Lightweight aggregates are widely used in renders to obtain low densities and better workability. This type of aggregate requires higher than normal water:cement ratios, especially in renders involving the addition of alkyl celluloses or modified starches. This paper reports the effect of some lightweight materials (expanded perlite, expanded glass, hollow micro-spheres and expanded polystyrene) on density, fluency, sorptivity, water absorption and mechanical strength, all of which play an… CONTINUE READING
