Recycled Concrete Aggregate

In a constantly evolving society there stems a need to develop and improve the current infrastructure. In order to build new infrastructure, building materials such as concrete will be needed. The raw materials needed for

Equations of Static Equilibrium

TeamCivil Analysis

Equations of Static Equilibrium Equations of Static Equilibrium: Consider a case where a book is lying on a frictionless table surface. Now, if we apply a force F1 horizontally as shown in the Fig.1(a), then

Self-compacting Concrete: Fresh Properties

TeamCivil Concrete, Materials, Types

Self-compacting Concrete: Fresh Properties Self-compacting concrete has specific fresh state properties which conventional concrete does not have. Fresh concrete properties of SCC are obviously related to its property of self-compactability. Self-compactability in mechanism terms is

Concrete Repair and Maintenance Steps

TeamCivil Repair

Concrete repairs have occurred on Reclamation projects since the first concrete was placed in 1903. Unfortunately, even though the best available knowledge and materials were used, many repair failures have occurred during the 112 years

Standard Proctor Compaction Test

TeamCivil Geotechnical, Soil Tests

In this article named “Standard Proctor Compaction Test”, the details and procedures of proctor test are described. Introduction For construction of highways, airports, and other structures, it is often necessary to compact soil to improve

Variation of Wind Velocity with Height

TeamCivil Analysis, Concrete Design, Structural

In this article named “Variation of Wind Velocity with Height”, how wind speed change as a function of structure height is discussed. The viscosity of air reduces its velocity adjacent to the earth’s surface to

How to Prepare Cube Samples from Fresh Concrete?

TeamCivil Concrete, Tests

Most standards have laid down the acceptance criteria of quality concrete. In all the cases, the 28-days compressive strength shall alone be the criterion for acceptance or rejection of the concrete. 7 days compressive strength of

Concrete Admixtures

TeamCivil Concrete, Materials

Nowadays concrete is being used for various purposes to make it suitable in different conditions. In these conditions ordinary concrete may fail to exhibit the required quality performance such as durability, strength, workability and finishing quality of concrete.
