Study Notes
Concrete Basics
- The word 'concrete' originates from the Latin word 'concretus', meaning "to grow together".
- The primary binder of concrete is cement.
Composition and Properties
- Cement holds together the aggregates in concrete.
- The properties of concrete, such as compressive strength and permeability, are influenced by the water-to-cement ratio.
- The water-to-cement ratio is one of the most important factors influencing concrete properties, including compressive strength, permeability, and diffusivity.
- The estimated range of cement content in mass concrete is not clearly defined but varies in different mixes.
Global Consumption and Production
- The estimated annual consumption of concrete worldwide is around 20 billion tons per year.
- In terms of worldwide production, concrete production exceeds that of steel.
Advantages and Limitations
- One of the reasons for the popularity of concrete as a construction material is its high strength and durability.
- One advantage of concrete is its thermal mass, which allows it to absorb and release heat, making it energy-efficient.
- In terms of energy efficiency, the production of concrete compares favorably to that of steel.
- A limitation of concrete is its susceptibility to cracking, which can lead to reduced strength and durability.
- The workability of fresh concrete allows it to be poured into various formworks to form different shapes and sizes right on a construction site.
