Study on shape-stabilised paraffin-ceramsite composites
High porosity of ceramsite is significant but opening distribution is also crucial for PCM incorporation. It is preferred to have interconnected, small pores/defects uniformly distributed inside of the ceramsite particles. This structure is better as PCM supporting material but poses challenges for ceramsite production.The production of ceramsite is an effective way to utilize sludge (He and Wang, 2019). The Chinese standard requirements for ceramsite are mainly construction materials (lightweight aggregates and their test methods-Part 1: lightweight aggregates, China's standard number: GB/T 17431.1-2010) and water treatment materials (artificialPreparation of ceramsite from municipal sludge and its

Ceramsite, as a member of artificial aggregate, is a lightweight particle with bulk density of lower than 1200 kg m −3, internal porosity, and ceramic surface [1,2].According to the bulk density, ceramsites are classified as general ceramsite (500–1200 kg m −3), ultra-lightweight ceramsite (300–500 kg m −3) and extra Template-free route to fabricate extra-lightweight ceramsite

4 Million m3/Year Shale Ceramsite Products Project of
China began to study ceramsite in 1956, mainly on sintered fly ash ceramsite, which formed production capacity in 1960s. Shale ceramsite production develops rapidly in Beijing, Tianjin, Heilongjiang, Inner Mongolia, Jilin, Yunnan, Xinjiang and other places. With the development of social economy, the construction industry has As shown in Fig. 1.5, the nickel production gradually increased from 330 in 2010 to 736 thousand tons in 2013 in China, with an average annual growth rate of more than 40%. Since 2014, the nickel production in China has decreased due to the overseas investment of Chinese enterprises in the construction of ferronickel production lines.An Overview of Nickel Utilization from Laterite Ore

Sustainability Free Full-Text Preparation of Ceramsite
Using dehydrated silt soil as a raw material to produce ceramsite for ceramsite concrete blocks is a promising approach from both environmental and economic aspects. In this paper, flocculant polyacrylamide (PAM) was investigated to dehydrate the silt, and the optimal dosage of PAM was found to be 0.8 mol/L. The dehydrated silt was Dredging sea mud produced during the coastal infrastructure construction has been gradually becoming an environmental problem in China. Making ceramsite is an attractive way to convert the waste sea mud to resources used for many industrial sectors. However, the imapct of preheating and sintering conditions on the ceramsite properties and the A Study on Ceramsite Production Using Dredging Sea Mud

Comparative life cycle assessment of two ceramsite production
Ceramsite was sintered using coal gasification slag, fly ash, construction spoils, and municipal sludge. The influence of the municipal sludge content on the ceramsite performance was studied by1. Introduction. Ceramsite is a porous material with the loose bulk density below 1.20 g/cm 3 or the apparent density below 2.00 g/cm 3 [1].Due to its high strength and low density, ceramsite is commonly used in construction materials, such as lightweight blocks, bricks and concrete [2], [3], [4].Generally, ceramsites are produced by the Preparation and characterization of ultra-lightweight ceramsite
