Evaluation of the Properties of Adobe Blocks with Clay and Manure

Abstract

The development of new building materials that meet technological, economic, and environmental criteria has been highlighted in recent decades, especially regarding the use of alternative raw materials or new production methodologies. In this context, the objective of this project was to promote the development of adobe blocks using clay and manure, contributing to the sustainable development of the construction sector due to the use of adobe blocks, produced by the raw earth technique. Initially, the raw materials were characterized through chemical composition by XRF, mineralogical composition by XRD, granulometry, and Atterberg limits. Later, adobe blocks were produced manually, measuring 20 × 10 × 8 cm3, using three dosing techniques: (i) blocks with clay and manure; (ii) blocks with clay, sand and manure; and (iii) blocks stabilized by Portland cement and hydrated lime. The tests evaluated were compressive strength, water absorption, and durability. The characterization results of the raw materials show that the material used in the research are suitable for production of adobe blocks. The mechanical parameters prove a disadvantage of adobe blocks: their low resistance. Even so, the results with the use of adobe improve the strength of the material, due to the solidification of the adobe structure. In addition, the use of stabilization, mainly Portland cement, allows the results obtained in the research to be compatible with other published articles. Thus, it is concluded that the use of manure and stabilization, such as Portland cement, improve the mechanical behavior and stability of the blocks, which increases the durability of the material.

Evaluation Methods for Traditional Houses in Dobrogea

“…The studies carried out on unfired clay bricks indicate a maximum compressive strength of 3N/mm 2 , most of the times around 1.5N/mm 2 . The tensile strength is estimated at a value of 3% of the value of the compressive strength [1] [5] [6]. Taking into account all the above as well as the peak value of the design acceleration of the area, the R3 indicator defined as the ratio between the capacity of the structure and the value of the basic seismic force has a maximum value of 60, which means that the building falls into the RsII seismic risk class.…”

Investigação Da Resistência a Compressão De Resina Epóxi Modificada Com Cardanol

“…Nos dias de hoje cada vez mais se tem uma maior preocupação com as questões ambientais, sendo buscado dia após dia alternativas que agridam cada vez menos o meio ambiente e que ao mesmo tempo seja viável financeiramente [1,2,3]. Com isso a utilização de materiais naturais no lugar de materiais sintéticos vem se tornando cada vez mais comum, materiais esses que podem ser cultivados com muito mais facilidade sem gerar impactos negativos ao meio ambiente ou também que pode ser reaproveitado de materiais que normalmente seriam descartados que é o caso do LCC [4,5,6].…”

Análise Do Uso De Aditivo Antibolhas Na Confecção De Compósitos Particulados De Matriz Epóxi

“…O desenvolvimento de materiais sustentáveis utilizando resíduos tem ganhado destaque permitir maior sustentabilidade. Esta dá um destino mais adequado a resíduos que seriam descartados e minimiza o uso de recursos [1][2][3]. O uso de resíduos como fase dispersa de compósitos particulados tendo sido estudado para aplicações diversas, que vão desde materiais para uso doméstico a industrial [4][5][6].…”
