Compressive Strength Test of Concrete

March 6, 2017 TeamCivil Concrete, Tests

This test is considered as the most popular test performed on concrete in construction as it gives a general idea on the all the characteristics of concrete. Based on this test, one can either accept

Reinforced Concrete Quantity and Rate Analysis

March 5, 2017 TeamCivil Construction

In order to perform rate analysis for reinforced concrete, two steps are involved: 1- Estimation of number of labour and equipment, quantity of materials, miscellaneous items required for for a certain quantity of reinforced concrete. 2- Determination of structural

Effect of Water-to-cement Ratio on Concrete

March 4, 2017 TeamCivil Concrete, Durability

The concept of water-to-cement ratio (w/c) of concrete is a universally fundamental concept and is considered as the oldest law in the concrete technology. The water/cement ratio influences the durability properties of concrete in a

Practical Considerations for Reinforced Concrete Design

February 26, 2017 TeamCivil Concrete Design, Construction, Structural

It is known that in RC construction, simplicity and repetitiveness are the keys to economy. For beam and girder framing schemes with one way slabs, the next points should be taken into account: 1. For one-way load transfer

Structural Damage Caused By Reinforcement Corrosion

February 22, 2017 TeamCivil Concrete, Durability

Corrosion of steel in concrete may cause structural damage and early failure of Reinforced Concrete structures. Besides the volume increase and cover spalling due to corrosion (Figure 1), it negatively influences, the flexural, shear, and

Corrosion Damage Stages During Service Life

February 22, 2017 TeamCivil Concrete, Durability

In 1982, Tuutti proposed that deterioration due to steel reinforcement corrosion can be represented by a two stage model (Figure 1). The first stage is associated with corrosion initiation, in which detrimental substances (such as

Permeability of Concrete

February 22, 2017 TeamCivil Concrete, Durability

In general, permeability is defined as “the property that controls the rate of flow of a fluid into the porous solid”. Regarding concrete, the difficulty of the migration of the liquid and gas through the concrete
