Abstract

Novel cellulose based admixture (NCBA) grades were used to enhance medium strength SCC (w/c 0.60) robustness. Comparison was made with the use of limestone powder and a commercial stabilizer. Robustness was evaluated by measuring the effect of water content variation on slump-flow, viscosity by t500-time, sieve segregation and water bleeding. Hardened concrete segregation and strength was also evaluated. Robustness assessment was based on selected limiting values for both workability and stability properties. Novel cellulose based admixture was an effective way in SCC robustness enhancement. Robustness evaluation was possible by common SCC testing.
