In other words, with this work, the intention is to evaluate the feasibility of producing highperformance selfcompacting concrete with a less environmental impact, by replacing natural aggregates (NA) with fine and coarse recycled aggregates resulting from the precast industry, which allows the future use of this type of aggregates in the industrial process without reservations concerning ...
Keywords: SelfCompacting Concrete, Recycled Concrete Aggregate, Freeze/Thaw Test, Moist/Dry Test, Sulphate Attack Test. 1 Introduction The construction sector is a major contributor to one of the most important environmental problems: the lack of natural resources (Sandanayake et al., 2019), standing out the high
This investigation is an attempt to examine the influence of recycled aggregate on strength, permeability, resistance to acid attack, chloride penetration, and alkalinity of self compacting concrete. It is observed that recycled aggregate can be effectively used in the production of SCC without any significant reduction in strength and durability.
Performance of selfcompacting concrete made with coarse and . characteristics of concrete are remarkably improved by the replacement of coarse and fine recycled concrete aggregate, while others researchers (Kebaïli et al. 2015) indie that selfcompacting ability criteria were not satisfied for the concrete .
In this study, selfcompacting concrete (SCC) was developed with partial replacement of the coarse aggregates by polymeric waste (PW) from the recycling of refrigerators. In the SCC reference mixture, Portland cement, silica fume, sand, gravel and superplasticizer were used. The study also grouped the gravel as replaced by 5%, 10%, 15% and 20% ...
· Selfcompacting concrete (SCC) is a highly flowable concrete that fills formwork, and encapsulates even the most congested reinforcement without any external vibration. The concrete is homogeneous and has the same engineering properties and durability as traditional vibrated concrete. In the last two decades, concrete technology has made tremendous advances since the introduction of .
This article addresses to the issue of durability related properties of selfcompacting concrete (SCC) with the use of coarse recycled aggregates obtained from demolition of concrete structures. The objective was to verify the influence of recycled
Using recycled aggregates is a relatively recent scientific area, however, studies on this material in the manufacture of selfcompacting concrete have proven the feasibility thereof for conventional structural elements as well as highperformance and complex structural elements, densely reinforced structures, difficulttoaccess formwork and difficulttovibrate elements.
The use of recycled concrete aggregates from demolition waste and rubble in combination with cementitious Urbanization growth rate in India is veradditions in concrete has various advantages. industrializationFrom various literature it has been observed that Self Compacting Concrete(SCC) with recycled aggregate meet
· RA are obtained from the deconstruction and demolition waste which are typically made out of different construction materials such as concrete, bricks, tiles, stone, timber, glass, plastics and metal (Güneyisi et al., 2016).The deconstruction and demolition waste can be egorized as recycled concrete aggregates (RCA), recycled masonry aggregates and mixed recycled aggregates as .

The use of waste in civilengineering products, such as concrete and asphalt mixes, is a very effective strategy for reducing high consumption levels of Natural Aggregates (NA) in the construction sector. In this research, rejected precast concrete elements of high compressive strength are studied,following their crushing for use as a high quality Recycled Concrete Aggregate (RCA) in the ...

19 selfcompacting concrete with recycled aggregate (SCRAC). Recycled aggregates 20 were used to replace 30% of natural coarse aggregates by volume. The effects of 21 various replacement ratios of steel slag powder (SSP) to Portland cement (, 10%, 22 20%, 30%, 40%, and 50%) on the workability, mechanical properties, and durability
