| Abstract | ||
| To ameliorate shrinkage problems in concrete, the most common route is to cut down the cementitious paste volume. This study proposed and demonstrated the strategy of filling industrial waste powder into the voids among aggregate particles in order to effectively fulfill the target of reduction in cementitious paste volume without air entrapment in concrete. The workability, strength and shrinkage of concrete mixes with 0-12.5% industrial waste powder content to replace cementitious paste at 0.35-0.60 water/cement ratio have been measured through slump, flow, cube strength, prism shrinkage tests. Results disclosed that utilization of industrial waste powder to replace cementitious paste significantly lowered the ultimate shrinkage strain by as high as 58.3% and prolong the shrinkage half-time by as high as 47.1%. In-depth analysis revealed that ultimate shrinkage strain was governed mainly by the cement content whereas shrinkage half-time was governed mainly by the water content. | ||
