Abstract

The purpose of this research is to determine the variation in the compressive and flexural strength of compacted adobe by adding aloe vera gel in percentages of 0%, 1%, 1.5% and 2%. As we know in Cajamarca it is a material widely used in rural areas, so by adding aloe vera gel we seek to improve its mechanical properties knowing that it is easily accessible, low cost and does not produce environmental pollution. We studied the soil of the Pariamarca - Cajamarca quarry, determining its moisture content, granulometric analysis and consistency limits, in order to classify it, then modified proctor tests were carried out to obtain the optimum moisture content for the production of the standard adobe and the addition of aloe vera gel. Sixty-four adobes were made with the CINVA RAM machine, of which 32 adobes were tested in compression and 32 adobes in flexure. The hypothesis was that the compressive and flexural strength of adobe compacted with the addition of aloe vera gel increases up to 5% of its strength. The results were partially satisfactory, the addition of aloe vera gel in percentages of 0%, 1%, 1.5% and 2% in the compacted adobe, improves its mechanical properties, in compressive strength by up to 28.14% with respect to the value found for the standard sample (without addition), in flexural strength by up to 46.58% with respect to the standard sample (without addition), in flexural strength by up to 46. 58% with respect to the standard sample, presenting compression values of 32.69 kg/cm2, 38.58 kg/cm2 and 29.15 kg/cm2 (the latter not complying with the hypothesis) and flexural values of 6.19 kg/cm2, 7.09 kg/cm2 and 5.66 kg/cm2
