Recycled Aggregate Concretes (RACs) for Structural Use:

2016-10-15 The determination of the parameters of concrete (i.e., elasticity modulus and tensile strength) is a crucial task in material engineering. For this purpose, structural codes propose some empirical formulas to estimate the parameters of materials and are useful for designers rather than the experimental process. However, the estimated results usually vary for different

Mix Design and Properties of Recycled Aggregate

2014-8-26 This work is devoted to the study of fresh and hardened properties of concrete containing recycled gravel. Four formulations were studied, the concrete of reference and three concretes containing recycled gravel with 30, 65 and 100 % replacement ratios. All materials were formulated on the basis of S4 class of flowability and a target C35 class of compressive

Workability study of concretes made with recycled mortar ...

2013-1-22 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, rough-textured surfaces and particles with quite irregular shape from RA. Besides that, the slump test is a static test, whose result is influenced by its own weight and by

Recycled Concrete Aggregates: A Review International ...

2013-3-29 After demolition of old roads and buildings, the removed concrete is often considered worthless and disposed of as demolition waste. By collecting the used concrete and breaking it up, recycled concrete aggregate (RCA) is created (Fig. 1).This paper focuses on coarse RCA which is the coarse aggregate from the original concrete that is created after the mortar is

Recycled Concrete Aggregate - an overview ScienceDirect ...

Recycled concrete aggregate (RCA) is the designation used in BS 8500-2 for recycled aggregate principally comprising crushed concrete. Designations of recycled aggregate other than RCA are of lower quality and may contain significant quantities of masonry which would preclude or limit their use in structural concrete.

Utilization of Recycled Aggregate Concrete for Marine Site ...

2021-7-28 This research aimed to create value of construction and demolition waste to be able used as a recycled coarse aggregate (RCA) in durable concrete, based on 7-year field investigation in marine site. Fly ash was used to substitute Portland cement type I in RCA concrete varied from 0 to 50% by weight of binder with three W/B ratios and comparing to

Strength and Durability Evaluation of Recycled Aggregate ...

2015-5-14 This paper discusses the suitability of producing concrete with 100 % recycled aggregate to meet durability and strength requirements for different applications. Aggregate strength, gradation, absorption, specific gravity, shape and texture are some of the physical and mechanical characteristics that contribute to the strength and durability of concrete.

Mechanical Properties of Recycled Aggregate Concretes ...

In this study, the impact of steel fibres and Silica Fume (SF) on the mechanical properties of recycled aggregate concretes made of two different types of Recycled Coarse Aggregates (RCA) sourced from both low- and high-strength concretes were evaluated through conducting 60 compressive strength tests. The RCAs were used as replacement levels of 50% and 100% of

Performance of Recycled Aggregate Concrete Made with

Concrete containing recycled aggregates have different properties from concrete containing natural aggregates. This work investigates, firstly, the possibility of using recycled refractory bricks (RBA) as coarse aggregate for concrete, and secondly, finds the ideal replacement percentage of natural coarse aggregate (NCA) by RBA. For this, an experimental study was carried out to

Response and Modeling of Steel Tubes Filled with

The engineering properties of concrete with recycled aggregates (RAC) can vary more widely than normal aggregate concretes (NAC). Because concrete-filled steel tubes do not rely solely on the concrete in compression, using RAC in a concrete-filled steel tube (RACFST) is a sustainable structural solution.
