AN APPROACH TO OPTIMIZING MIX DESIGN FOR PROPERTIES OF HIGH-PERFORMANCE CONCRETE

Open publisher page 7 citations

Abstract

This paper describes how laboratory and in situ test results revealed that the densified mixture design algorithm (DMDA) can be used to produce high-performance concrete (HPC) of good durability and high workability. The water-to-solid (W/S) weight ratio is known to have significant influence on the volume stability of concrete. This paper discusses strength of f?c>56 MPa, slumps of 230-270 mm, effect of the W/S ratio on the development of strength and durability of HPC at both fresh and hardened states. In addition to the water-to-cement (W/C) ratio and water-to-binder (W/B) ratio, the W/S ratio also has a significant effect on the performance of concrete. The utilization of fly ash and slag has been proven beneficial to the rheology of HPC in enhancing its strength development and durability.
