- Graded concrete, functionally graded materials, compressive strength, modulus of elasticity
- Graded concrete is one of the functionally graded materials in civil engineering that can reduce the use of cement to create a high-performance structural element. The graded concrete is formed by combining two distinguish concrete mixes or more which have different strength so that the elements with varying material properties in a certain direction are obtained. The results of previous studies stated that the concrete compressive strength of the graded concrete was determined by the lowest strength while the studies discussing the resulting modulus of elasticity had not been conducted intensively. This research aimed to analyse the effect of concrete strength disparity in graded concrete to the modulus of elasticity. Six concrete cylindrical models were analysed using the Strand7 programme to obtain the stress-strain relationship on compression. The data is then analysed to obtain the modulus of elasticity of each model. The results show that the graded concrete can increase the modulus of elasticity of the concrete, and can be further improved by combining two drastically different concrete strength. The application of graded concrete can increase the serviceability level of structural elements and reduce the deflection due to working loads.
