The research was purposed to determine value of the capacity and flexural behavior of concrete-wood composite beam. In this test was used a beam with sizes is 5x10x115 cm on the simple supported by means of a one-point loading. The wood that has been used as a composite is camphor and yellow balau. The position of the layer is divided into three types: layers of wood in A-type is 1cm at the upper and 0.5cm at the bottom, B-type is 0.5cm at the upper and 1cm at the bottom, and Ctype is 0.5cm at left and right sides. Wood layer on the composite beams is associated with a nail and embedded in the concrete. The point of this research is to observed the value of Modulus of Elasticity (MOE) and Modulus of Rupture (MOR), and crack pattern. The results of this study indicate that the addition of a layer of composite beam can hold the crack and destruction of beam. Composite of concrete-wood also increase flexural strength, with cracking model flexure and bending the wood layer.
