SSC JE Civil Engineering 25-Sep-2019 Shift 1 Solved Paper

(i) Vicat's Apparatus test used for determination of setting time of cement.
(ii) The test used for determining soundness of cement is known as "Le chatelier apparatus test."
(iii)The most common tensile strength test on cement is conducted by the application of uniaxial tension. This test is carried out by moulding cement-sand mortar briquettes, known as Briquette test method. Which are placed in a machine that can apply a tension load.
(iv)The fineness is usually measured by the Blaine air-permeability test that indirectly measures the surface area of the cement particles per unit mass.
Hence option (a) is correct.
