Diseño de adobes estabilizados con emulsión asfáltica

Abstract

Making adobes in the city of Cuenca, it is made with sand, silt, clay, water and straw, in some cases this traditional composition brings problems such as low moisture resistance, early erosion, shrinkage, etc., decreasing behavior mechanical material. Therefore we decided to use the asphalt emulsion as a stabilizer as combined with the mixture of mud, improved moisture resistance, prevents premature erosion and consequently improves their mechanical behavior.

This study was conducted in three phases. As a first phase evaluation of soils in the study area (Sinincay and bathrooms), where field tests and laboratory as performed was performed: sieve analysis, consistency limits, to accurately determine soil types and whether they are fit or for the production of traditional bricks and compressed earth blocks (BTC). In the second phase after validating soils determined, the mix design asphalt emulsion by adding different doses (2.5%, 5%, 7.5% and 10%), for the manufacture of bricks stabilized. Finally in the third stage was subjected to laboratory tests, determining the compressive strength, bending and absorption, for comparison with traditional bricks.

The results show that the addition of the asphalt emulsion enhances properties (compression, bending and absorption) with respect to the unstabilized bricks, these improvements are acquired by the effect of this addition. In conclusion the asphalt emulsion stabilized adobes are more resistant than traditional adobes.
