Metallic Aggregate In Concrete Floors

Appears on pages(s):
The requirements of metallic aggregate for use in concrete floors are given and good practice in laying floors with such aggregates is described. Methods and apparatus for measuring the resistance to abrasion and to impact are described. The results secured show the superiority of leaner mixes contain-ing aggregate of larger maximum size of metallic aggregate at the surface and of encreasing the thickness of the metallic layer. Comparisons of mechanical floating and tamping are made.
