EXPERIMENTAL STUDY ON THE APPLICABILITY OF RECYCLED AGGREGATE

Two types of recycled aggregate concrete were produced using real ready-mixed concrete plant. Recycled coarse and fine aggregates (RG-RS) and in some cases recycled coarse aggregate and natural sand (RG-NS) were used in concrete production. Recycled aggregate concretes were transported by truck agitator from the concrete plant to work site.

ASTM C29 / C29M - 17a Standard Test Method for Bulk Density

1.1 This test method covers the determination of bulk density (“unit weight”) of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.

Experimental Study on Durability of Recycled Coarse Aggregate

The preliminary experimental research of freeze-thaw and anti-permeability composite durability of recycled aggregate concrete has carried on, the results show that the superposition damage of recycled aggregate concrete is more sensitive, and the damage is greater.

Experimental Investigation of Recycle Concrete Aggregate

In the present study, the recycled aggregates were subjected to a rubbing treatment with the Los Angeles abrasion machine to remove mortar. The number of revolutions and the weight of charges to be used in the Los Angeles abrasion machine are arrived at based on the abrasion results of natural coarse aggregate and recycled coarse aggregate.

An Experimental Study on Partial Replacement for Coarse

used as one such alternative for coarse aggregate. Owing to scarcity of coarse aggregate for the preparation of concrete, partial addition of E-waste with coarse aggregate was attempted. The work was conducted on M25 grade mix. The addition of coarse aggregate with E-waste in the range of 0%, 32%, 34%, 36%, and 38%. Finally the

Experimental research on durability of recycled aggregate

The freeze-thaw durability of recycled aggregate concrete has significance for the concrete buildings in the cold region. In this paper, the rapid freezing and thawing cycles experience on recycle aggregate concrete was conducted to study on the effects of recycle aggregate amount, water-binder ratio and fly ash on freeze-thaw durability of recycle aggregate concrete.

EXPERIMENTAL INVESTIGATION ON CONCRETE WITH REUSED AGGREGATE

replacements for this coarse aggregates. This paper is about the usage of Recycled Concrete Aggregate (RCA) to replace 50% of natural coarse aggregate in the Concrete. Due to usage of Recycled Concrete Aggregate, strength of the concrete will be reduced. So to improve the strength of concrete, admixtures can be added in it.

Experimental and finite element analysis of shrinkage of concrete

This study deals with an experimental and numerical investigation focused on the total shrinkage of concrete made with recycled coarse aggregates (RCA) and subjected to various isothermal temperatures. The objective of the experimental work is to assess the ...

iv) Up to 20% replacement of coarse aggregate with the recycled aggregate can be used in the concrete, when normal mixing method and normal curing is adopted. 20% RA taken concrete shown strength ...

Characterization of Recycled Coarse Aggregate (RCA) via a

May 20, 2014 · Recycled coarse aggregate (RCA) made from waste concrete is not a suitable structural material as it has high absorption of cement mortar, which adheres on the aggregate surface and on the tiny cracks thereon. Therefore, when using RCA made from waste concrete, much water must be added with the concrete, and slump loss occurs when transporting.

Replacement of recycled coarse aggregates with natural coarse

In this study we replaced natural aggregates with recycled aggregates in concrete cubes. This is the first part of the study we have to do. Here we are trying to see a pattern of how the strength decrease once we replace natural coarse aggregate (NCA) with recycled coarse aggregates (RCA). The percentages of replacement will be 0%, 50% and 100% ...
