Abstract Researchers worldwide have employed a varied array of sources to calculate the successful management of Construction and Demolition (C&DW). Limited research has been undertaken in the domain of Construction and Demolition Waste Management (C&DWM) and consequently leaving a large gap in the availability of effective management techniques. Due to the limited time available for building removal and materials collection, preparing for building materials reuse at the end of life is frequently a challenging task. In this research work Convolutional Neural Network-Long Short-Term Memory (CNN-LSTM) is proposed to predict the number of waste materials that are obtained from a building at… More >

Abstract Construction and demolition (C&D) waste has seriously affected the ecological environment. The utilization of C&D waste resources can greatly alleviate this problem, and it is an important way to help achieve the goal of zero carbon in 2050. In this study, insulation concrete blocks were developed with recycled aggregates, cement, fly ash as main raw materials, expanded polystyrene (EPS) insulation boards as block insulation filling material, and self-developed construction waste composite activator, interface enhancer, surface modifier and other additives. Through experimental research and performance test analysis, the best mix ratio of the product and the mechanism of each additive were… More >

Abstract

This work investigates the feasibility of utilizing reactive recycled powder (RP) from construction and demolition (C&D) waste as supplementary cementitious material (SCM) to achieve a ductile strain hardening cementitious composites (SHCC). The recycled mortar powder (RMP) from mortar waste, recycled concrete powder (RCP) from concrete waste and recycled brick powder (RBP) from clay brick waste were first prepared, and the micro-properties and tensile behavior of SHCC containing various types and replacement ratios of RPs were determined. The incorporated RP promotes pozzolanic and filler effects, while the hydration products in cementitious materials decrease with RP incorporation; therefore, the incorporated RP decreases… More >
