Identify the material test and X/Y variables corresponding to the peaked curve shown.
Concrete workability:water–cement ratio/slump Concrete cube:water–cement ratio/28-day compressive strength Ultrasonic pulse velocity:pulse speed/compressive strength Sand bulking:moisture percentage/percentage volume increase Practise this question in The GATE Grind →
Show answer and explanation Correct answer: (D) Sand bulking:moisture percentage/percentage volume increase
Explanation Small additions of moisture form films that separate sand grains, increasing bulk volume. With further water, the bulking decreases as the sand approaches saturation. This rise-and-fall curve identifies the sand-bulking test, D. The alternatives have different typical trend shapes.
