The various methods of hand compaction are as given below. 1. Rodding. It is a method of poking with 2m long, 16 mm dia rod at sharp corners and edges. The thickness of layers for rodding should be 15 to 20 cm. 2. Ramming. It is generally used for compaction on ground in plain concrete. It is not used either in RCC or on upper floors.

CarbonCure's technology injects CO₂ into concrete where it then converts into a mineral. This makes the concrete stronger and enables mix optimization.
Ready-mix concrete can be used for buildings, roadways, walls and more. 10. Volumetric Concrete. This concrete was created as an alternative to ready-mix concrete to address the problem of long distances between the concrete plant and construction sites. It requires specialized trucks known as volumetric mobile mixers.
