SUGGESTED EXPERIMENTS: -

As a guide the following list has beencompiled. It is not intended that all of theseexperiments must be done, nor it is intended toexclude other experiments which a teacher or Student mayfind suitable to their project.

Some of the Experiments that we are using this year - on area like:-

  • The Slump test
  • The Compactor test
  • Cube Test
  • Silt test
  • Strength of building materials
  • The drip on a concrete cill or no drip on a concrete cill
  • Capillary reaction on two pieces of glass
  • Test concrete head with and with out steel
  • The use of damp proof course
  • Fire test on Building materials
  • Water absorption test on insulation
  • Water absorption test on glue on different timbers
  • Circulation of water – heating system ( science equipment required)
  • Other that you covered in science that relate to construction studies
  • Heat test – using several types of insulations
  • Strength test – compare joints for strength in relation to your projects.
  • Strength test – compare joints for strength using two types of glue , use weight to compare
