Concrete Durability - an overview ScienceDirect Topics

15.5.5.2 Concrete Durability. Concrete durability depends upon the degree of exposure, the concrete grade (or strength) and the cement content. A high density, alkali-resistant concrete will better resist the effects of moisture penetration. Since concrete is a porous material reinforcement bars within the concrete will be subject to possible ...

Durability - Portland Cement Association

A cement resistant to sulfate exposure is helpful. Proper concrete cover over reinforcing steel must be provided, and the water-cementitious ratio should not exceed 0.40. Chloride Resistance and Steel Corrosion: Chlorides present in plain concrete (that which does not contain reinforcing steel) is generally not a durability concern.

2020-2-28  Calcium sulfoaluminate cement (CSAC), first developed in China in the 1970s, has received significant attention because of its expansive (or shrinkage-compensating) and rapid-hardening characteristics, low energy-intensity, and low carbon emissions. The production and hydration of CSAC (containing ye’elimite, belite, calcium sulfate, and minors) have been extensively studied, but aspects

15 Factors Affecting Durability of Concrete - The Constructor

2010-1-26  1. Cement Content. Quantity of cement used in concrete mix will also be a factor affecting durability of concrete. If cement content used is lower than the required, then water cement ratio becomes reduced and workability also reduced. Adding more water to this mix results in formation capillary voids which will make concrete as permeable material.

What Is Durability Of Concrete? Factors Affecting It?

2021-12-1  The durability of concrete will be affected by the shrinkage of concrete. If the cement content is exceeded, it leads to shrinkage happening in concrete. The lower cement content decreases the bondage between the concrete materials, reducing concrete strength. So using the proper amount of cement content is essential.

The durability of concrete depends on the following factors as follows: Water/cement ratio: Higher water/cement ratios are the reason for larger permeability, so for durable concrete using a lower W / C ratio is helpful. Instead for using high W / C ratios to protect strong steel towards corrosion, use low W / C and sufficient cover. Cement ...
