Due to rapid industrialization and economic growth, the generation of construction and demolition waste (CDW) from the demolishing of buildings is increasing in Vietnam. At present, the Vietnamese government is promoting proper CDW management and reuse/recycling of CDW, supporting protection of the environment (Circular No. 08/2017/TT-BXD) and sound socio-economic development (Directive No. 41/2000/CT-TTg).

The paper presents experimental results and structural analysis of reinforced concrete (RC) columns made of recycled aggregate concrete (RAC) and natural aggregate concrete (NAC) under concentric compressive load. The ratio of recycled aggregates in mixture (i.e, replacement ratio, r in %) was 0, 50, and 100% by mass, where r = 0% corresponding to NAC.

This study presents an experimental investigation on the recycling of waste incineration bottom ash (IBA) as a fine aggregate in the production of interlocking concrete bricks (ICB). Before being used, the concentration of heavy metal in IBA was determined to confirm it is a non-toxic material. In this study, the IBA was used to replace crushed sand (CSA) in the brick mixtures at different replacement levels of 0%, 25%, 50%, 75%, and 100% (by volume).

Polymer modified mortars using either recycled waste concrete fine aggregate (WCFA) or artificial marble waste fine aggregate (AMWFA) were prepared and investigated for the purpose of feasibility of recycling. The replacement ratio of recycled materials also changed to investigate the effect of it on mechanical and physical properties. The water–cement ratio was increased as the replacement ratio of either AMWFA or WCFA in mortar in the absence of styrene-butadiene rubber (SBR) latex. The presence of SBR for both WCFA and AMWFA gave the increase of the air content.

The paper focuses on the shaking test program, including materials, similitude law and scaled model, instruments, seismic waves and loading program. Consequently, a comprehensive understanding on the process of shake table test is revealed thanks to the results of an investigation on a precast frame structure made of recycled aggregate concrete.

The aim of this study is to evaluate the effect of fly ash on the properties of fresh and harden recycled aggregate concrete based on alkali-activated slag. The aggregate of concrete mixtures was prepared with partial replacement of recycled aggregate, which was collected from construction demolish waste.
