Study Notes
Properties of Concrete
- Good-quality concrete has many advantages, including being economical when ingredients are readily available.
- Long life and relatively low maintenance requirements of concrete increase its economic benefits.
- Concrete is resistant to rot, corrosion, and decay, making it a durable building material.
- Concrete can be molded or cast into almost any desired shape, making it a versatile material.
- Concrete is non-combustible, fire-safe, and able to withstand high temperatures.
- It is resistant to wind, water, rodents, and insects, making it ideal for building storm shelters.
- Building of molds and casting can occur on the work-site, reducing costs.
Strength of Concrete
- High compressive strength is a key property of concrete.
- Resistance to weathering, impact, and abrasion are additional benefits of concrete.
- Low tensile strength is a limitation of concrete, but can be overcome with steel reinforcement.
