What is Concrete Durability?

February 19, 2017 TeamCivil Concrete, Durability, Properties

Concrete structures are designed to achieve a certain service life. For instance, bridges are designed to achieve a 100 – 120 years of service. However, concrete life can be compromised or ended before the specified life.

February 19, 2017 TeamCivil Concrete, Materials

The word “cement” itself is a general word means “a glue” while “portland cement” is a more specific type of glue that is used in the civil engineering construction. The most important feature of the portland

Calculation of Loads and Pressures on Concrete Formwork

February 18, 2017 TeamCivil Construction

In concrete construction, forms are extremely important as they mold the concrete to the required size and shape. When it comes to construction, forms have to be designed properly to provide safe support to loads

Workability of Concrete and the Factors Influencing its Value

February 14, 2017 TeamCivil Concrete, Properties

The term “workability of concrete” refers to the ease with which freshly mixed concrete is placed, consolidated and finished without segregation. According to the ASTM, workability is defined as “the property that determine the effort required to

Concrete Shrinkage: Definition, Factors, and Damage

February 13, 2017 TeamCivil Durability

Concrete is the result of mixing cement, water and aggregates (fine and coarse). Cement reacts with water and constitutes the paste (glue) which covers and binds the aggregates. One of the properties of concrete that of

Determination of Soil Moisture Content

February 12, 2017 TeamCivil Geotechnical, Soil Tests

Moisture content measurement is mainly used to perform weight-volume calculations in soils. Also, moisture content is a measure of the shrink-swell and strength characteristics of cohesive soils. Test applied: ASTM D2216: Standard Test Method for Laboratory Determination of
