The workload involved in the recycling of materials is minimal but with economic and technical efficiency. Autoclaved aerated concrete (ACC Autoclaved aerated concrete) has been widely applied in construction works in Vietnam and is considered a reasonable replacement of fired bricks due to lower volume density, and better …
The purpose of this study was to reuse desulfurization (De-S) slag in the production of autoclaved aerated concrete (AAC). The non-magnetic fraction of De-S slag is rich in calcium and silicon ...
Abstract. Autoclaved aerated concrete (AAC) has many benefits for structures, such as heat insulation, sound insulation, fire resistance, reduced dead weight, and many more. AAC products include ...

Despite data uncertainties, recycling of pd-AAC is advantageous for several recycling options, including the production of AAC, light mortar, lightweight aggregate concrete, and shuttering blocks ...
Steel slag is a by-product of steel-making processes in which excess lime is often added to remove impurities from liquid steel. Therefore, steel slag is normally rich in calcium compounds, and it thus has the potential for the production of autoclaved aerated concrete (AAC).
Therefore, new recycling options are needed. Current research approaches propose different open-loop recycling routes for post-demolition AAC, e.g. lightweight aggregate concrete, lightweight mortar, no-fines concrete, floor screed, animal bedding, oil- and chemical binders, and insulating fills for voids and interstitial spaces.
In this study, the mechanical performance and thermal insulation properties of autoclaved aerated concrete (AAFC) with ceramic polishing slag (CPS) were investigated using chemical ing technology at a density of 500 kg/m 3.

Autoclaved aerated concrete (AAC) has a porous structure and excellent thermal properties. Therefore, it is a frequently used building material for masonry units, prefabricated reinforced components and lightweight mineral insulation boards with increasing popularity. Post-demolition AAC is currently mainly disposed of in landfills. …
Recycling these post-demolition AAC wastes could protect primary resources and landfill capacities and reduce greenhouse gas emissions. But, recycling of post-demolition AAC is not yet established.
Autoclaved aerated concrete is an excellent thermal insulation wall material, but with a large amount of waste. This paper describes the high-temperature activation and rehydration activity of …
This paper presents an investigation of the use of recycled lightweight aggregate from waste autoclaved aerated concrete block to make lightweight pervious concrete (LWPC). The effects of fine sand (SA) and fly ash (FA) as additive materials on LWPC properties were also studied. The density, total void ratio, water permeability, …
Autoclaved aerated concrete (AAC) is a widely used building material for masonry units, prefabricated reinforced components, and lightweight mineral insulation boards. Its low thermal conductivity and good fire resistance increase its popularity in residential buildings. Thus, post-demolition wastes are expected to increase in the future. However, post …
Recycling aerated concrete blocks (ACB) and sintered clay bricks (SCB) is difficult due to their high porosity and low strength for concrete production. The workability and mechanical properties of cementitious composites will be severely deteriorated when ACB and SCB are used as recycled coarse aggregate.
Autoclaved aerated concrete (AAC) is the lightest masonry material available in today's building industry. It shows properties, such as high strength per unit weight, lesser density, lower shrinkage, higher thermal insulation, and fire resistance as compared to traditional concrete. Not only engineering properties of AAC make it popular in …
The practice production process of non-autoclaved aerated concrete containing WDC are given in Fig. 8. According to the mix proportion showed in Table 2, the crushed WDC together with cement, quicklime, gypsum and fly ash were accurately weighted and fed into a full-automatic mixer through pipelining.
This article presents the results of an experimental study on a new protocol to create a non-autoclaved cellular concrete containing a partial substitution of sand by an equivalent volume of pure perlite and perlite waste.

Others focus on open-loop recycling where pd-AAC is used in the light mortar [13], lightweight aggregate concrete [13,14], floor screed [15], and shuttering block production [14]. ...
Present study is dealing with the possible recycling methods of aerated concrete construction (building and prefabrication) waste material. Besides the most obvious application (load bearing aggregate) many other utilization methods were shown (covering tiles, shuttering elements, stumped concrete) and investigated.
To make autoclaved aerated concrete, the main materials used in this study are PC40 cement, AAC waste products, gypsum, quicklime, ground natural sand, aluminum powder. The chemical composition of ...
Autoclaved aerated concrete waste (AACW) is a common low-strength cement-based construction and demolition waste, which is currently disposed by landfills and hard to be directly used as supplementary cementitious material. The present work proposed a potential approach incorporating AACW for cement substitution in …
