WORKABILITY STUDY FOR RECYCLED AGGREGATES
properties of recycled aggregates (RA) have been investigated with the aim of using them in concrete manufacture This benefit This benefit includes a reduction of the amount of natural aggregates extracted from quarries and riverbeds, which are used in concreteThe test results revealed that RCA significantly decreased the workability of concrete RCA also affected the compressive strength, modulus of elasticity, and Properties of HighWorkability Concrete with Recycled 22/01/2013 The use of recycled aggregates (RA) for concrete production usually involves a reduction of the workability as measured by slump This reduction is mainly due to higher absorption rates, roughtextured surfaces and particles with quite irregular shape from RAWorkability study of concretes made with recycled mortar
Sustainable Construction: Use of Recycled Concrete Aggregate
07/07/2015 Experimental results indicated that for concretes containing recycled coarse aggregates, as cleanliness of the recycled aggregate particles decreased, workability and compressive strength decreased, whereas air content increased For concretes containing recycled fines, workability generally increased with lower replacement level, and decreased Concrete with 80% RA showed good workability and mechanical properties The compressive strength of the concrete with 80% RA was 60 MPa at 28 days and 77 MPa at 56 days chloride penetration Influence of quality of recycled aggregates on the 01/03/2013 The densities of recycled aggregate concretes made with unsaturated recycled aggregate are below those of the control concrete despite the reduction in the effective water/cement ratio In addition, this effect isolates the greater porosity of these aggregates In the case of concrete with the same effective water/cement ratio, the density decreases with the Durability of recycled aggregate concrete ScienceDirect

18/08/2015 Of all the recycled aggregates those produced from crushed concrete, recycled concrete aggregates (RCA), have been vastly reported It is shown that the creep of concrete increases at a decreasing 01/05/2018 Although the researches on recycled aggregate concrete (RAC) has been going on for nearly 70 years , the use of RA in concrete structures is still limited due to its longterm durability concerns With the decrease of natural aggregate resources and the increase of waste concrete generation, RAC has become a hot research topic around the world Durability of Durability of recycled aggregate concrete – A review Il y a 2 jours After concrete mixing, which was conducted in stages to maximise concrete workability , the fresh tests, slump test (EN The shrinkage behaviour of recycled aggregate concrete has been analysed in this article It has been found that the addition of recycled aggregate (RA) increases the shrinkage of both highperformance and selfcompacting Shrinkage prediction of recycled aggregate structural

01/01/2021 This paper experimentally investigates the workability and mechanical performance of recycled aggregate concrete (RAC) It evaluates the influence of using metakaolin (MK) as cement replacement material on the performance of RAC The cement was replaced with MK at three contents (10%, 20% and 30%) In total, five mixes were preparedWorkability and EarlyAge Strength of Recycled Aggregate Concrete Incorporating Basalt Fibers Shahrukh Shoaib 1, Hilal ElHassan 1, Bilal ElAriss 1, Tamer ElMaaddawy 1 1 United Arab Emirates University, Department of Civil and Environmental Engineering PO Box 15551, Al Ain, United Arab EmiratesWorkability and EarlyAge Strength of Recycled Aggregate This study presents the effects of recycled concrete aggregate (RCA) on the key fresh and hardened properties of concrete RCA was used to produce highworkability concrete substituting 0100% Properties of HighWorkability Concrete with
Workability and Rheology of Fresh Recycled Aggregate Concrete
02/10/2016 The higher heterogeneity in terms of experimental slump measure occurs indeed when recycled aggregate concrete is tested In this chapter, a review of the existing experimental methods for the evaluation of fresh concrete workability is given Additionally, the behavior of fresh concrete is explored, aiming to understand which physical This study presents the effects of recycled concrete aggregate (RCA) on the key fresh and hardened properties of concrete RCA was used to produce highworkability concrete substituting 0100% natural coarse aggregate (NCA) Properties of highworkability concrete with recycled The workability of the recycled aggregate concrete is slightly lower than that of the conventional concrete The Recycled aggregate concrete is in close proximity to normal concrete in terms of split tensile strength The slump of recycled aggregate concrete is more than the normal concrete At the end , it can be said that the RCA upto 50 % can be used for A STUDY ON RECYCLED CONCRETE AGGREGATES
