. Nominal mixes are an easy, fast means of acquiring a fundamental concept of the Attributes from the completed concrete without having to execute screening here upfront.
Bonding agents are used to create a bond amongst outdated and new concrete (commonly a style of polymer) with large temperature tolerance and corrosion resistance.
