Behavior of self-compacting concrete incorporating mineral admixture

Abstract

The objective of this paper is to investigate the effect that mineral admixtures, different SPs, and different VMAs have on the fresh qualities of SCMs. In this specific instance, the four mineral admixtures that are used are fly ash, limestone powder, brick powder, and kaolinite. Pozzolanic or non-pozzolanic are two possible classifications for these admixtures. One of the SPs had a base consisting of melamine formaldehyde, while the other three included polycarboxylates as their primary component of their bases. On the other hand, the VMAs were an aqueous dispersion of microscopic admixtures based on silica, and they also included a high molecular weight admixture based on hydroxylated polymer. It is possible to make a variety of concrete mixes, each of which has its own unique slump flow, V-funnel, and setting characteristics, which are evaluated in the same way as the fresh properties. At 7, 14, and 28 days of age, respectively, the material is evaluated for its density, ultrasonic pulse velocity, and strength. These are the hardened attributes that are taken into account.
