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.
