Types and Causes of Concrete Deterioration

Types and Causes of Concrete Deterioration

concrete, the passive corrosion rate is typically µm per year. Without the passive film, the steel would corrode at rates at least 1,000 times higher (ACI 222 2001). Because of concrete's inherent protection, reinforcing steel does not corrode in the majority of concrete elements and structures. However, corrosion can occur when the passivating layer is destroyed. The destruction of the ...

Bulking of Sand – Cause, Tests and Importance

Bulking of Sand – Cause, Tests and Importance

When concrete proportioning is to be performed, the sand bulking issues is a concern. If the effect of bulking is not studied properly, the concrete designed will have an insufficient amount of sand resulting in a harsh mix. Bulking of sand will affect the yield of concrete for a given cement content.

Air entrainment and its effects in concrete • Aggregate ...

 · Median sand ranging from the No. 30 sieve to the No. 100 is the most effective at entraining air . Excessive fines, minus No. 100 material, causes a reduction in air entrainment. Because the use of chemical and mineral admixtures in addition to airentraining agents has become common practice, concrete users are always concerned about the effects of these admixtures on the airvoid system .

They give body to the concrete, reduce shrinkage and effect economy. One of the most important factors for producing workable concrete is a good gradation of aggregates. Good grading implies that a sample fraction of aggregates in required proportion such that the sample contains minimum voids. Samples of the well graded aggregate containing minimum voids require minimum paste to fill up the ...

Effects of Salt on Concrete

Effects of Salt on Concrete

 · Salt does not damage concrete, but the effects of salt can. That sounds weird, so we'll explain. Salt does not chemically react with hardened concrete. Salt does however lower the freezing point of water, attract moisture, and increase pressure of frozen water. Salt can also increase the freezethaw cycles if the temperature fluctuates between 15°F and 25°F. Concrete scaling can occur in ...
