Use of Incinerated Sugarcane Filter Cake as a Material in Producing Cellular Lightweight Concrete

Abstract

This study investigated the properties of cellular lightweight concrete (CLC) incorporating incinerated sugarcane filter cake (FC) as a substitute for Type I Portland cement (OPC) at replacement percentages of 0%, 5%, 10%, 15%, and 20% by weight. CLC was maintained at a density of 1,000 ± 50 kg/m3 and a constant water–binder ratio of 0.5 was used for all mixes. Tests for density, flow behavior and setting time were carried out on fresh concrete mixes and tests for compressive strength, flexural strength, indicated that calcium oxide (CaO) is the main component of sugarcane filter cake (FC). The particles of FC are irregular in shape and most particles have both rough and smooth surfaces. CLC containing suitable amount of FC exhibited increased flowability. The compressive strength and flexural strength of CLC decreased, whereas its shrinkage and water absorption increased as a result of increasing the percentage at which FC was used to replace OPC. The results suggested that it is possible to use FC in the production
of CLC according to the Thailand Industrial Standard TIS-2601-2556 (cellular lightweight concrete).
