Mounting Stone - Whip Mix

The SI unit of stress or pressure is the pascal, which has the symbol Pa, that is equal to 1 N/m 2, 0. lbs/in 2 in Imperial units, or 9.9 × 10 −6 atmospheres. Because the wire has fractured at a stress of 100 megapascals (MPa), its tensile strength is 100 MPa, where 1 MPa = 1 N/mm 2 = 145.04 psi.. In the English or Imperial system of measurement, the stress is expressed in pounds ...

samples of stone to plaster in the ratios of 1:1, 1:3, and 1:4 gave an increased compressive strength of (9.8, 9.7, and 9.3 MPa) compared with the strength of plaster alone (7.9 MPa) . The result reveals that the highest amount of compressive strength was recorded by the samples made in the ratio of stone / plaster equal to 1:1.
