Performance of Pervious Concrete with Recycled Concrete Aggregate
Introduction Pervious concrete pavements act as a stormwater management tool. In recent times, several cities around the world have encountered frequent flooding due to the combined results of increased rainfall and high impermeable surface areas. As a result, the drainage system gets chocked leading to flash flooding, thus causing severe…
Recycled Concrete Aggregates – Its Uses, Properties, Advantages & Disadvantages
History Recycled concrete aggregates or Crushed concrete aggregates has been in use since the ancient times, only to be integrated with gravel, sand, and cement to ensure durability. The practice was first recorded in the 1860s. US construction companies were reluctant to use the technique at first since crushing cured…
Strengthening of Bridge Structure Using Carbon Fiber Reinforced Polymer (CFRP) System
