Various fibers are incorporated in concrete to control cracking or improve abrasion and impression resistance.
Concrete dust introduced by building demolition and natural disasters is usually a important supply of perilous air air pollution. Concrete is actually a contributor on the city warmth island effect, even though significantly less so than asphalt.
