Description: Pasir Kasar, Or Coarse Sand, Is a Type Of Matural Sand With Larger And Rougher Particles Compared To Fine Sand (Pasir Halus). It Is Typically Sourced From Riverbeds, Quarries, Or Mining Sites And Consists Mainly Of Crushed Rock, Quartz, And Silica. With Its Coarse Texture And Higher Strength, Pasir Kasar Is Widely Used In Concrete Production, Foundation Work, And Other Structural Applications Where Strength And Stability Are Crucial. The Rough Surface Of Its Grains Provides Better Interlocking And Bonding With Cement And Aggregates, Making It An Essential Material For Durable Construction.
