Sand Cement Brick Incorporating Palm Oil Clinker as Partial Replacement for Fine Aggregate Norhaiza Ghazali1,a *, Khairunisa Muthusamy1,b, Mohd Faizal Md Jaafar1,c, Khairul Anuar Shahid1,d, Roziah Zailan3,e , Muhamad Zul Afkar Mohamed Jafri1,f 1Faculty of Civil Engineering Technology, Universiti Malaysia Pahang, Lebuhraya Tun Razak, 26300 Gambang, Pahang, Malaysia.
The water absorption of the investigated bricks ranges from 10 to 12 percent, which disqualifies them from the Engineering A or B categories of MS 76:1972 and BS 3921:1985 but satisfies the ASTM standards for the severe weathering brick categories.

The damage constitutive model in appendix C in code could be applied directly in some low precision calculation and engineering application.
Research on mechanical properties and constitutive relation is the foundation of application, design and analyze for FRC in engineering, which makes significant sense in engineering construction of FRC.
Thus the toughness index R is usually defined as the area of the material’s stress-strain curve in engineering [4].
In general, the above damage model could be applied directly in some low precision calculation and engineering application.
