Aggregate strength, gradation, absorption, specific gravity, shape and texture are some of the physical and mechanical characteristics that contribute to the strength and durability of ...

Mechanical Properties Of Recycled Aggregates …

The application of recycled aggregate to use in construction activities have been practice by developed European countries and also of some Asian countries. This stone reports the results of an experimental study on the mechanical properties of recycled aggregate concrete (RAC) as compared to natural aggregate concrete (NAC).

PROPERTIES OF RECYCLED AGGREGATE CONCRETE

density of recycled aggregate was on the average by 10% lower compared to the bulk density of natural aggregates [6,9,10]. 2.5. Crushing and abrasion resistance Mechanical properties of recycled aggregate are primarily dependent on the quality of the original cement mortar present in the aggregate, and also, as

Properties of recycled aggregate concrete …

Aggregate image measurement system (AIMS) was used to measure and analyze the angularity, texture, sphericity and flatness and elongation (F&E) characteristic of recycled and natural coarse aggregate . Fig. 3-a, b, c and d show the morphological characteristics of recycled and natural coarse aggregate.

Enhancing mechanical and durability properties of …

The main difference between Recycled Concrete Aggregate (RCA) and Natural Aggregate (NA) is the mortar adhered on RCA. This stone presents the effect of RCA to concrete and a treatment method utilized to improve the properties of RCA, by reducing the amount of the adhered mortar, and therefore the properties of the Recycled Aggregate Concrete ...

Mechanical and Durability Properties of Recycled Aggregate Concrete: ... It is now recognized that the recycled aggregate concrete (RAC), where natural aggregates are replaced with recycled concrete aggregates, is a promising technology for conserving natural resources and reducing the environmental impact of concrete.

(PDF) Mechanical properties of recycled aggregate …

Influence of replacement ratio and water-cement ratio on the recycled concrete mechanical properties were analyzed by testing the compressive strength and tensile strength of the recycled concrete. Results show that the mechanical properties of recycled concrete, compared with common concrete, can meet the requirements of the project.

Effect of Recycled Coarse Aggregate on Concrete …

Based on the result of properties of Recycled Aggregate and natural coarse aggregate, it can be seen that specific gravity for natural coarse aggregate is higher than Recycled Aggregate, and the value of specific gravity for natural coarse aggregate is 2.64, it means that natural coarse aggregate meet the requirement of specific gravity.

Properties of Recycled Aggregate Concrete | …

17-6-2018 · Abstract. The important properties of fresh and hardened recycled aggregate concrete such as workability, compressive strength, split tensile strength, flexural strength, modulus of elasticity, density and ultrasonic pulse velocity (UPV) are discussed in detail in this chapter.

Mechanical and Durability Properties of Recycled …

Test parameters comprised the recycled aggregate replacement ratio, size of coarse aggregates, and mixing method used in the preparation of concrete. The results indicate that the compressive strength is not the only decisive factor on mechanical and durability-related properties of RACs.

PERMEABILITY PROPERTIES OF FINE RECYCLED AGGREGATE …

aggregate. Blue granite crushed stone aggregate of sizes 20 and 10 mm (0.78 in.) and 10 mm (0.39 in.) was used at the same ratio of 60:40 by volume as natural aggregate. Heating and rubbing treatment for RCA The presence of mortar was the main reason for the lower quality of the recycled aggregate compared to natural aggre - gate.

Construction aggregate - Wikipedia

Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.

Recycled Concrete Aggregates: Its Properties & Uses

Recycled concrete aggregate as such, holds original aggregate with hydrated cement paste. Hence first, that demolished concrete is cleaned from dirt and other loose particles. After that, it is broken into smaller pieces to produce aggregate known as recycled concrete aggregate. Recycled concrete aggregates are available in size of 20mm to 50mm.
