“…The main reason for replacement of aggregate, which is the major component in concrete blocks, is the primary sources savings [50]. There are many recycled waste materials which is possible to use as partial or full replacement of aggregate in concrete blocks such as recycled concrete waste [51,52,53,54,55,56,57], crushed brick waste [11,58,59,60,61,62,63,64,65,66], glass waste [67,68,69,70], crump rubber waste [71,72,73], ceramic and tile industry waste [74], marble waste [75,76], plastic waste [77] and concrete slurry waste [78,79]. Moreover, due to its unique characteristics, the recycled materials could positively influence some properties of concrete blocks such as thermal conductivity, thermal resistance [65] or mechanical properties [67].…”

The Utilization of Recycled Masonry Aggregate and Recycled EPS for Concrete Blocks for Mortarless Masonry

et al. 2019

The main aim of this paper is to carry out the environmentally based enhancement of a concrete mixture containing recycled materials whilst considering natural resource consumption as well as mechanical and thermal property levels. The developed concrete is intended to be used in mortarless masonry wall structures. Ten concrete mixtures with different types and replacement rates of recycled masonry aggregate and recycled expanded polystyrene were prepared, and their mechanical and thermal properties were experimentally investigated. It was found that the use of recycled masonry aggregate led to better thermal properties while maintaining sufficient mechanical properties. On the contrary, the addition of recycled expanded polystyrene did not significantly affect the thermal properties of concrete, but the mechanical properties considerably declined. For this reason, the recycled masonry aggregate is suitable to use as an aggregate for concrete masonry blocks for wall structures.

“…Ganjian et al (2015) used granulated blast furnace, cement by-pass dust, run-of-station ash, basic oxygen slag, plasterboard gypsum, incinerator bottom ash, recycled crushed glass, recycled concrete aggregate, recycled bricks, steel fiber and PVA fiber for aggregate and cement replacement in paving block production. Other studies used recycled demolition aggregates (Poon and Chan, 2006;Poon and Cheung, 2007;Soutsos et al, 2011;Jankovic et al, 2012), rubber waste (Ling, 2012), red mud and fly ash (Kumar and Kumar, 2013), slag cement (El Nouhy, 2013), recycled CRT funnel glass (Ling and Poon, 2014) and crushed ceramic (Sadek and El Nouhy, 2014) for replacement of conventional aggregates. Yunhong et al (2014) and Jacoby and Pelisser (2015) noted that high volume of wastes are generated by ceramic companies and currently there is no effective means to treat or reuse it.…”

“…Reference [12] obtained similar results for recycled concretes incorporating up to 75% of brick materials. Reference [89], who investigated the effect of crushed ceramic in the production of interlocking paving units, concluded that samples with 50% replacement of natural coarse aggregate by ceramic satisfied the requirement of Class 3.…”

Paving with Precast Concrete Made with Recycled Mixed Ceramic Aggregates: A Viable Technical Option for the Valorization of Construction and Demolition Wastes (CDW)

et al. 2018

This research aimed to prove the feasibility of producing two types of precast elements widely used in construction, such as curbstones and paving blocks, using recycled concrete made with a 50% substitution of the natural gravel by recycled mixed aggregates with a significant ceramic content (>30%). In order to prove the quality of such mass concrete recycled precast elements, two different mixes were used: the first one was a conventional concrete mix provided by Prefabricados de Hormigón Pavimentos Páramo S.L., one of the collaborating companies in this study, and the other was a mixture in which wt 50% of the natural coarse aggregates were substituted for recycled mixed aggregates ceramic (RMAc). This recycled aggregate is a heterogeneous mixture of unbound aggregates, concrete, ceramic, etc., used as a secondary recycled aggregate and commonly produced in a lot of recycling plants in many European countries. This material was supplied by Tecnología y Reciclado S.L., the other collaborating company. Both mixtures were representative in order to establish the comparative behavior between them, taking into account that smaller percentages of replacement of the natural with recycled aggregates will also produce good results. This percentage of substitution represents a high saving of natural resources (gravel) and maintains a balanced behavior of the recycled concrete, so this new material can be considered to be a viable and reliable option for precast mass concrete paving elements. The characterization of the recycled precast elements, covering mechanical, microstructural, and durability properties, showed mostly similar behavior when compared to the analogous industrially-produced pieces made with conventional concrete.
