You may not think that concrete can ever fail. This might be a little surprising to you because concrete is one of the strongest materials we have.
Concrete is made of a mixture of Portland cement (10-15%), water (15-20%) and sand (65-75%). This material can be easily formed by adding aggregates, such as gravel (10-30%) and sand (45-70%).
Concrete has excellent compressive strength and Concrete company tensile strength. When concrete hardens, its strength is greatly increased. The addition of aggregates (or small pieces of crushed stone) increases the strength of the cement paste.
When water evaporates from concrete, the aggregate bonds to itself and forms a hard, strong material. Once concrete is poured, it cures or hardens within 24-48 hours. You can add a variety of additives to concrete that will change its appearance, color or composition. Examples include steel fibers, pigments, polymers, etc.
