Structure Strength Correction Value for Concrete’s Mix Proportion Strength Using Low-Quality Recycled Aggregate

open access: yesCrystals, 2022
To develop a design method for concrete using low-quality recycled aggregates, an experimental study was conducted on applicability to examine the structural strength correction value (S value) and calculation of mix proportion strength of recycled ...

EFFECT OF RECYCLED FINE AGGREGATE ON PROPERTIES OF MORTAR

open access: yesCeramics - Silikaty, 2023
To improve the utilisation rate of recycled fine aggregate (RFA), five different replacement rates of RFA were used in this article. Recycled mortar (RM) was used as the research object to test its consistency, compressive strength, flexural strength, chloride ion migration coefficient, and frost resistance.

Analyses of the geometrical properties of fine recycled aggregates

open access: yesActa Polytechnica CTU Proceedings, 2022
The acquisition of natural sand and dumping of fine recycled aggregates (FRA) are two serious environmental problems that can be solved simultaneously by using FRA as replacement of natural sand in high-end applications. In the past, FRA has been considered an unwanted by-product of construction and demolition waste (CDW) processing, due to the high ...

Correlation of porosity and properties of recycled fine aggregate concrete with fly ash

open access: yesActa Polytechnica CTU Proceedings, 2022
In this paper, we presented the experimental discussion of samples of recycled aggregate concrete with replacement of natural fine aggregate by recycled fine aggregate. Three mix kinds were produced and, for each of these three kinds, two levels of water

Compressive Strength of Concrete with Recycled Concrete Aggregate as Coarse Aggregate and Recycled Paving Block Aggregate as Fine Aggregate Partially Substituted by Recycled Brick Aggregate

open access: yesAsian Journal of Applied Sciences, 2020
An excessive extraction of natural resources for aggregate in concrete mix can caused an environmental degradation.  According to Indonesia ministry of industry in 2017, the use of cement is predicted will reach 84,96 million tons, that can affected the use of aggregate for concrete mix are quadruplet to 250 – 350 million tons. Opimally, the use ...

Effect of Recycled Aggregate Quality on the Bond Behavior and Shear Strength of RC Members

open access: yesApplied Sciences, 2018
During the aggregate crushing process, natural aggregate and clinging mortar from existing concrete will inevitably produce small cracks and weak bonds between the aggregate and the existing cement mortar.
