Mold growth and moss growth on tropical walls

Abstract

The tropical climatic condition is the worst climate condition for building materials [1] [2] [3] [4]. Because, the tropics consist of rain, sun, high humid wind etc. [5] [6] [3]. The idea of the wall and roof are to protect human beings from these environmental constraints [4] [5] [6]. Hence, the capacity confronts those environmental constraints by the roof and wall are very important [7] [8] [9]. Not only environmental constraints but also there are other effects due to those environmental constraints such as weather degradation, scaling off the materials, natural decay, mold growth and moss growth. Molds can be found everywhere and can grow on any material in the presence of moisture. The growth of the mold is due to the pores. When the pores land on building materials they start to reproduce all over the material. Mold can be found in indoor climate as well as the outdoor climate. But the most dangerous mold can be found in indoor produced series of health problems due to a particle size of the mold [10].

Moss growth is subject to outdoor environments except in case of a water leak, which can be found in indoor climates. Moss growth is a common phenomenon in tropical climatic conditions. Moss growth is accelerated due to the rainy weather and stabilized by the materials property. For instant moss, brick is easily subjected to moss growth.

The effect and the growth rate of mold and moss are not properly studied in tropical climatic conditions (See Table 1). Tropical climatic condition is the most favorable climate for mold and moss growth. Therefore it is essential to understand the causes of mold and moss growth in tropical walling Material.
