Effects of Blending Materials on the High Strength of Hardened Cement Paste
DSP technique was applied to improve the high strength characteristics of hardened cement paste using pozzolan materials as blending materials, and pozzolan reactivity was investigated. Pozzolanic materials such as diatomaceous earth, fly ash and hydrated silica were used as blending material. And also superplasticizer was added to cement for molding the specimens. After curing for 60 days, the specimens substituted with 10 and 15 wt% of diatomaceous earth showed better strength characteristics than the specimen with fly ash. The specimen substituted 7 wt.% of hydrated silica exhibited excellent strength with above 800 kg/$textrm{cm}^2$.
