Abstract

ABSTRACT:

Nanomaterials are increasingly noticed and applied in many fields to fabricate new materials with new functions due to their unique physical and chemical properties. If Nano SiO2 is integrated with a cement-based building material, the new material could possess a number of outstanding properties. The article presents the research results showing that the addition of Nano SiO2 to the UHPC mixture brings very good results. This promotes research and application of Nano SiO2 into UHPC production technology using available materials and suitable for construction conditions in Vietnam.
