Effect of Accelerated Curing on Abrasion of High Volume Supplementary Cementitious Material Self Consolidating Concrete
Sustainability of precast/prestressed concrete plant can be promoted by using supplementary cementitious material and that significantly reduces the embodied energy of precast/prestressed concrete products. Usually, up to 25% of the cement can be replaced with supplementary cementitious materials (SCM). Increasing the level of replacement to exceed 25% is considered to be High-Volume SCM. Appropriate testing should be conducted to ensure desired performance of the concrete. This context reports the results of an experimental investigation of effect of accelerated curing on abrasion resistance of High Volume Supplementary Cementitious Material - Self Consolidating Concrete (HVSCM-SCC). Different mixes proportion with supplementary cementitious materials such as Fly Ash, Micro Silica, and lime (Up to 75% of cement replacement) were tested. Rheological properties of the HVSCM-SCC were measured. Mechanical properties at different ages 1, 3, 7, 28, 56, and 90 days were monitored. To investigate the abrasion resistance, 12 x 12 x 3.5 in specimens at age of 28, 56, and 90 days were conducted. The results of abrasion resistance of HVSCM-SCC were compared to the same mixes cured in the moist room. The result showed that the accelerated curing has a significant influence on abrasion resistance of concrete at early ages.
