Abstract
In the present research, the morphological and the textural characteristics of a selected group of amorphous nano-silica particles used in concrete were studied. To conduct a detailed characterization of the main properties of micro- and nano-silica, seven selected silica samples produced by different methods were studied thoroughly. The resultant characteristics such as shape, particles size, specific surface area and density, and pores sizes and distribution were related and compared. Finally, the effects of the nano-silica characteristics in the slump-flow diameter and mechanical properties of standard mortars are discussed. In general, the main characteristics of the nano-silica samples and their effect in the workability depend on the origin or production route
