It was expected because recycled aggregate is high in water absorption. revealed that mortar over RA is lead to low slump of RAC. Fig. 3.1 Slump for Concrete Mixes Compressive TestThe compressive strength results are presented in Table 3.2.

The recycled concrete waste aggregate RCWA was tested for grading specific gravity percent absorption and impact and crushing crushed. For the fresh concrete mix slump and compaction factor test were carried out. Concrete samples are wet cured and tested at 7 and 28 days for compressive strength.

Yoonseok Shin proposed a multiple regression model MRM for predicting the compressive strength of recycled aggregate concrete RAC and the results show that it is useful for predicting the compressive strength of RAC 19 . 1.3. The Use of Recycled Aggregate Concrete in

The lowest highest recycled aggregate concrete compressive strength predicted is 2.332 MPa which shows there is a huge difference between the highest and the lowest predicted compressive concrete strength. The significant difference was ultimately influenced by the age of the recycled aggregate.

The results show that the compressive strength prediction of the recycled aggregate concrete is predictable with a very high accuracy using the proposed ANN-based model. The proposed ANN-based model can be used further for optimising the proportion of waste material and other ingredients for different targets of concrete compressive strength.

Recycled concrete aggregates are being considered for use in the OHare Modernization Project OMP. Laboratory testing using a two-stage mixing method showed that using RCA from Chicago OHare International Airport for the coarse aggregate reduces bleeding and segregation and produces similar workability compressive strength and .

Hence the ratio of split tensile strength to compressive strength plays a vital role in defining the concrete properties. In this review the impact of design parameters on the strength ratio of various grades of Self-Compacting Concrete SCC with recycled aggregate is assessed.

However the compressive strength of young concrete typically after 1 day of curing is more influenced by the incorporation of recycled aggregates than the mixes tested after 14 and 28 days. This is in agreement with the results of Kou et al. 7 who shows that the difference in compression strength between a natural aggregate concrete and .

Feb 28 2019 Different portions of the recycled aggregate hold varying measures of specific gravity characterizing the cured casts strength compression-resistance and modulus elasticity. However using a recycled aggregate of more than 65 can impact the mixs durability significantly reducing its physical properties tenfold.

In recent years research on recycled aggregate concrete has become a hot issue in the field of civil engineering. This paper mainly studies the size effects on compressive and tensile strengths of the recycled aggregate concrete. Firstly four sets of recycled concrete cube specimens with different sizes are produced in the laboratory.
