(A) Pycometer                                                 (B) Slump Cone

(C) Universal Testing Machine                        (D) Vicat’s Apparatus

Answer:  D. (Vicat’s Apparatus)

A cement paste is said to be of normal consistency when a 300 gram, 10-mm-diameter Vicat needle penetrates 10 + 1 mm below the surface in 30 seconds.
