![]() ASTM Test Sands for specific test methods are available in a range of compositions and grades and meet specific ASTM and AASHTO standards.Available in two models – one with a larger orifice for thick grouts. Grout Flow Cone Sets measure the flowability of hydraulic grout in preplaced aggregate concrete as determined by the time of discharge through an orifice.The Grout Sample Box is single-use and sets up easily for molding samples for testing. Grout Sample Box is specially designed to form samples, store, and ship. ![]() Produces properly sized vertical caps for accurate test results. Grout Prism Capping Stand for compressive strength specimens of masonry grout up to 3.5in (89mm) square.Laboratory Cement Mortar Mixers with two models of industrial-grade Laboratory Mixers, Planetary and Large Planetary, that meet ASTM and AASHTO specification requirements for consistent, thorough blending of mortar, cement, and other materials.They have a 10in rigid cast bronze table and cast iron frame and are available in both a manual and motorized style. Flow Tables used for determining the flow consistency of mortars.Mortar Penetrometers available in a free-standing floor model or handheld, both styles are ideal for testing prepared mortars and grouts in field and laboratory settings for initial and final set times.Vicat Apparatus is used to determine consistency and time of the set of cement paste and other similar materials, Vicat Apparatus is also available in a modified model for determination of false set.Related products include a cement autoclave, length comparator, prism molds, and mortar bar container. Length Change Test Apparatus measures length changes of cast prisms that are not related to the applied load.Each model meets ASTM C227, ASTM C151, ASTM C490, AASHTO T 107M and AASHTO R 70 standards. Prism Molds in the single or two-gang configuration are made of corrosion-resistant steel or stainless steel to form 1x1x10in, 2x2x10in, or 3x3x10 prisms.Cube Molds are available constructed of plastic or different metals to form cube specimens of 2x2in, 6圆in, or ISO 150x150mm many meeting ASTM and AASHTO standards.The specific gravity, surface moisture, and absorption values calculated in this test method are used for the design of internally-cured concrete mixtures. This test method covers the determination of the relative density (specific gravity), surface moisture, and absorption properties of lightweight fine aggregate in the field or laboratory. Determining the Relative Density (Specific Gravity), Moisture Content, and Absorption of Lightweight Aggregate This method of test describes the procedure for determining the pH for aggregate samples. This test is designed to determine the proportion of dust or clay material in fine aggregates using a mechanical shaker.įine Aggregate Angularity - FAA (Uncompacted Void Content of Fine Aggregate) Sand Equivalent Value of Soils and Fine Aggregate Deleterious materials may consist of wood, clay lumps, friable particles, coal and lignite, flat or elongated particles, glassy particles, and iron ore. This method of test describes the procedure for determining the percentages, by weight, of deleterious materials in aggregate. It is not intended for use in the sieve analysis of aggregates recovered from bituminous mixtures or for the sieve analysis of mineral fillers. This method of test covers a procedure for the determination of the particle size distribution of fine and coarse aggregates, using sieves with square openings. Sieve Analysis of Fine and Coarse Aggregates All substances other than shell and all material passing the 75 micrometer sieve shall be considered foreign matter.ĭetermining the Quantity of Clam Shell in Clam and Reef Shell MixturesĮffective, this procedure is no longer applicable.Īmount of Material Finer than No. This method is designed to determine the percent by weight of foreign matter in clam shell, reef shell, and mixtures of clam and reef shell. This is to minimize the variations between the larger field sample and sample size needed for testing.ĭetermining the Amount of Foreign Matter in Clam Shell, Reef Shell, and Mixtures of Clam and Reef ShellĮffective, this procedure is no longer applicable. This procedure is intended for reducing of the gross sample to laboratory size using a mechanical splitting device. This procedure is designed to determine the total moisture and free moisture contents of coarse and fine aggregates for Portland cement concrete by drying the material on a hot plate or in an oven. This procedure is intended to determine the particle size distribution of mineral fillers by sieve analysis.ĭetermining Total Moisture and Free Moisture in Aggregate (Coarse and Fine)
