While, in the process of production, Portland cement and lime emits CO2, plaster emits molecules of water in the atmosphere. While the production of lime and cement Portland requires high temperature, plaster needs only 150~C. In spite of these environmental advantages, plaster is relatively little used in Brazil and in the rest of South America. An effort has been made to increase the consumption of this material in housing. In this work, a constructive system was developed using plaster blocks. This rationalized system looks for to reduce the manpower considerably, the times of execution and, consequently, the final costs of the construction. The basic components are three types of main blocks, and from these main blocks, sub-blocks are obtained, so that all the dimensions of the construction are achieved. All the dimensions of blocks, sub-blocks and construction are multiples of the base-unit, 10 cm, basic principle of the modular coordination. So, waste of material is avoided. The blocks developed and the constructions way are presented.展开更多
