• Abstract:

  Provisions for the use of structural lightweight aggregate concrete are included in British codes of practice but limitations are applied to the design values that may be used. This paper is concerned with the strength in shear. The paper reviews the published test data and describes a series of tests on beams, both with and without shear reinforcement. On the basis of the review and the tests, it is concluded that the code provisions are unnecessarily conservative.
