Why is concrete not sustainable?

The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas. Concrete causes damage to the most fertile layer of the earth, the topsoil. Concrete is used to create hard surfaces which contribute to surface runoff that may cause soil erosion, water pollution and flooding.

Does salt water damage concrete?

The answer is yes, salt does indirectly damage your concrete driveways, patios and sidewalks. Bumps and potholes don't just appear due to regular wear and tear – salt damages concrete over time by causing corrosion to occur under the surface, leading to discolored, cracked and crumbling concrete.

Is there an alternative to concrete?

Another popular concrete alternative is ash concrete or ashcrete. This material combines fly ash from coal combustion with lime and water to produce a durable structure. Ashcrete is sustainable because it repurposes coal waste and reduces the energy-intensive process of typical concrete production.

Is concrete harmful to fish?

Why is concrete/cement toxic to fish? Lime is a major component of cement and concrete. It dissolves easily in water (water soluble) and drastically changes the pH of water increasing the alkalinity (pH 11-13), which causes burns (just like an acid burn) on fish and kills fish and other aquatic life.
