A study on the production of adobe with the addition of silica fume

In this study, usability and resistance of silica fume in the manufacture of adobe by mixing silica fume in certain proportions with the material used in the manufacture of adobe was investigated. For this purpose, a certain amount of cement with no or some silica fume content was added to adobe. Three bricks were prepared with each of the cement added mixtures containing 0, 5, 10, and 15% (wsilica fume/wcement) silica fume. The prepared samples were tested to determine compressive strength, water resistance, and wind resistance. For the wind resistance tests, the bricks were painted with either plastic paint or lime. The results of the experiments showed that the silica fume substitution can be said to increase compressive strength and water resistance. However, the wind resistance values were not changed in the samples painted with plastic paint. The samples painted with lime showed visible capillary cracks, and partial spills occurred. -
