Abstract：
The concrete floor of a factory plant covers an area of 82 000 m2 and improper construction frequently causes many quality problems, such as local settlement and deformation at floor joint, cracks on floor, crusting and sand streak on floor surface, over limit of overall deflection of elevation and planeness, etc. Various quality measures are adopted, such as base construction, formwork division design optimization and treatment of division joint, to successfully satisfy relevant acceptance standards and realize favorable construction effects.
