Low Heat Golden Bay Cement

Low heat mass pours are largely beneficial with saving the associated costs and time with the decreased number of necessary joints because excess thermal energy is produced in large mass pours it can often lead to cracking of the concrete – and a low heat cementitous solution is required a mass pour of sufficient size will demand special attention to logistics and technicalities

A Closer Look Cement Types I Through V

Mar 18 2020 lower heat of hydration conversely type iv cement which is specified when low heat of hydration is necessary allows a maximum c 3 a content of 7 additionally type iv cement requires a minimum c 2 s content of 40 because c 2 s hydrates and hardens slowly and contributes to strength gain beyond one week this helps ensure slower strength
