Description of concrete shotcrete machine
Concrete shotcrete machine is a chemical admixture in powder form used to create waterproof concrete. KIM is used in place of externally applied surface membranes to protect against moisture transmission, chemical attack, and corrosion of reinforcing steel.
Inspect the ready-mix shotcrete batch ticket to verify that the correct shotcrete mixture has been supplied with KIM added at the specified addition rate. Ensure that the shotcrete air content and slump are in the specified range prior to discharge into the shotcrete pump. Slump: Add a mid or high range water reducer (superplasticizer) as necessary to achieve the required slump. Only add water with the approval of the shotcrete supplier’s quality control technician. Record all water additions on the batch ticket and do not exceed the specified water-cement ratio (max 0.40 for shotcrete). Air Content: Add additional air-entraining admixture as necessary to achieve the required air content.
