt solution. This paper analyzes the causes of cracks from construction point, and puts forward some proposals from four aspects including formwork engineering, reinforced bar engineering, concrete engineering and aspect of construction management. This paper advances some immediate countermeasures, makes some moderate extensions on the strategic development of architectural technology and designs the solution orientation of the long-term countermeasures. These concrete solutions strive to be conveniently carried out, meanwhile give consideration to the economic legitimacy.
