New and Mechanical Properties of Self-Compacting Microstructure of Lightweight Total Cement with and without Filaments - K Govardhan Reddy, Sagar Darur (Mathematical Statistician and Engineering Applications, 2021)
The rising volume of waste tires over the past few years has made them a major environmental concern. Cement can be repurposed in creative ways. Piece tires are broken down into small particles and added to lightweight total cement to make self-compacting elastic lightweight total cement (SCRLC). A lot of testing has been done to see how elastic particles affect the properties of SCRLC and the mortar that goes with it. The plastic thickness and yield pressure both rise when elastic particles are used in mortar. An increase in SCRLC’s elastic particle replacement percentage results in a decrease in flowability, filling limit, and passing capacity. There was a close correlation between the SCRLC droop stream, shear pressure, SCRLC isolation percentage, and plastic thickness of the mortar glues in question. To ensure that elastic lightweight total cement can pack on its own, the plastic thickness should be limited to 231.7 Pa with a lower cutoff of 3.72 Pa S. When the elastic particle replacement fraction rises, both SCRLC and the matching mortar experience a decrease in their compressive strengths. For elastic particles, the 28-day compressive strength of SCRLC may meet the requirements for light weight total significant improvements up to a half swap percentage.
