Cohesion Testing System Chemgrout

Cohesion Testing System. The plate cohesimeter devised by Lombardi is used to measure the cohesion of grout. It involves a thin plate 100mm x 100mm x 1mm thick with rough surfaces on which grout, providing it has some cohesion, can stick. Depending on the real injection setting, the plate surface can be structurally adapted by different grooves, ...

Lombardi Plate Cohesion Meter - Water Retention to

Divide the weight of grout by the area of the plate to obtain the weight per unit area. The weight per unit area is divided by the specific weight of the grout to determine the thickness of grout that stuck to the plate. This thickness, when converted to mm, is the cohesion (Deere and Lombardi 1985).

2021-6-14  In such circumstances, travel can be limited through the increase in cohesion. For the measurement of this grout cohesion, Lombardi developed a plate cohesiometer, also referred to as P.C.M. It involves a thin plate of 100 x 100 x 1 mm with rough surfaces on which the grout – provided that it has some cohesion - can stick.

2021-5-25  A Lombardi plate cohesion meter was used to measure the cohesion. A picture of the plate cohe-sion meter is shown in Figure 5-3. There is no ASTM standard the plate cohesion meter, but the dimensions are described in Weaver (1991). The meter was constructed of a thin steel plate 10 centimeters by 10 centimeters by about 3 millimeters thick.
