gravel‚ or crushed stone that‚ along with water and Portland cement. Aggregates are essential ingredient in concrete. For a good concrete mix‚ aggregates need to be clean‚ hard‚ strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates‚ which account for 60 to 75 percent of the total volume of concrete‚ are divided into two distinct categories - fine and coarse. Fine aggregates generally consist of natural sand

alkaline solution. Geopolymer concrete has significant advantages over standard concretes such as resistance to corrosion and fire‚ high compressive and tensile strengths and also less shrinkage. The development of geopolymer concrete is an important step towards the production of environmental friendly concretes. The purpose is apparently to reduce the carbon dioxide emission resulting from the production of Ordinary Portland Cement (OPC). The production of geopolymer concrete mostly relies on the curing

Q3: Describe and discuss the durability properties of hardened concrete. Durability is the ability of concrete to handle deterioration from the surroundings or at the service in which it is placed. The most important things that cause rust could be divided into two chemical and physical causes. The Chemical durability complications are disturbed with countless formulae reactions of cement-aggregate. On the other hand In the physical durability aspect problems are concerned from the aggregates
