Study of compressive strength of oil palm shell (OPS) concrete has been conducted by varying the content of admixture of silica fume and fly ash to increase concrete strength. Digital Image Correlation (DIC) was used as a tool to capture the physical change of concrete cube during the test which can be converted to load-displacement response by using open source sotware, Ncorr. It is evident that DIC can be carried out with ordinary camera DSLR which reveal from test result. Poison's ratio as a ratio between lateral and vertical displacement is succesly obtained. The value are between 0.2096 to 0.2264. Concrete strength improved by 30% to 43% by adding the admixture, silica fume and fly ash.
