Influence of Recycled Aggregate Quality on the Mechanical Properties of Concrete

Communications, 2014
The use of recycled construction and demolition waste - especially recycled concrete - as an aggregate for new concrete mixes, leads to saving of natural resources and helps to reduce the pressure on landfilling sites.

Compressive strength improvement for recycled concrete aggregate

MATEC Web of Conferences, 2018
Increasing amount of construction waste and, concrete remnants, in particular pose a serious problem. Concrete waste exist in large amounts, do not decay and need long time for disintegration.

Study on Mechanical Properties of Recycled Aggregate Concrete with Cement-Based Crystalline Materials [PDF]

E3S Web of Conferences
The acceleration of urbanization has led to the increasing scale of construction waste, which has caused a lot of waste of resources, and recycled aggregate concrete technology can effectively utilize these wastes. Due to the existence of complex systems

Recycled Concrete as Aggregate for Structural Concrete Production [PDF]

Sustainability, 2010
A comparative analysis of the experimental results of the properties of fresh and hardened concrete with different replacement ratios of natural with recycled coarse aggregate is presented in the paper. Recycled aggregate was made by crushing the waste concrete of laboratory test cubes and precast concrete columns. Three types of concrete mixtures were

Properties of recycled aggregates from different composition and its influence on concrete strength

Revista IBRACON de Estruturas e Materiais, 2021
: As a solution to the high depletion of natural resources and huge waste generated by the construction industry, the use of coarse recycled aggregate has become a trend in many countries. The construction and demolition waste is heterogeneous and mostly

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

Advanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Recycled concrete aggregate properties improvement

Engineering Today, 2023
In recent years, there has been increasing interest in the use of recycled concrete aggregate (RCA) as a sustainable alternative to natural aggregates in construction. RCA is obtained by crushing and reusing old concrete, which contains both the original aggregate and a cement mortar layer.
