Investigation of fungus growth and moss growth on different wall care putty materials along with different walling materials

Abstract

Cement and sand are two of the materials which are used in the infrastructure development and are also main components of masonry coatings. Nevertheless, negative impacts indicated by these materials are crucial. Cement production accounts for considerable amount of global CO2 emissions while sand mining activities disturb the natural equilibrium. However, cement and sand consumption can be considerably reduced by omitting wall plastering. In order to accomplish the requirement of smoothing the wall, application of wall care putty materials to an unplastered wall can be considered as a sustainable solution. This research study was conducted to investigate the fungus growth and moss growth on different wall care putty materials along with different walling materials. Four types of walling materials and ten types of wall care putty mixtures were selected. Fungus growth and moss growth were conducted in controlled environment to accelerate fungus growth and moss growth on wall care putty materials. Results of this study showed that wall care putty mixtures were not prone to fungus growth under tropical climatic conditions. Moss growth was present on wall care putty mixtures and there was an impact from the walling material to the growth of moss on the surface of putty application
