Force and displacement data are recorded for 5 seconds prior to each test, while the test system holds the loading platen at initi al roof contact. The data recorded from 1 to 4 seconds of this hold time are averaged for each channel to produce a measurement offset that is subtracted from the data recorded during the crushing of the roof.

The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100. Lab Report

As per IS Code, the sample selection for the concrete cube test has listed below. The minimum value of Compressive Strength for a cube. As per IS 456, the individual compressive value of a concrete cube should not be less than 75% of its grade. Example – If the concrete grade is M20, then the individual crushing value should not be less than

By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures. Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength

The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be achieved at 28

The following are the major concrete cube test failure reasons, 1) Wrong Mix Poured: The concrete mix prepared is not as per the approved mix design for that particular strength. 2) Wrong Mix Design: There is a mistake in concrete mix design. It is not properly designed and strength is not properly calculated.

Name of the experiment: Aggregate Crushing value test. Objective: 1. Determine the aggregate crushing value of coarse aggregate. 2. Assess suitability of coarse aggregates for use in different types of road. Theory: The “aggregate crushing value” give a relative measure of the resistance of an aggregate to crushing under gradually applied

It is the ratio of force per unit area required to penetrate a soil mass with standard circular piston at the rate of 1.25 mm/min. to that required for the corresponding penetration of a standard material. The California Bearing Ratio Test (CBR Test) is a penetration test developed by California State Highway Department (U.S.A.) for evaluating the bearing capacity of subgrade soil for design

The transformer ratio test is used as both an acceptance test and a maintenance test, while the polarity test is primarily an acceptance test. The test equipment used is ordinarily a turns ratio tester designed for the purpose. If not available, input and output voltages can be measured, with at least 0.25 percent full-scale accuracy voltmeters

Compression testing is one of the most fundamental types of mechanical testing, alongside tensile and flexion tests. Compression tests are used to determine a material’s behavior under applied crushing loads, and are typically conducted by applying compressive pressure to a test specimen (usually of either a cuboid or cylindrical geometry) using platens or specialized fixtures on a universal

The aspect ratio of the test specimens is greater than that of mortar joints. The typical mortar joint, at ⅜ in. (9.5 mm) high with a depth of at least 1 in. (25 mm), results in a broad, stable configuration that is naturally able to carry more load than the comparatively taller and more slender mortar specimens used for material evaluation.
