Solo cimento: avaliação econômica da utilização de camada cimentada para reforço de fundações superficiais.

Abstract

Soil-cement is one of the possibilities of soil use for the production of buildings. The mixture of soil and cement, properly dosed and compacted, acquired resistance and presents durability compatible with the necessary criteria for the construction of buildings. The present work is aimed at the analysis of soil improvement with cement based on shallow foundations. Solution adopted in the construction of the technical school of Campina Grande. The study focused on the dimensioning of the surface foundations from the geotechnical profile of the soil, as well as the investigation of the natural and improved soil bored capacity, through calculation methods obtained in the literature. Because the soil-cement layer was too thin, the resistance difference of the natural soil and the soil-cement was practically nil, which resulted in a cost of running a foundation in natural soil less onerous than in soil improved with cement.
