Boron compounds are commonly used as a cementitious composite material for the attenuation of neutron and gamma radiation in HPC-M40. Boron compounds play a major role in the concrete for radiation shielding properties but addition of boric acid (H 3 BO 3 ) to concrete drastically reduce hardening and strength. Commonly for radiation shielding of high thermal neutron boron based materials used in high purity concrete. In this study, different percentages of boric acid 1, 2, 3, 4 & 5% were added to the high-performance concrete (HPC) and the effects on hydration process and strength were determined. Boron compounds will modify the active sites in the cement material and increase the setting time. The hydration of cement in addition to boric acid in the high-performance concrete has been studied using, X-ray diffraction, Fourier Transfer Infrared Spectrometry (FT-IR) and Field Emission Scanning Electron Microscopy (FESEM). The addition of boric acid concentration into the concrete specimen it is very strength til 60 th day of curing. At the end of curing days compressive strength dramatically improved.
