    The present study focuses on preparation of composite wall panels, reinforcing with three different pre-treated lignocellulosic material fibers - bagasse (B), paddy straw (PS), and banana stem (BS). Soil-based composite wall panels were prepared by mixing cement, laterite soil, and lignocellulosic materials in the weight ratios of 1: 1: 0.025. Morphological characteristics, water absorption, flexural strength, and thermal conductivity were tested in prepared wall panels after keeping at curing period of 28 days. The characterization results of molded wall panels indicate the variation of flexural strength as 1.85 - 4.05 MPa, percentage of water absorption as 14.7-20.2% and thermal conductivity as 0.131 -0.252 W/mk. The characteristics of some molded wall panels prepared in the present study were at a satisfactory level compared to the market available wall panels.

    Development of soil based composite wall panel using locally available laterite soils
    (Department of Materials Science and Engineering, University of Moratuwa., 2022-11) Samarasinghe, MMA; Gunathunga, WPS; De Silva, GIP; Fernando, TN; Abeygunawardana, AAGA
    This research focus on developing laterite soil-based composite wall panels by using soil cement mixture, reinforced with cellulose fibers from pretreated cornhusk. In this, effect of various laterite soils and cement proportions of the mixture on the properties of wall panels like flexural strength, water absorption and thermal conductivity were determined. It has been observed high Al2O3+Fe2O3 content, good particle size distribution, lower clay content of soil shows good performance of wall panel properties. Further, lowering the cement content of the mixture reduces the wall panel performance.
