significance of crushing machine by engineers

Compressive Strength of Brick Bricks are mainly used in construction of wall, floor, cornices and arches. Brick chips are also used as a substitute of stone chips in concrete mix where stone is not available or an economic solution is prefared. In all the above-mentioned cases, compression load governs. Due to this, compressive strength of bricks is a very important parameter.-significance of crushing machine by engineers-, Determination of Aggregate Impact Value Apparatus for Aggregate Impact Test. The apparatus as per IS: 2386 (Part IV) – 1963 consists of: (i) A testing machine weighing 45 to 60 kg and having a metal base with a painted lower surface of not less than 30 cm in diameter. It is supported on level and plane concrete floor of minimum 45 cm thickness.…… Get more +

7 LAB TESTS ON AGGREGATE TO CHECK QUALITY FOR USE IN

Sep 12, 2015Crushing Test Fig-1 Crushing Test Setup. One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS: 2386 part-IV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.Get more +

Top 6 Important Quality Tests Of Concrete

Aug 05, 2015Top 6 Important Quality Tests Of Concrete. The plus or minus sign is the symbol of tolerance of slump. Let say for example the slump of approved concrete design mix for your suspended slab is 150 mm +/- 25. It means that the drop of concrete after the slump cone is removed should not be more than 175 mm nor less than 125 mm.Get more +
