Abstract


This article evaluates the physical and mechanical properties of a paving block with added ash from artisanal brick kilns in the city of Juliaca to reduce the environmental pollution generated by the ash. For this purpose, data and test results were collected at the GEOCONTROL laboratory in Juliaca. It was designed for a compressive strength of f’c=340 kg/cm2 for type II pavements, adding ash from artisanal brick kilns of 0%, 5%, 10%, 15% and 20% as a partial replacement of cement. Aggregates from the Cabanillas quarry, Portland cement type I and ash from artisanal brick kilns were used as raw materials for the mixture design. From the results obtained, it is concluded that the addition of 5% ash from artisanal brick kilns improves the compressive strength at 28 days of curing. It is important to mention that if the percentage of added ash from artisanal brick kilns increases above 10%, the resistance decreases. Finally, the dimensional tolerance and absorption of conventional paving blocks and additions of 5% ash from artisanal brick kilns meet the established criteria of NTP 339.611.

Keywords
