Abstract:
Investigates various properties of silica fume concrete, such as slump, air content, compressive strength, flexural strength, permeability, and permeable void volume. The effect of silica fume replacement ratio of cement is described. Also, the effects of aggregate content and graduation, water-binder (cement + silica fume), and superplasticizer dosage rate are discussed. The results are important in drawing parallels of plain and silica fume concrete mix design procedures. In this experimental investigation, silica fume-binder ratio ranges from 0 to 0.40, water-binder ratio ranges from 0.41 to 0.47, aggregate-binder ratio ranges from 1.0 to 4.0, and superplasticizer-binder ratio ranges from 0.01 to 0.05.
