01/01/2021  In case of the high-strength parent concrete, the mechanical properties of the resultant RAC were superior as compared to RAC made with normal- and medium-strength parent concrete. The results of this investigation demonstrate that the high-strength parent concrete should be preferred for the production of recycled aggregate concrete of lower grade strength. 4.

Top 15 Factors Affecting Strength of Concrete

13/09/2017  The factors affecting the strength of concrete are mentioned below. These factors can be either dependent or independent of each other when comes to the concrete strength. Most of the factors are interrelated in certain means. The primary factor that has a higher influence on the strength of the concrete is the mix design factors. Each of them is mentioned and explained in detail one by one.
