It is shown that replacing of coarse and 50% of fine recycled aggregates with normal ones, S100C and S50f, led to 20 mm reduction of slump flow compared to the reference sample S. Simultaneous use of recycled fine and coarse aggregate in the S100C50f has reduced the slump flow by 50 mm.

Coarse Aggregate is 3 % and the value of Recycled Aggregate is %, while the standard for absorption is %. Furthermore, in finally, the value of Los Angeles for Natural Coarse Aggregate is %, while the value for Recycled

Recycled coarse aggregate was replaced with induction furnace slag by 0%, 25%, 50%, 75%, and for each target strength. Samples prepared from these concretes were tested for workability, compressive strength, splitting tensile strength, modulus of elasticity, and durability properties, porosity, absorption, and rapid chloride penetration.

The recycled coarse aggregate is obtained from the crushed laboratory tested concrete cubes. Pozzolanic materials nano silica and rice husk ash were used as a partial replacement of cement by weight in varying percentages 5%, % and 1%, %, % respectively.

Again natural aggregates were replaced by recycled coarse aggregates (RCA) in % of 0%, 10%, 20%, 30% 50% and . Thus total thirty different trial mixes were prepared and the effects of RCA with fly ash, on fresh and hardended properties have been determined.

Influence of Recycled Construction Materials Aggregate on Mechanical and Physical Properties of Concrete 1245 Rahal [3] presented results of an experimental study on some of the mechanical properties of recycled concrete aggregate as compared to those of natural aggregate. The specimens tested at ages 1, 3, 7, 14, 28 and 56 days.

Influence of amount of recycled coarse aggregates and ... In this study recycled coarse aggregates obtained by crushed concrete were used for concrete production. Four different recycled aggregate concretes were produced; made with 0%, 25%, 50% and of recycled coarse aggregates.

mechanical properties for the recycled aggregate concrete. Meanwhile, the alkalinity of recycled aggregate concrete, chloride and sulphate contents of recycled aggregate have not been adversely affected. In the procedure shown in [12], the coarse recycled concrete aggregates were kept immersed in HCl with a molarity of mole for 24 h.

and recycled concrete aggregates to replace certain amount of cement and natural coarse aggregates and reduces cost of cement. Silica fume is a mineral admixture and is byproduct of producing silicon metal or ferrosilicon alloys.
