INVESTIGATION OF THE WORKABILITY AND MECHANICAL QUALITIES OF HIGH-STRENGTH LWSCC
Romus Anal1, Dr. Sanjeev Singh2
Abstract:
Nan-Su has developed a new type of self-compacting concrete that is both lightweight and highly durable (HLSCC). This study examines the mechanical properties of HLSCC in both its fresh and hardened states. The JSCE second-class grading standard was used to test and assess HLSCC's flowability, segregation resistance, and fresh concrete filling ability. After 28 days of curing, researchers examined HLSCC's compressive strength, splitting tensile strength, elastic moduli, and density. Second-class standard of the JSCE states that the lightweight aggregate mix ratio of the HLSCC must not exceed 75% for LC and 50% for new. Compressive strength of HLSCC after 28 days was more than 40 MPa in all but one mix, whereas structural efficiency increased in direct proportion to mix density.
