What is the crush strength test method? The crush strength test method measures the maximum compressive force a material can withstand without failure. It’s conducted by applying a gradually increasing compressive load to the specimen until it collapses or deforms significantly. The crush strength is then calculated based on the maximum force . Explanation: Compressive strength of following types of bricks is given below: First-class bricks - 10.5 N/mm 2; Common building bricks - 3.5 N/mm 2; Second class bricks - 7 N/mm 2; As per IS 1077: 1992 code, the common burnt clay bricks are classified into various classes based on their average compressive strength as mentioned below in the tabulated form:
Minimum three specimens should be tested at each selected age. If the strength of any specimen varies by more than 15 percent of average strength, the results of such specimens should be rejected. The average of three specimens gives the crushing strength of concrete. The strength requirements of concrete. Calculations of Compressive Strength

Note down the value of failure load and find out the crushing strength value of brick. Minimum crushing strength of brick is 3.50N/mm2.if it is less than 3.50 N/mm2, then it is not useful for construction purpose. ROHINI COLLEGE .
The bricks with crushing strength of 7 to 14 N/mm2 are graded as A and those having above 14 N/mm2 are graded. as AA. (3) Hardness test on bricks: In this test, a scratch is made on brick surface with the help of a finger nail. If no impression is left on the surface, the brick is r sufficiently hard. .
Procedure The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm.The aggregates must be in a surface dry condition before testing. The aggregates may be dried by heating at 100 oC – 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary. यह परीक्षण ईंटों की Comphressive strength निर्धारित करने के लिए किया जाता है। इसके अलावा ईंटों की शक्ति परीक्षण को कुचलने(Crushing Test) के रूप में जाना जाता है। आम तौर पर .For a high-quality brick, the amount of water absorption must not exceed 20% of the dry brick weight. 2. Crushing or compressive strength test. The crushing strength is determined by placing a brick in a compression testing machine that applies pressure on the brick until it .
The minimum crushing strength of bricks should be 3.50N/mm², any less, and that brick is unsuitable for construction. Brick Hardness Tests. High-quality clay bricks should resist scratches against sharp objects. If there are no scratch impressions, then it’s hard enough to be used. . This test is important because it can unveil lumps and .Test Method Sections Cold Crushing Strength 4 to 9 Modulus of Rupture 10 to 15 .
