The production of ceramsite from WAS is an effective way to realize the utilization of sludge. This paper comprehensively describes the use of WAS as raw material, adding clay, cement, glass powder, shale, coal gangue, river sediment, pulverized fly ash and other auxiliary materials (AM) to produce sintered sewage sludge ceramsite and …
If this calcining process meets well with the production process of a certain building material, CCS can be fully utilized as a resource, but there is rare work on this regard. Ceramsite is a product formed by calcining soil in a rotary kiln at 1050–1250 °C (Xu et al., 2008; Bao et al., 2014). The typical appearance of ceramsite is round or ...
1. Introduction. Drinking water treatment residual (DWTR) is an inevitable by-product generated during potable water production (Liu et al., 2020b; Zhao et al., 2021).DWTR is traditionally regarded as a non-hazardous material (Xu et al., 2020), and the disposal of DWTR is one of the major costs of water treatment plants although various …
Ceramsite is a type of granular solid particle made with ceramsite production line by sintering with clay, shale and gangue. Such features as light weight, low water absorption, good anti-seismic property, frost resisting and corrosion resistance make ceramsite and ceramsite sand products widely used in construction and petroleum field.
the most common reuse is low-value-added building materials. A novel processing method for preparing ultra-lightweight ceramsite with fly ash was developed. ... characteristics show the feasibility of industrial applications of fly ash for the production of ultra-lightweight ceramsite, which could not only produce economic benefits, but also ...
Yang et al. (2022) successfully prepared a low-density ceramsite proppant by utilizing a mixture of 30% water-based drilling cuttings and 70% bauxite after sintering …
Municipal sludge is a solid waste material, and resource utilization is the optimal way to dispose of this material. The amount of municipal sludge produced in China is large, and it can be used in the preparation of ceramsite. The content of Al 2 O 3 in drinking water treatment sludge is significantly higher than that in wastewater treatment …
The non-sintered ceramsite produced under the best experimental raw material ratio is shown in Fig. 12. From Fig. 12 ceramsite (a), the surface is low smoothness and lead-grey. However, the ceramsite (b) section in Fig. 12 is gray-white and has different sizes of tiny pores. There are honeycomb-shaped pores that are not …
DWTR based ceramsite also had relatively high specific surface area (22.1-50.5 m 2 /g) and could adsorb Cd, Cu, and Pb from solution. Overall, based on appropriate management, DWTR can be recycled as the main ingredient in the production of ceramsite for water environment remediation.

High-strength ceramsite was prepared from red mud, fly ash, and bentonite without any other chemical additives by a two-stage sintering process.
The ceramsite was prepared by using Bayan Obo tailings and blast furnace slag of Baotou Steel as the main raw materials and coal gangue as pore-forming agent, …
As can be seen from Table 1, the main chemical components of CFB fly ash and sludge are SiO 2 and Al 2 O 3, so they can replace clay as raw materials of sintering products.The contents of CaO and SO 3 in CFB fly ash are much higher than those in PC fly ash (CaO and SO 3 contents in PC fly ash are about 5 % and 1 % respectively [12], …
Most of the existing research focuses on the high-temperature preparation of sintered ceramsite, and there are few studies on the production and performance of non-sintered ceramsite. This research aims to reuse IMSWA and propose a new method for preparing non-sintered ceramsite that is safe and has low energy consumption.
A pilot study was conducted to produce high performance green ceramsite by using sewage sludge, fly ash and silt. According to the theory of Riley, the proportions of raw materials were chosen to perform the sintering experiments. Thereby, the optimum proportion of sludge, fly ash and silt and sintering parameters were determined. The …
Abstract. High-strength ceramsite was prepared from red mud, fly ash, and bentonite without any other chemical additives by a two-stage sintering process.
This study aimed to assess the feasibility of using red mud and waste sawdust for the production of ultra-lightweight ceramsite. The obtained results showed …
The color of AAs changes with the color of the binder and the hardening process [60][61][62]. For instance, fly ash aggregates were dark in color due to fly ash's dark color, and the aggregates ...
Another advantage of using sawdust as raw material for ceramsite production is that the residual hydrocarbons can supply additional energy to the firing process. The hazardous elements are effectively immobilized by the glassy phase in the sintering process, which implies that the red mud based ceramsite is a safe building …
The use of ceramsite to construct filtration systems (e.g., biofilters) is a common method for water treatment. To promote such applications, the development of low-cost, high-performance, and environmentally friendly ceramsites has received increasing attention from scientists, and a critical step in the development is the …
