Influence of carbonated recycled concrete aggregate

2015-11-15  This work investigated the effect of carbon dioxide treatment of recycled concrete aggregate (RCA) on the performance of RCA and RCA mortar. The results indicated that carbonation increased the apparent density, and reduced both water absorption and the crushing value of the RCA.

Effect of carbonated coarse recycled concrete

2019-10-1  Abstract. The effects of carbonated coarse recycled concrete aggregate (RCA) on properties and microstructure of recycled aggregate concrete (RAC) were investigated in this study. The water absorption of 5–10 mm and 10–20 mm coarse RCA was reduced by 30% and 22%, and their corresponding apparent density increased by 4.8% and 3.2% after carbonation ...

2019-11-1  Old cement mortars attached on recycled concrete aggregates (RCA) seriously affects the durability of the recycled aggregate concrete (RAC). Revealing the variation of the transport properties of cement mortar after subjecting to accelerated carbonation treatment is crucial with respect to understanding the effects of carbonated RCA on the durability of RAC.

Influence of Recycled Aggregate on Interfacial

Abstract. This study is conducted (1) to examine the influence of recycled aggregate on interfacial transition zone (ITZ), strength, chloride penetration, and carbonation of concrete, and (2) to propose a method for improving strength, chloride penetration, and carbonation resistances of concrete using recycled aggregates.

ISSN 2348 – 7968 Influence of Recycled Coarse

2015-12-16  The size of aggregate used in a concrete mix, however, also has an influence on the compressive strength values. Rahman et al concluded that regardless of the size of aggregate used in a mix, the concrete cubes they tested had similar strength characteristics during the first 14 days of curing but this was not the case for the last 14 days. Concrete made from small-sized RCA revealed much higher compressive strength in the last 14 days of curing compared to concrete made with large-sized aggregate. An increase in size of RCA resulted in a consequent reduction in strength gain. With regards to the findings in the present study, these might have been affected by the lack of adequate distribution of aggregate particles to form homogenous mixes of fresh concrete. Shortage of an adequate amount of small size aggregate may lead to an increase of voids within the concrete mix. The voids then contribute to the porosity of the concrete and ultimately affect the compressive strength of the concrete.

Influence of service time of recycled coarse aggregate

2019-9-4  The mechanical properties of recycled aggregate concrete (RAC) may be affected by the service time of parent concrete used to produce the recycled coarse aggregate (RCA), which has not been experimentally investigated. Current models primarily relate RAC elastic modulus to its compressive strength. These models cannot describe the difference in the mechanisms of the influence of the ...
