The Aggregates(fine + coarse) generally occupy 60% to 75% of the concrete volume or 70% to 85% by mass and strongly influence the concrete's freshly mixed and hardened properties, mixture proportions, and economy. All Aggregates pass IS 4.75 mm sieve is classified as fine Aggregates.

When hand sieving mixtures of coarse and fine aggregate, the material should be separated into two sizes on the 4.75 mm sieve. Any material passing the 4.75 mm sieve from the coarse sieve analysis must be added to the original pass 4.75 mm fraction and thoroughly blended before splitting off the fine aggregate sample for testing. This step is ...

It is similar in nature to the coarse aggregate specific gravity test. Figure 1: Fine aggregate specific gravity sample and pycnometer. The fine aggregate specific gravity test measures fine aggregate weight under three different sample conditions: Oven-dry (no water in sample). Saturated surface dry (water fills the aggregate pores).

The 28-day compressive strength of polystyrene concrete increased from 5.6 MPa to 11.9 MPa when the w/c decreased from 0.60 to 0.35. The compressive strength of LWC was shown to be more sensitive ...

Recycled waste glasses were used as coarse and fine aggregates replacement in concrete. Coarse aggregates were replaced with Green Bottles coarse aggregates at third, half, two thirds, and ...

The flow time of mix 1 (44% fine to 56% coarse) was 8.2 sec, 8.5 sec for mix 2 (47% fine to 53% coarse), and 11 sec for mix 3 (50% fine to 50% coarse). It is also noticed in Table 5 that the relative viscosity (t 50 ) is …

All in Aggregate. It is the aggregate composed of both fine aggregate and coarse aggregate. According to size All-in-aggregate is described as all-in-aggregates of its nominal size, i.e. 40mm, 20mm etc. For example, all in aggregate of nominal size of 20mm means an aggregate most of which passes through 20 mm IS sieve and contains …
