Macro-level Performance Assessment of Concrete: Conventional Approach

The performance of concrete is significantly impacted by its constituents and their composition. As a result, it is expected that the usage of different coarse aggregate, namely, NCA and RCA, will cause the performance of NAC and RAC to vary. The physical and mechanical properties of RCA that are detailed in Chapter 3 are inferior to NCA. Thus, it is also anticipated that concrete’s performance at the macro-level will suffer as a result of aggregate’s weaker qualities. In Chapter 4, a new mix design approach, i.e. PPM, is suggested and discussed in order to address this problem. The performance of PPM mix-designed concrete in the fresh and hardened stages is covered in this chapter, along with a comparison to mixes made using the standard IS: 10262 (2009) method. The performance of four various concrete mixes in both the fresh and hardened stages is described in the following sections.
