Information for Ordering Concrete When ordering pre-mixed concrete, you will need to tell the supplier: Name and address for delivery The use of the concrete (i.e. driveway, housing slab, commercial) The amount you need in cubic

Carbonation and Corrosion

TeamCivil Concrete, Durability

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,

Concrete Aggregates: Effects and Classification
