Jun 29, 2007 · Tiếng Anh trong Xây dựng. RCC – ROLLER COMPACTED CONCRETE (PART 1) Definition. ACI 116 defines RCC as “concrete compacted by pneumatic roller; in its unhardened stage, will support a (vibratory) roller while being compacted.

Methods of Concrete Compaction and Types of Vibrators

Compaction also helps to get the concrete to surround all the reinforcement steel and to fill all corners of the form, however small they may be. Compaction should be applied uniformly to the entire concrete mass. If concrete is well compacted, we achieve durable concrete, but over compaction also leads to the segregation of concrete.

Sulphate Resisting Cement

Sulphate Resisting Cement can also be used in mass concrete where reduced heat liberation is required. As with Portland cements, the resistance to acid solutions is limited, but concrete life expectancy will be maximised by using Sulphate Resisting Cement at high cement content and low water to cement ratio in fully compacted and cured concrete
