This document presents research on using phase change materials (PCM) in concrete construction to improve thermal energy efficiency of buildings. Specifically, it examines incorporating paraffin wax and bee wax PCM into concrete blocks. Test blocks were produced with cavities containing each PCM and a control without PCM. Temperature readings found that blocks with paraffin wax maintained the largest temperature difference over time, indicating it provided the best thermal regulation. In conclusion, incorporating paraffin wax PCM into concrete construction materials can help reduce energy demands for heating and cooling buildings.

3. Introduction
 Phase change materials (PCM) are ‘‘latent’’ thermal storage materials
possessing a large amount of heat energy stored during its phase change
stage .The energy required to change the phase of a substance is known
as latent heat.
 In this project we are using pcm integrated into building materials for
thermal energy storage applications, and much attention has been given
to works concerned with the achievement and assessment of applying
pcm in concrete wall. Because concrete have high specific heat capacity
as well as the thermal conductivity which will eventually affect their
thermal performance.

20. CONCLUSION
 We get the better result by using paraffin wax as compared to
bee wax so we prefer to use paraffin wax in concrete block.
