Question

The rate of creep generally _________ with the _________ of the size of aggregates.

(a) Increase, increase

(b) Decrease, decease

(c) Increase, decrease

(d) 2.5, 12mm

This question was posed to me in semester exam.

This is a very interesting question from Factors Affecting Creep and Elasticity topic in division Elasticity, Creep and Shrinkage of Concrete Technology

Answer 1

The correct answer is:

(b) Decrease, decrease

The rate of creep generally decreases with the decrease in the size of aggregates. Smaller aggregates tend to have a more favorable effect on reducing creep compared to larger aggregates, as they provide a denser and more rigid matrix, reducing the extent of deformation over time.
