Calculation of Loads and Pressures on Concrete Formwork

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

Types of Concrete Admixtures

TeamCivil Concrete, Properties

Before stating the types of concrete admixtures, let us start first by the definition of “Admixtures”. According to ACI Committee 116, an admixture is ‘a material other than water, aggregates, hydraulic cement, and fiber reinforcement, used

How to Reduce Bleeding in Concrete?

TeamCivil Concrete, Properties

Bleeding is the development of a layer of water at the top or surface of freshly placed concrete. The cause of bleeding is the settlement of solid particles (such as cement and aggregates) and the simultaneous

Workability of Concrete and the Factors Influencing its Value

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

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

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

Geopolymer Concrete

TeamCivil Concrete, Materials

It was estimated that the production of cement which is used for concrete industry increased from about 1.5 billion tons in 1995 to 2.2 billion tons in 2010. The problem is that cement industry is
