Concrete Structures

ConcreteBasics.org thanks Vincent T. H. Chu  for granting permission to reproduce his answers to some of the most basic yet highly challenging civil engineering questions on Bridges, Concrete Structures, Piles & Foundations, Earthwork and Roadwork

Concrete Structures: Q-A :

1 What are the functions of different components of a typical expansion joint?
2 If on-site slump test fails, should engineers allow the contractor to continue the concreting works?
3 What is the function of shear keys in the design of retaining walls?
4 In designing concrete structures, normally maximum aggregate sizes are adopted with ranges from 10mm to 20mm. Does an increase of maximum aggregate size benefit the structures?
5 What are the major problems in using pumping for concreting works?
