Natural hydraulic lime mortars - The effect of ceramic residues on physical and mechanical behaviour

摘要: Abstract In the past, it was common use of ceramic residues as a pozzolan and/or aggregate in air lime mortars and concrete. Nowadays, incorporating is one ways to increase sustainability construction sector introduce some benefits properties those mortars. Ceramic were collected from several industries, namely bricks, roof tiles pots production, milled laboratory incorporated natural hydraulic (NHL) Two distinct groups prepared, with two different proportions, samples produced. A group volumetric proportion part NHL three parts (1:3) percentages replacement by each (0, 20 40% volume) second four (1:4) 0 30% prepared. Their behaviour analysed determining its after 28 days curing. The incorporation led an open porosity, capillarity water absorption vapour permeability but also dynamic elasticity modulus mechanical strengths. This more significant for higher percentages. these seems appropriate new renders plasters caution must be taken concerning moisture migration, when used rehabilitation.
