Abstract

Aerated concrete is a lightweight concrete due to its low density, this concrete is used as a construction material in nonstructural elements. Housing solutions are built around the world with this material. In Ecuador the use of this concrete is limited and in the city of Cuenca is little known; in the country there are about 3.8 million households living in inadequate conditions, although this material may be an alternative to construct houses as part of the housing solution.

Three types of aggregates were analyzed, these aggregates came from three different mines near the city of Cuenca and two types of foaming agents were studied.

This research was intended to obtain experimental results through laboratory tests, so that the results are reliable methodology of research (Statistical Inference), which from experimental design and experimental planning were able to confirm the reliability of the applied experiments.

In the absence of specific rules for the development of aerated concrete, tests with different materials from the area that are part of the mixture were made: aggregates, cement, foaming agents for various ratios of a/c, using as reference the INEN standards, ASTM and ACI.

In the process of testing the raw material was analyzed and the one with the best results were used in the experimental process. These results were obtained from analysis of physic-mechanical aggregates and foaming agent. In the process of making aerated concrete experiments were performed with 16 mixes to obtain results densities and resistances ranging from 1.73 to 1.96 g / cm3 and 1305 to 253 kg / cm2 respectively.

Finally, with the obtained results a behavioral analysis was made to obtain the conclusions and recommendations.
