200 tones in different models. Portable models are very convenient and useful for site use where carrying frequently the specimens for testing in a standard laboratory is inconvenient and uneconomical. With special attachments, the machines can also be used for bricks, hallow or solid concrete blocks, using appropriate capacity machine. In general compression testing machine consists of a load frame with suitable platens and a pumping unit with pressure gauge, either hand operated or electrically-cum-hand operated. Load frame and pumping unit are connected by pressure pipes. Wooden packing

We have been in this line for many years, our products is very competitive and resonable . Wooden cases, 100kg, 620x460x1530

1. Size of concrete specimens for compression strength test Concrete cubic specimen: 150X150X150mm, 100X100X100mm, 200X200X200mm Cylindrical concrete specimen: diameter 150X300mm, diameter 100X200mm, diameter 200X400mm 2. Brief introduction of concrete compressive strength test procedure 1) Placing the concrete specimen---place the test specimen on the lower bearing block. Carefully align the axis of the specimen with the center of thrust of the spherically seated block. 2) Apply the load continuously and without shock until the specimen fails and record the maximum load carried by the concrete specimen during the test. Note the type of failure and the appearance of the concrete. 3.Relative test method GB/T 50081 standard for test method of mechanical properties on ordinary concrete ASTM C39 standard test method for compressive strength of cylindrical concrete ASTM E74 practice of calibration of force-measuring instruments for verifying the force indication of testing machine 4.

1. Introduction and test principle of compression strength measuring The compression testing machine is to measure compression strength of corrugated boxes in the situation of pressure and protect functions of packages for the objects filled in the packages. Test principle: (1) Corrugated boxes compression strength test, loading to the corrugated boxes using a compression testing machine at a certain constant rate untill corrugated boxes are broken or till certain load or displacement are reached. (2) Corrugated boxes stacking test, loading a certain force to the corrugated box using a compression testing machine untill corrugated box is broken or sustain a certain time period. When measuring deformation of corrugated box during compression test, an original load should be set as a datum point. The datum point can refer to the following chart: Average compression force(N)Original force(N) 101-200 10 201-1000 25 1001-2000 100 2001-10000 250 10001-20000 1000 200001-100000 2500 2. Functions of compression testing machine This machine is applicable to metal, cementing compound, tubes, sectional bars, aerospace, petrochemical, waterproof rolls, wire and cable, textile, fiber, rubber, ceramics, food, mechanical packaging, geo-textile, film, wood, paper and other industries and quality supervision department, and it also can be used in college for teaching demonstration. 3.
