Cohesiveness and Consistency of Concrete

March 7, 2021 TeamCivil Concrete, Properties

Concrete Workability Concrete Workability is a property of concrete in its fresh state during mixing. It determines the ease with with casting activities are done including mixing, placing, compacting and finishing. Concrete workability is usually

Flexural Strength of Concrete

January 28, 2019 TeamCivil Concrete, Properties

Flexural Strength Flexural strength is an indirect measure of the tensile strength of concrete. It is a measure of the maximum stress on the tension face of an unreinforced concrete beam or slab at the point

Concrete in Compression (ACI 318)

July 12, 2017 TeamCivil Concrete, Concrete Design, Properties, Structural

Concrete in Compression It is generally accepted that the behavior of a reinforced concrete member under load depends on the stress–strain relationship of the materials, as well as the type of stress to which it is

Concrete in Tension: Tensile Strength of Concrete

July 11, 2017 TeamCivil Concrete, Concrete Design, Properties, Structural

Concrete in Tension: Tensile Strength of Concrete The tensile and compressive strengths of concrete are not proportional, and an increase in compressive strength is accompanied by an appreciably smaller percentage increase in tensile strength. According

Effect of Age on Concrete Strength

May 30, 2017 TeamCivil Concrete, Properties

Effect of Age on Concrete Strength The strength versus gel/space ratio relationship has a general application because the amount of gel present in the cement paste at any time is itself a function of age

Cement Setting and False Set

April 1, 2017 TeamCivil Concrete, Materials, Properties

Cement Setting Setting of Cement, or cement setting, is a term used to describe the stiffening of the cement paste. Setting refers to a change from a fluid to a rigid stage. Although, during setting, the

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.

Types of Concrete Admixtures

February 17, 2017 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
