Honeycombs in Concrete: Causes and Effects
Concrete is one of the most durable materials for construction in the modern history. Yet, it might be exposed to some conditions that negatively affect its performance due to distress. Concrete quality might get compromised
Read moreFeatures of Sulfuric Acid Attack
Sulfuric Acid Attack Sulfuric acid [H2(SO4)] attack on concrete may be identified by a chemical reaction between the acidic media and cement hydration products, leading to excessive formation of gypsum. Acid attack can occur under

Effect of SCMs on Alkali-Silica-Reaction Mitigation 1- Fly Ash the three characteristics of fly ash that determine its efficiency in preventing ASR are fineness, mineralogy, and chemistry. In general, the finer the fly ash, the
Read moreReasons of Concrete Spalling
Concrete Spalling Currently, there are two mechanisms concerning the occurrence of spalling: 1- the pore pressure build up causes spalling in the cement matrix and 2- thermal and mechanical stresses. In 1997, Anderberg gave an account

Corrosion of Embedded Metals in Concrete Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration in concrete. When steel corrodes, the resulting rust occupies a greater volume than the steel.

Carbonation is the term used to describe the effect of carbon dioxide on a material. The phenomenon rarely leads to structural problems but carbonation-induced corrosion can lead to unsightly spalling on structures. The repair costs,

For concrete structures in chloride-containing environments, the ingress of chlorides can take place in different ways. Through uncracked concrete, the ingress mainly takes place by capillary absorption and diffusion. When a relatively dry concrete is
