Abstract

The study outlined in this paper investigates the addition of Sugar Cane Bagasse Ash (SCBA) with cement to improve the mechanical and durability properties of compressed earth blocks. Initially, the chemical composition of the SCBA material was characterized by x-ray diffraction, particle size and morphology. Prototype compressed earth blocks were made using a variety of brick soils mixed with sand, cement and SCBA. These blocks were subjected to a variety of different tests to ascertain their mechanical and durability properties. The test results, outlined in the paper, indicate SCBA can be used together with cement as an effective stabilizer in compressed earth blocks. The blocks made with soil, 5% of the sand replacement by cement and SCBA obtained the best results in dry compressive strength at 7 and 28 days (112%; 159%), respectively when compared with the reference samples (soil and sand) and the values increased 25% when compared with the Brazilian Standard minimum performance requirements. In addition, the blocks had water absorption values 30% less than maximum values recommended by Brazilian Standard. The use of SCBA can reduce the environmental impact of masonry unit production, while meeting the current performance requirements.
