Methods of Crack Repair in Concrete (1)

Methods of Crack Repair in Concrete (1) Following the evaluation of the cracked structure, a suitable repair procedure can be selected. Successful repair procedures take into account the cause(s) of the cracking. For example, if

What are Supplementary Cementing Materials (SCMs)

TeamCivil Concrete, Materials

The term supplementary cementing materials (SCMs) -sometimes called “mineral admixtures”- refers to a broad range of materials that are widely used in concrete in addition to portland cement. An SCM may be defined as “a material

Non-Destructive Testing of Concrete (NDT)

TeamCivil Concrete, Tests

In this article “Non-Destructive Testing of Concrete” brief description is given for methods used to assess concrete strength and durability without damage. Non destructive test is a method of testing existing concrete structures to assess

Structural Forces

TeamCivil Analysis, Structural

Structural Forces A structural system is acted upon by forces. Under the influence of these forces, the entire structure is assumed to be in a state of static equilibrium and, as a consequence, each component

Cement Setting and False Set

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

Structural Elements and Systems

TeamCivil Analysis

Structural Elements and Systems: All structural systems are composed of elements. The following are considered to be the primary elements in a structure: 1- Ties: those members that are subjected to axial tension forces only. Load

Basic Principles of Structural Analysis

TeamCivil Analysis

Basic Principles of Structural Analysis: Structural engineering involves an extensive variety of structural systems to deal with such as buildings, bridges, sports stadiums, radio and television towers, arches, storage tanks, aircraft and space structures, concrete pavements, etc. These

Splitting Tensile Strength of Concrete

TeamCivil Concrete, Tests

One of the important properties of concrete is “tensile strength” as structural loads make concrete vulnerable to tensile cracking. Tensile strength of concrete is much lower than its compressive strength (that’s why steel is used
