Feb 21, 2011 Crushing strength of the stone per unit area is the maximum load at which the sample crushes or fails divided by the area of the bearing face of the specimen. Crystalline Test on Building Stone. At least four cubes of stone with side as 40mm are taken. They are dried for 72 hrs and weighed. They are then immersed in 14 solution of Na2SO4 for 2 hours.
Record this load. The Crushing strength or compressive strength is given by the formula as C= P A. Where, C = compressive strength P = Load at failure A = cross-sectional area of bearing face of the specimen. Then the average value of the six specimens is calculated and the result is recorded for that stone.
Test result indicates that, compressive strength of specimen mix with 35 of sand replacing stone dust and 3 of cement replacing stone dust increases 21.33 and 22.76 respectively than the.
Jul 20, 2018 Compressive strength test. This test is vital for evaluating the stone’s resistance to crushing loads. A wall stone has to bear the compressive load of the stone’s weight. A stone floor has to withstand loads of people and heavy objects. So, compressive strength is the highest load per unit area borne by the stone without giving in. A.
