Influence of tea waste concentration in the physical, mechanical and thermal properties of brick clay mixtures

The sustainability of raw materials used in construction industry consumed large quantities of material has great importance. The use of pore-makers in the brick production is reducing the consumption of clean clay resources as well as lightness of the baked brick body. Many organic or inorganic additives have been used as pore-making in brick production for improving thermal performance. In this study, tea waste (TW) were used at different concentrations in the brick clay mixtures to examine its effects on baked brick properties. In addition to micro-structure investigations, physical, mechanical and thermal properties of bricks produced were investigated. It is concluded that tea waste additive up to 10% in brick body can be used for structural application and isolation while ratios more 10% tea waste additive for only isolation purposes. Tea wastes can be used as a pore-making additive in the brick production. (C) 2019 Elsevier Ltd. All rights reserved.
