COMMON APPARATUS AND EQUIPMENT USED IN TESTING OF MATERIALS SIEVE SET  A sieve, or sifter, is a device for separating wanted elements from unwanted material or for characterizing the particle size distribution of a sample of (aggregates, sand, and other soil particles) SLUMP CONE  A metal mold in the form of a truncated cone with a top diameter of 4"(102mm), a bottom diameter of 8"(203mm), and a height of 12"(305mm), used to fabricate the specimen for a slump test.  The concrete slump test is an empirical test that measures the workability of fresh concrete. More specifically, it measures the consistency of the concrete in that specific batch. VARIOUS MOLDS Three types of molds use in material testing lab for preparation of Concrete specimen : CUBE MOLDS CYLINDER MOLDS BEAM MOLDS HYDROMETER  A hydrometer is an instrument used to measure the specific gravity (or relative density) of liquids; that is, the ratio of the density of the liquid to the density of water. UNIVERSAL TESTING MACHINE  An instrument so designed that it is capable of exerting a tensile, compressive, or transverse stress on a specimen under test. Further, it can be adapted for the determination of Brinell hardness, ductility, cold bend, and other properties. The machine consists essentially of three systems: loading, weighing, and indicating, the loading being applied either mechanically or hydraulically. CONCRETE MIXER TAMPING ROD Tamping rods are dimensionally accurate rods used to tamp fresh concrete into cylinder molds and slump cones to eliminate voids and excess air. THERMOMETER  It is an instrument for measuring and indicating temperature, typically one consisting of a narrow, hermetically sealed glass tube marked with graduations and having at one end a bulb containing mercury or alcohol which extends along the tube as it expands. ELECTRIC OVEN  Laboratory ovens are ovens for high-forced volume thermal convection applications. These ovens generally provide uniform temperatures throughout. Process applications for laboratory ovens can be for annealing, die-bond curing, drying, Polyimide baking, sterilizing, and other industrial laboratory functions. THANK YOU
