Strengths than larger sized coarse aggregates. Cook observed that the difference in compressive strengths due to aggregate size is increasingly larger with a decreasing water-to-cement ratio and increasing test age. The smaller sized coarse aggregate also increases the flexural strength of the concrete.

Seasoning of stone :

Generally, the action of having various changes in different seasons on the stone which are drying and wetting of stone which gradually forms the crack in stones which leads to the action of weathering action and forms inorganic small size materials is called seasoning of stone.

Seasoning refers to both drying and wetting cycles on one hand, and airing of stone, on the other hand. Dehydration during seasoning is more or less an irreversible process. Thus seasoning applied mainly to soft limestone; hard limestone seems to less affected by it. Stones have natural moisture, known as quarry sap. This quarry sap renders the stone blocks comparatively soft and makes them easy for working. Immediately after quarrying, a stone is soft and is easy to work with it so sized and primarily dressed, but polishing requires a fully seasoned and hardened stone.
