7、ConcreteC1093 Practice for Accreditation of Testing Agencies forMasonryC1611/C1611M Test Method for Slump Flow of Self-Consolidating Concrete3.Significance and Use3.1 Grout used in masonry is a fluid mixture of cementitiousmaterials and aggregate with a high water content for ease ofplacement.3.1.1
8、During construction,grout is placed within or betweenabsorptive masonry units.Excess water must be removed fromgrout specimens in order to provide compressive strength testresults more nearly indicative of the grout strength in the wall.In this test method,molds are made from masonry units havingthe
9、 same absorption and moisture content characteristics asthose being used in the construction.3.2 This test method is used to either help select groutproportions by comparing test values or as a quality control testfor uniformity of grout preparation during construction.3.3 The physical exposure cond
