In order to assess local materials and help reduce construction costs and energy consumed, rice husk ash and banana fiber have been used as additives to stabilize compressed earth blocks (CEB). The main objective of this thesis is to contribute to the improvement of technology for the manufacture of stabilized CEBs with regional natural additives for the construction of houses, with low energy and environmental costs and that can be promoted through self-construction. To achieve this, the influence on the compressive strength and flexural strength of the CEB was investigated, using the same type of soil, keeping the compaction pressure constant, and using lime as stabilizing agents (in constant percentage), with different proportions of rice husk ash and banana fiber. In the manufacture of the CEB a constant volume manual press was used, applying a constant compaction pressure, and as additives the lime (5%), four different contents of rice husk ash (2.5%, 5%, 7.5% and 10%) and two different contents of banana fiber (0.175% and 0.25%). The results show an increase in the resistance to compression and flexion of the CEB when it is added, within certain limits, lime, rice husk ash, and banana fiber; in fact, the compressive strength of the CEB obtained by adding different combinations of natural additives is comparable to those required by some building codes with soil for the CEB. The results also show that if the contents of the rice husk ash and the banana fiber exceeds these established limits, their influence is detrimental to the resistance characteristics of the CEBs. Additionally, the research shows that the addition of banana fibers increases the ductility of the CEB compared to the fragile behavior of the blocks manufactured without fiber. In general, the work concludes that CEBs stabilized with rice husk ash and banana fiber have the adequate strength properties for use as construction material for the self-construction of housing, especially for developing countries, among they are Peru, particularly in the San Martín Region, due to the abundance and low cost of the selected additives. Another purpose of this thesis is to motivate the need for a standardized framework for the production of BTC and for this a proposal was developed for the Technical Standard for the technical specifications and production of the BTC.
