A comparative study of compressive strength and split tensile strength on effect of size of coarse aggregate in hybrid fiber reinforced concrete with different grades


K Chanakya Srinivas, J Usha Kranthi

Concrete is one of the main materials of the structure and is widely used in the world. While advanced technology for concrete has recently focused on developing various properties of concrete by adding different materials. The voids in concrete are also one of the important factors in the rationalization of concrete strength. By reducing the porosity of concrete and improving the uniformity of concrete, it is one of the effective means to improve the strength of concrete. Coarse aggregate usually accounts for more than one third of the volume of concrete; studies have shown that coarse aggregate changes can change the strength and fracture properties of concrete. In order to predict the behavior of concrete under normal loads, it is necessary to understand the effects of aggregate type, aggregate size and polymer content. This understanding can only be achieved through extensive testing and observation. Polymer grading is an important part of concrete mixing, resulting in compressive strength. Experiments were conducted to determine the effect of aggregate size on the compressive strength of concrete. Adding the fiber to the concrete rather than increasing the tensile strength itself, but mainly controlling the crack, and changing the behavior of the cracked material by bridging the fiber across the crack. With a single type of fiber reinforced concrete, the desired performance can be increased to a limited level. In this study, the effects of different sizes of coarse aggregate on the properties of concrete, such as the workability of concrete in M30, M40 and M50 concrete, compressive strength, tensile strength and splitting tensile test and fine uniformity of UPV, were studied. For the standard combination to replace 12.5mm aggregate to 20mm aggregate to find the best mixture content. So, for the best mix of alternatives, we will study the effect of 10mm aggregates to find the best combination. In both cases, the replacement starts at 0%, and each mix increases by 5% to find the best combination. Polypropylene fibers are added (PPF) to the best mix and the results are compared with normal mix.
