1 Introduction

It has been demonstrated that quality of the recycled concrete aggregate depends on the content of the porous and cement mortar attached to the recycled coarse aggregate (RCA) [1] The presence of the weak phase results in lower density and higher water absorption of RCA than natural coarse aggregate (NCA) which unfavorably affects the properties of fresh and hardened concrete [2]

The air content was low about 1% The bulk density of mixes differed depending on the aggregate used The highest density was achieved for magnetite aggregate M1 due to the higher density of magnetite in relation to barite 4 80 g/cm 3 and 4 05–4 18 g/cm 3 respectively The compressive strength tested after 28 days of curing was within the

An experimental program was carried out to investigate the usability of recycled coarse aggregate (RCA) concrete with and without ground granulated blast furnace slag (GGBFS) The RCA was derived from concrete having compressive strength of 47 6 MPa Twelve concrete mixtures having various RCA (0–25–50–) and GGBFS (0–30–60%) replacement levels were designed with a water-to-binder

2 2 RECYCLED CONCRETE AS COARSE AGGREGATE IN CONCRETE Recent cracking and faulting problems occurring in jointed concrete pavements made with recycled concrete coarse aggregate led to an examination of some of the basic physical and mechanical properties of concrete made with recycled concrete as coarse aggregate
