2019-5-1 Some researchers have evaluated soils with recycled materials including rubber soils and recycled glass owing to their light weight in terms of dynamic performance, and energy absorbency,. They exhibited a greater capacity for energy absorbency and tended to decrease the stress and shocks transferred to the ground. In the design of mix proportion, combined with the characteristics of recycled coarse aggregate itself and meeting the requirements of concrete workability and slump, the Recycled concrete aggregates (RCA) can be used as a replacement of natural aggregates for a concrete production to save natural sources and also to decrease amount of demolition waste which has to The result of the permeability test shows that the porosity of recycled concrete is large when taken as a whole, and the water content is higher after steeping, which reduces the strength of the material. Mercury intrusion results also show that the pore structure of recycled aggregate is poor and that there are more internal micro-cracks. 2021-2-22 Integrated pore index. 1. Introduction. Recycled aggregate is prepared with waste concrete by crushing, screening, and removing impurities. Using waste concrete to produce recycled aggregate concrete can reduce the consumption of natural aggregate and promote the effective consumption of construction waste [1]. Use of recycled concrete aggregates (RCA) as a pavement material is one of the most sustainable engineering applications for the pavement industry. Investigation on the performance characteristics of RCA, such as elastic and plastic deformations of RCA is therefore, needed to assess RCA's application as an unbound pavement material. 2008-11-3 characteristics of fresh and hardened recycled aggregate concrete and natural aggregate concrete is relatively narrower han reported for laboratoryt -crushed recycled aggregate concrete mixes. For concrete without blast furnace slag, having similar volumetric mix proportions and workability, 2013-12-1 The old cement paste on the RFA surface forms a weak, porous, crackly layer, whereas the fine aggregate further increases the porosity of RFA and weakens its quality. The porous characteristic of RFA increases its water absorption, leading to many microflaws formed inside the concrete (as proven in the following microanalysis). 2020-4-20 Schematic diagram of recycled concrete coarse aggregate. Recycled concrete aggregates were commonly used in road bases and some secondary roads in China at present stage. The application in the terms of building structure was merely in the low-rise demonstration house. 2018-1-30 Recycled aggregates were collected from a local waste concrete recycling company located in the Daegu-Kyungpook area in Korea. Their sizes are variable depending on the production process and their potential usage. When the aggregate is small (10–20 mm), it consists predominantly of either mortar or crushed natural aggregate.
