Construction Studies Experiments
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. The order in which the experimentsare listed here does not specify the sequence to befollowed by the teacher.

Construction Studies Experiments
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
