This present study investigated the crushed ceramic waste utilisation as sand replacement in solid mortar bricks. The percentage of crushed ceramic waste used were 0% (CW0), 10% (CW10), 20% (CW20) and 30% (CW30) from the total weight of sand. The dimension prescribed of mortar bricks are 215 mm x 102.5 mm x 65 mm as followed accordance to MS 2281:2010 and BS EN 771-1:2011+A1:2015. Four (4) tests were conducted on mortar bricks namely crushing strength, water absorption, compressive strength of masonry units and thermal comfort. The incorporation of ceramic waste in all designated mortar bricks showed the increment of crushing strength between 23% and 46% at 28 days of curing and decrement water absorption between 34% and 44% was recorded corresponding to control mortar bricks. The prism test of masonry units consists of mortar bricks containing ceramic waste indicated the high increment of compressive strength at about 200% as compared to mortar brick without ceramic waste. The thermal comfort test of ceramic mortar bricks were also showed the good insulation with low interior temperature. Therefore, the ceramic waste can be utilised as a material replacement to fine aggregate in mortar brick productions due to significant outcomes performed.

The Impact

Abstract During processing and transport, the ceramic industry generates big amounts of waste. In order to limit the number of landfills and to minimise consequences of such waste that is clearly noxious for the environment, this industry remains under great pressure to find effective recycling methods for its waste and by-products. What is more, given the limited resources of traditional aggregate, energy savings and protection of the environment, the construction industry is seeking for new sources of aggregate. For this reason, ceramic waste is increasingly frequently used as coarse and fine aggregate, both in mortars and in concrete mixtures. The goal of studies presented in the paper was to analyse the impact of recycled ceramic aggregate on the frost and salt spray resistance of stucco mortar used in the construction industry. Mortar recipes also contained admixtures that modify properties of the mixture and of the hardened product, such as copolymer of vinyl acetate and methylcellulose with a hydrophobic admixture. Elementary testing was performed related to mechanical and physical parameters of mortars. Among others tests were carried out of compressive strength and flexural strength, a determination was made of density, open and total porosity, absorbability, resistance to salt spray corrosion and frost resistance after 25 freeze–thaw cycles of samples. Replacement of sand by recycled ceramic aggregate causes a change in physical parameters of mortars. It has a positive impact on strength parameters of mortars with concurrent reduction in absorbability and capillary action. Testing of mortar with the addition of ceramic aggregate has proved better frost resistance and resistance to salt crystallisation as compared to mortar to which sand had been added.
