This paper presents a comprehensive study on the possibility of sewage sludge management in a sintered ceramic material such as a lightweight aggregate. Made from clay and sludge lightweight aggregates were sintered at two temperatures: 1100 °C (name of sample LWA1) and 1150 °C (name of sample LWA2). Physical and mechanical properties indicate that the resulting expanded clay aggregate containi...

In the present study, lightweight expanded clay aggregate (LECA) coated with iron oxide was investigated as a low cost sorbent to remove  from wastewater. Iron oxide coated LECA (IOCL) as a new sorbent was tested for its efficiency as  sorbent using operational parameters such as contact time, the initial pH of the solutions, and sorbent dosage concentration in batch systems. The adsorption cha...

Concrete is an essential element and widely used in various industrial construction works. However, concrete weak its specific gravity range of 2200 – 2500 kg/m3. Using lightweight aggregates one way to reduce the weight concrete. In Indonesia, availability coal fly-ash (CFA) easy obtain abundant, while utilization rate still low. To overcome this problem, CFA mixed with epoxy resin ...

Due to the low density of aggregates and longer mixing times, lightweight aggregate concrete (LWAC) is susceptible segregation aggregates. Several studies have proposed different methods estimate because affects strength durability in structures. Image analysis techniques become very popular for quickly analysing materials and, together with widespread use mobile applications, can make it much ...
