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 eith ...Более
In this study, it was tried to obtain bearing concrete by using the pumice and perlite aggregates in certain proportions. Different cement dosages were used in every mixture poured with portland cement and portland composite cement, the 60% pumice and 40% perlite aggregates of which were kept stable. The silica fume was added as much as 10% of cement amount in mixture. Mixtures from 200 to 500 doses were made and poured with every type of cement. The prepared samples left to water cure and their 7 and 28 days compressive strengths were determined. The test results indicated that the mixtures p ...Более
