aggregates cannot be overemphasized. The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ-ence the concrete's freshly mixed and hardened proper-ties, mixture proportions, and economy. Fine aggregates (Fig. 5-1) generally consist of natural sand or crushed

Mica flakes, seized in Fine and Coarse grades, is essentially used in Loss Circulation applications during drilling operations. Mika flakes can be used in water-based and oil based mud drillings operations as a mud additive chemical to prevent loss of circulation and seepage. Mica is added in particular to seal-off the loss circulation zones.
