The use of self-compacting concrete (SCC) has been established; however, novel methods for optimizing and providing suitable workability are still developing. The effect of magnetized water on SCC, by keeping the dosage of superplasticizer constant and reducing the ratio of water-to-cement, was investigated. Results showed a 10% decrease in the amount of water required and a 12% increase in compressive strength. Moreover, the effect of magnetized water on the dosage of superplasticizer in SCC, for making a specific spread diameter (600±10 mm) was studied. Results indicated that use of magnetized water in self-compacting concrete can reduce superplasticizer dosage by up 30%.
