Recent years have brought a rapidly growing demand in the civil engineering field for durable structural material which is also plant life friendly. Concrete has sufficient durability but lacks such friendliness. Soil is sufficiently plant life friendly but lacks durability. This research presents durable structural materials which are plant life friendly: Some cementitious structural materials mixed with rice husk ash, the powder left after rice husks are destroyed by burning for example. There are at least three phases in a material’s life cycle: the production phase, the maintenance phase, and the disposal phase. These structural materials are designed to ensure good performance in all three phases; they are produced from an environmentally friendly by-product; they excel in permeability and water retentivity as well as in durability; and they decompose, causing only negligible damage to environments. Carbon dioxide emitted by burning rice husks was analyzed in the case of a power plant (cogeneration system) utilizing rice husks. These materials reduce carbon dioxide emissions by replacing cement with rice husk ash. This study will contribute to the low carbon societies.
