Sustainability in construction works: Reuse of sludge from tunnel boring in lime mortars

Abstract: This study is based on reuse of sludge fromtunnel boring for themanufacture of mortarswith calciumhydroxide and their possible application in construction. Three samples have been tested with different percentages of sludge fromtunnel boring obtaining high consistency. This percentagewas used to produce two types ofmortars, one with limestone-type aggregates and the other with siliceous-type material, which were then subjected to compression and flexural tests. The analysis shows that the use of these sludge, with calcium hydroxide and siliceous-type aggregates, helps to improve the mortars’ properties and increase their flexural strength to values above 4 MPa, which could be reused as a coating for underground work and road construction as long as its complies with the standard.
