compressive strength analysis on recycled aggregate concrete

Strength analysis and validation of recycled aggregate

2020-10-1 · Compressive strength (CS) of Recycled Aggregate Concrete (RAC) determined at the age of 3, 7, 14 and 28 days and the flexural strength (FS) conducted at 7 and 28 days. For each grade of concrete five mixes were produced with varying percentage of RA (0%, 25%, 50%, 75%, and 100%).

Study on Compressive Strength of Recycled Aggregate Concrete

Experimental work for the compressive strength of recycled aggregate concrete was designed and performed with 264 cubes. The results indicated that the recycled coarse aggregate (RCA) replacement ratio has a remarkable influence on the compressive strength

Experimental Study of Compressive Strength of

Total four concrete mix batches were tested in which one mix was of normal aggregate concrete at 0% replaced by RCA and other are of Recycled aggregate concrete at 20%, 40% and 60% replaced by RCA. The result of the test are shown in the table 1.The compressive strength of the specimens was calculated by following formula.

Effect of Recycled Aggregate on Compressive Strength of

2018-6-19 · Compressive strength of recycled aggregate concrete was tested after 7-days, 14-days and 28-days after casting. Compressive strength of recycled aggregate concrete was compared with natural aggregate concrete. Result shows that compressive strength of recycled aggregate is decreased with increase in replacement of recycled aggregate. [5] 135

Effects of Recycled Aggregate on Concrete Mix and

Compressive strength decreased with the increase in the recycled aggregate content, and a concrete mix with 40% recycled aggregate exhibited the best strength. Concrete mix with 30% recycled aggregate had the lowest chloride penetration after 2 weeks of saturation and performed better than a concrete mix with 100% natural aggregate.

Study of recycled concrete aggregate quality and its

This work studies the physical and mechanical properties of recycled concrete aggregate (recycled aggregate from concrete waste) and their influence in structural recycled concrete compressive strength. For said purpose, a database has been developed with the experimental results of 152 works selected from over 250 international references. The processed database results indicate that the most

Compressive Strength of Concrete Cube Test,

2018-5-18 · Concrete being the major consumable material after water makes it quite inquisitive in its nature. The strength of concrete is majorly derived from aggregates, where-as cement and sand contribute binding and workability along with flowability to concrete.. This is an in-depth article on Compressive Strength of Concrete.

Micro-structural analysis of recycled aggregate concrete

2020-8-29 · applications is rarely reported because of its poorer compressive strength and high variability in mechanical behavior. This paper proposes a new approach in mixing concrete, namely “two-stage mixing approach (TSMA)”, intended to improve the compressive strength for recycled aggregate concrete and hence lower its strength variability.
