Chockfast® Grouting Compounds Increase Foundation Service Life at Cement Plant Case Study

2023-11-17
●In cement manufacturing, the raw mill machine is a vital piece of equipment that is used to pulverize raw materials such as limestone, clay, and shale. The rotating table and rollers located inside the raw mill machine create the pressure and shear necessary to crush and grind the rock into small pieces. The crushed material is then sent to a cement mill and kiln to yield the final output.
●Problem
■At a cement manufacturer, the raw mill machine’s foundational plate faced vibration and cracks due to a lack of proper grouting. In addition to this, a significant gap existed between the concrete and the raw mill machine plate. The client was looking for a grouting solution that would prevent vibration, fill in the gap, and ensure a strong foundational surface.
●Solution
■Chockfast Red and Chockfast Orange grouts were installed due to their high compressive strength and strong bonding to concrete.
■To prepare for the Chockfast Red application, the previous foundational concrete was removed, and the surface was roughened to enhance adhesion. Chockfast Red was mixed using an in-house mortar mixer, poured into the foundation forms, and left to cure for 24 hours.
■The metal foundation plate was installed over the Chockfast Red grout and funnels placed throughout the plate in order to install Chockfast Orange underneath the equipment. Chockfast Orange epoxy grout was then poured into the metal forms of the foundation plate and left to cure for 24 hours.
