| dc.description.abstract | Currently, scale down mock up test is widely practiced in construction industry to predict
the possible temperature rise and temperature differential in mass concrete construction.
Also, it can be used to validate the finite element thermal and structural models and
thereby correctly predict the risk of thermal cracking in actual mass concrete structures.
Accordingly, a case project was selected to verify the prediction accuracy of cracking risk
in mass concrete structure. This study results show that the combination of finite element
modeling and scale-down mock up test is the most suitable way to predict the possible
thermal cracking risk in mass concrete structural elements. This can be mainly applied to
identify the suitable insulation material for the mass concrete construction to prevent the
structure from early age thermal surface cracking. Further, this study proves that widely
practice maximum allowable temperature limits 20◦C is more conservative for medium
grade mass concrete construction in tropical countries like Sri Lanka and it contribute to
increase the cost in curing plan | en_US |
