Abstract
Abstract One aspect of this paper is to examine the role of glass powder minerals in creating the pozzolanic compounds with usefulness in replacing traditional ordinary Portland cement and effectiveness toward conserving earth resources. Besides this, the study analyzes the effect of two closely mentioned particle size (GP 75 and GP 63 ) with 0–20% substitution on the behavior of concrete. To validate the blended system serviceability with control, the results are analyzed with the three‐way data presentation. The properties of specimen at fresh and hardening stages are compiled for 7, 28, and 90 days of curing period. The results of the study with respect to control and blended mixes describe that workability is not varied significantly up to 20% inclusion and the pozzolanic activity of GP 63 is higher than that of the GP 75 , as the SAI value observed is 87–117% and 81–108%, respectively. In terms of strength, it is the bunch of compressive, split tensile, and flexural strength behavior demonstrating that up to 20% substitution level the gain in strength is progressive. The static and dynamic modulus of blended mix shows no significant difference at 28 days with control concrete. Moreover, the combination of scanning electron microscopy, energy dispersive X‐ray micrography, and nondestructive mode of testing also features the accountability in this respect.
