1.	High strength concrete is used in prestressed member?(a) To ovecome bursting stresses at the ends(b) To provide high bond stresses(c) To overcome cracks due to shrinkage(d) To overcome bursting stresses, provide high bond stresses and overcome cracksThis question was posed to me during an interview.This intriguing question originated from Structural Designing and Thumb Rules topic in portion Valuation, Reports Technical and Design Data of Civil Engineering Drawing
Answer» CORRECT choice is (d) To overcome BURSTING stresses, PROVIDE high bond stresses and overcome cracks Easy explanation: The PRIMARY DIFFERENCE between high-strength concrete and normal-strength concrete relates to the compressive strength that refers to the maximum resistance of a concrete sample to applied pressure. Although there is no precise point of separation between high-strength concrete and normal-strength concrete, the American Concrete Institute defines high-strength concrete as concrete with a compressive strength greater than 6,000 psi.
