Lightweight Concrete with Expanded Glass BPN

Ordinary river aggregate and a commercial expanded glass aggregate with particles size in the range of 24 mm ( in) were used to prepare mortar samples for testing. Particle size distribution is presented in Figure 1. The aggregate was obtained by mixing 70% by volume of the ordinary aggregate and 30% by volume of the expanded glass.

The role of aggregate in concrete countertop mix designs

Lightweight aggregates, a topic for another discussion, are also used in concrete. Size. Aggregate size and gradation are the most important factors when selecting aggregate. Aggregate can be large or small, from fistsized rocks to fine sand. Aggregates larger than ¼ inch are classified as coarse aggregate, while anything smaller than ¼ inch

Aggregate for Lightweight Concrete The Masterbuilder

GIB is the lightest aggregate having density from 100 Kg/m3250 Kg/m3. This material, white or light gray in color, is about 1/10 the weight of sand or gravel. The specially processed GIB aggregate consists of expanded particles for use in lightweight concrete, fire retardant plaster or insulating concrete in place of sand or gravel.

Aggregate Properties The Concrete Portal

Aggregates that predominantly show size fractions in a limited range of sizes (such as the 20 mm and 10 mm aggregate in Figure 1) are called 'uniformly' graded, while aggregates that show a continuous gradation of size (sand in Figure 1) are called 'well' graded or continuously graded.
