Report Title : Aggregate Properties of Some Hong Kong Rocks (1992), 212 p. (Reprinted, 1995)

Author : T.Y. Irfan, A. Cipullo, A.D. Burnett & J.M. Nash


This GEO Report consists of eight Technical Notes on selected aggregate properties of various granitic and volcanic rocks in Hong Kong. These Technical Notes were prepared as part of the Fresh Rock Testing Programme initiated in 1985, which provide data on characterization and possible usage of each of the Territory’s major rock types. The Technical Notes area presented in separate sections in this report. Their titles are as follows:

  • Section 1: Aggregate Properties of Medium-Grained Granite from Turret Hill Quarry
  • Section 2: Aggregate Properties of Monzonite from Turret Hill Quarry
  • Section 3: Aggregate Properties of Coarse-Grained Granite in Lai King
  • Section 4: Aggregate Properties of Fine-to Medium-Grained Granite from Ma Yau Tong
  • Section 5: Aggregate Properties of Fine- and Fine-to Medium-Grained Granites from Anderson Road
  • Section 6: Aggregate Properties of Medium-Grained Granite from Diamond Hill
  • Section 7: Aggregate Properties of Fine-, Medium-, and Megacrystic Granites from Lamma Island
  • Section 8: Aggregate Properties of Volcanic Rock Types from ‘Spun’ Sites at Mount Davis and Chai Wan

The report gives results of selected aggregate and rock index tests carried out on fresh rock samples from selected sites and discusses the results and suitability of the rocks as aggregate in comparison with typical aggregate acceptance values.
