The In Situ Strength Assessment of Polymer Self Compacting Concrete in Rc Beams
Author(s):
Abstract:
Wide attempts have been performed to quantitative and qualitative control on concrete strength in structures and different methods have been innovated to estimate the in situ concrete compressive strength. On the basis of these methods, it can be divided into two groups consisting non-destructive and semi-destructive methods. To provide a suitable compaction, decrease on segregation and bleeding and facilitating on placement of concrete especially in sections with massive reinforcement, self-compacting concrete has been developed. In the research by Zhu et al. [1] in 2001, self-compacting concrete strength along length of beams and height of columns was investigated using core, pull out and Schmitt hammer tests and the results on uniformity showed similar pattern on variations. Also the results indicated that concrete strength variations along height of columns and length of beams for self-compacting concrete are slightly lower than normal concrete.
