Seminar Ppt on Green Concrete

Green concrete can be defined as the concrete with material as a partial or complete replacement for cement or fine or coarse aggregate. This means concrete that uses less energy in its production produces less carbon dioxide than normal concrete is green concrete.

The Effect of Aggregate Properties on Concrete

The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.

Aggregate Properties

A majority of the volume of concrete (60 – 80%) is occupied by aggregate. In fact, for most conventional concretes, more than 75% of the volume is aggregate. Aggregates are essential in concrete from the point of view of economy (since cement is expensive), dimensional stability (aggregates do not easily creep or shrink), stiffness, and abrasion resistance.

Title Slide

In general, concrete containing a calcareous coarse aggregate performs better under fire exposure than a concrete containing quartz or siliceous such as granite or quartzite. The coefficient of thermal expansion of aggregates ranges from 0.55 x 10-6 per C to 5 x 10-6 per C (1 x 10-6 per F to 9 x 10-6 per F).

Quartzite and chert (and flint) are important rock types when considering aggregate for concrete, as they are both commonly used in concrete and are potentially alkali–reactive. Classification of these rocks can be challenging and with this in mind, Hunt (1995) has devised an engineering classification of quartzite and chert to aid alkali–silica reactivity assessment.
