Concept and significance of the Aggregate crushing value test. The ' aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a …

Abstract. These test methods cover production and acceptance tests for concrete pipes, manhole sections, and tiles. Tests include procedures for evaluating external load crushing strength, flat slab top, core strength, absorption, hydrostatic, permeability, manhole step, cylinder, gasket lubricant, joint shear, alkalinity, and gasket measurements.

A companion publication "The Concrete Pipe and Portal Culvert Installation Manual" gives details of how these products should be installed. 1.2. SCOPE The content of this handbook covers the pre-construction activities associated with precast concrete pipe and portal culverts, namely those undertaken by the designer of the project.

crushing tests on concrete cores or cured concrete cylinders; by an absorption test of the concrete from the wall of the pipe for each mix design that is used on an order; and by inspection of the finished pipe including amount and placement of reinforce-ment to determine its conformance with the accepted design and its freedom from defects.

The complete procedure of testing concrete pipe and clay pipe are contained in ASTM Standard C497, Methods of Testing Concrete Pipe and Tile, and ASTM Standard C301, Methods of Testing Clay Pipe. The external load crushing strength test with the load applied by three-edge bearing is the accepted test method for both clay and concrete pipe.

The standard test in general use for concrete pipe of all sizes is the three-edge bearing test. This test is used to determine two values, generally accepted as indicative of the quality and strength of concrete pipe: the load to produce a 0. Ol-inch crack and the load to produce ultimate failure.

The test series included three concrete culvert pipes, 18 inches, 24 inches, and 36 inches in diameter, respectively. Each pipe was 193 ft long and laid on a slope of 0.20 per cent, except that the 24-in. pipe was on a slope, of 0.224 per cent. The pipes tested were all manufactured by the cast-and-vibrated
