Areia de britagem de basalto como alternativa para substituição à areia natural na produção de pavers

Abstract

This work is justified by its contribution to sustainable development in the construction industry, by enabling the reduction of natural resource exploitation through the use of alternative materials, such as crushed basalt sand. The objective was to conduct a technical analysis of replacing natural fine aggregate sand with artificial crushed basalt sand in the production of pavers. The methodology involved the production and study of three concrete mixes, starting from a reference mix and using in the fine aggregate fraction 60% artificial sand and 40% natural sand, 70% artificial sand and 30% natural sand, and 80% artificial sand and 20% natural sand. The results indicated that all three mixes met the ABNT – NBR 9781/2013 standard, with the mix containing 70% artificial sand showing the best performance in terms of strength. It is concluded that replacing natural sand with artificial crushed basalt sand is advantageous, proving to be a viable and sustainable alternative for paver production.
