1.	How many layers of concrete are placed to fill a slump cone?(a) 5 layers(b) 3 equal layers by volume(c) 3 equal layers by height(d) 5 layers by volumeThis question was posed to me in an online interview.The origin of the question is Testing of Cement topic in portion Types of Cement and Testing of Cement of Concrete Technology
Answer» Correct OPTION is (B) 3 equal layers by volume To elaborate: Fill the mold 12 inches high in the shape of the frustum of a cone that is 8 inches in diameter at the BOTTOM and 4 inches in diameter at the top. Then fill it in three equal layers by volume, not by height.
