Aggregates - Cement

In general, if the water-cement ratio is chosen correctly, a wide range in grading can be used without a major effect on strength. When gap-graded aggregate are specified, certain particle sizes of aggregate are omitted from the size continuum. Gap-graded aggregate are used to obtain uniform textures in exposed aggregate concrete.

Feldspar and mica. Key minerals for fine aggregate

1984-12-1  Research on the aggregate-concrete interaction has proved feldspar and mica to be key minerals for concrete quality. Feldspars are predominant minerals in most Norwegian aggregates. A relation has been found between the strength of cement mortars and the type and condition of the feldspars present. Especially, the degree of feldspar alteration (saussurite, sericite) appears to be a
