8、4.4.Summary of Test Method4.1 Polymer machinery grout of a flowable consistency ispoured into a hopper at one end of a shallow plastic trough witha clear plastic cover plate.4.2 A movable gate is raised,allowing the grout to flowfrom the hopper into the trough.The times for the grout to firstcontact
9、 the end plate and to establish full length contact withthe top cover plate are recorded and used as indices offlowability.4.3 After the grout hardens,the mold and top plate areremoved.The top surface of the grout is wire brushed to exposeany surface air bubbles or voids,and a visual estimate is mad
10、eof the percentage of grout top surface area that is in contactwith the plate.Visual guides are provided for comparativepurposes(see Fig.1 and Fig.2).NOTE1Two figures are used to visually represent sections of twodifferent types of void distribution as the rating of effective bearing areais based on
11、 comparison from these illustrations.The void distribution andappearance may vary from these illustrations based on the rheologicalcharacteristics of different grouts.It is suggested that a photograph of theactual grout surface be retained after the testing.5.Significance and Use5.1 Chemical-resista
