For the last decades, concrete materials and technology have been widely developing in many ways in order to achieve an economic and high quality product. But from the other hand concrete offersa wide range of capabilities to achieve a good balance between human needs and earth's capacity which is known as the sustainability. Two stage concrete (TSC) known sometimes as preplaced aggregate concrete (PAC) is a relatively as a new concrete type which has ability to satisfy the requirements of performance and sustainability. Its main concept depends on pre-packing the coarse aggregates in the formwork, then injecting cement mortar grout into the voids in between the aggregates. TSC differs from conventional concrete in having a higher percentage of coarse aggregates which are placed in direct contact with each other resulting in fewer voids that are to be filled with the cement mortar/grout. This low percentage of voids should have a positive impact on the concrete properties both on short and long term basis.The behaviour of TSC in compression has been well documented, but there are little published data on its behaviour in tension and modulus of elasticity. This paper presents results of experimental testing of TSC made with two types of coarse aggregates and three different mix proportions of grout. It was found that the modulus of elasticity of two-stage concrete is equivalent or higher than that of conventional concrete for the same compressive strength. Relationships of stress versus strain and modulus of elasticity versus compressive strength were statistically derived and elaborated.
