Mechanical Performance of Concrete Made with Recycled Aggregates from Concrete Pavements

open access: yesAdvances in Materials Science and Engineering, 2020
This research aims at analysing the mechanical performance of concrete with recycled aggregates from concrete pavements. First, the characteristics of various natural and recycled aggregates used in the concrete were thoroughly analysed.

EFFECTS OF ALTERNATIVE AGGREGATES ON CONCRETE STRENGTH

open access: yesProceedings of International Structural Engineering and Construction, 2016
Worldwide, large quantities of solid waste are generated by construction and demolition (C&D) activities and the car industry. At the same time, the availability of landfill space is diminishing, and most industrialized nations are actively promoting recycling procedures to reduce the amount of waste going to landfill.

Effects on Compressive and Tensile Strength of Concrete by Replacement of Natural Aggregates with various Percentages of Recycled Aggregates

open access: yesMehran University Research Journal of Engineering and Technology, 2022
Recycled aggregate concrete is required owing to environmental conservation and actual consumption of resources. In the construction industry, for the manufacturing of concrete the demand for replacement of ordinary aggregates by recycled aggregates has ...

Effect of Aggregate Size on Strength Characteristics of High Strength Lightweight Concrete [PDF]

open access: yesMaterials, 2020
Effects of aggregate size on the mechanical properties of lightweight concrete (LC) were investigated. Four gradings of lightweight aggregate (LWA) were designed and used to prepare the specimens for compressive strength, splitting tensile strength, and flexural strength tests.

Production of concretes using slag aggregates: Contribution of increasing the durability and sustainability of constructions

open access: yesCase Studies in Construction Materials, 2021
The main by-product of the steel industry is slag. This paper investigates the use of slag aggregates of electric arc furnace (EAFS) and ladle furnace slag (LFS) in replacement of fine and coarse conventional limestone aggregates, for the production of ...

PROPERTIES OF HARDENED CONCRETE USING CRUSHED CLAY BRICK AS AGGREGATES

open access: yesJournal of Engineering, 2011
This paper provides the result of an investigation to use of crushed clay brick as aggregates in producing concrete. Eight different crushed clay brick aggregate concretes were used in this investigation. Compressive strength, splitting tensile strength

Tensile strength and fracture of cemented granular aggregates [PDF]

open access: yesThe European Physical Journal E, 2012
Cemented granular aggregates include a broad class of geomaterials such as sedimentary rocks and some biomaterials such as the wheat endosperm. We present a 3D lattice element method for the simulation of such materials, modeled as a jammed assembly of particles bound together by a matrix partially filling the interstitial space.

Can We Truly Predict the Compressive Strength of Concrete without Knowing the Properties of Aggregates?

open access: yesApplied Sciences, 2018
This paper is focused on the influence of the geological nature and quality of the aggregates on the compressive strength of concrete and explains why it is important not to ignore the characteristics of aggregates in the estimation of the strength of ...

Effect of Recycled Aggregates on Strength and performance of Recylced Aggregate Concrete [PDF]

open access: yesE3S Web of Conferences, 2020
This study is taken up to utilise the recycled coarse aggregate and recycled fine aggregate as replacement of natural aggregate in concrete mix. It is required to find the percentage of recycled coarse aggragate and recycled fine aggregate, as the strength of concrete can not be achieved by using higher percentaged.
