    Concrete is a mixture of cement, sand, pebbles or crushed rock and water, which, when placed in the skeleton of forms and allowed to cure/harden, becomes hard like a stone.

    Major advantage of concrete over traditional wood is that concrete outperforms wood as a construction material, and won’t burden building owners with constant repair and maintenance costs. Versatile, long-lasting and durable, concrete is a cost-effective, sustainable choice for both residential and commercial buildings.

    Main disadvantage would be that it has low strength-to-weight ratio, has less tensile strength and is susceptible to cracking.
