Article Preview

In civil construction, β-hemihydrate pastes have been used as decorative ornaments, plasterboards, dry-wall and renderings. The application procedure of β-hemihydrate pastes for rendering generates large amounts of waste due to its hydration kinetics. Waste production also occurs due to the technique of preparation and application of this material. It is essential to minimize gypsum waste. The aim of this work was to quantify the amount of gypsum waste produced by the process of using it as renderings. It was observed the influence of workers applying pastes rendering on gypsum waste production. The application process of plaster renderings was followed measuring the waste generated and the time for finishing the process was also observed. Results pointed out waste production values in the range between 16% and 47%. The application technique influences the amount of waste production.
