The aim of this study is to search some mechanical features of polypropylene fibre mixed adobe. As fibre additive polypropylene, in proportions of 0%, 5%, 10%, 15%, soil with 26% clay and 7 kg straw per cubic meter were mixed and mixture with adobe was prepared. As a result the compressive strengths of the polypropylene fibre mixed samples were determined as 40 kgf/cýrf in %0, 26.55 kgf/cm in 5%, 31.62 kgf/cm2 in 10%,37.35 kgf/cm2 in 15%; tensile strengths as 13.76 kgf/cm2 in 0%, 45.80 kgf/cm2 in 5%, 46.90 kgf/cm2 in 10%, 47.20 kgf/cm2 in 15%; heat conduction values as 0.58 kcal/mh°c in 0%, 0. ...Более
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
As the urban population increases and the level of social life advances, the amount of wastewater originating from houses, institutions and industries increases as well. It is necessary for the infrastructure systems in settlements to be sustained under healthy conditions. Since the subsequent repair of infrastructure systems is difficult, appropriate selection of the materials used in these systems is of importance. Concrete pipes are widely used in sewerage systems. In the present study, it was aimed to improve the biological corrosion resistance of concrete pipes via coating with various ma ...Более
Millions of tires are discarded every year. Disposal or recycling-reusing of waste tire rubber has become a big environmental problem in the world. In this study, it was aimed to determine the freezing-thawing, impact resistance, compressive strength and capillary water absorption rate, when the granulated waste rubber parts are used in the non-load-bearing concrete. Granulated crumb rubbers obtained from waste tires were used at two different grain diameters of 1 and 2 mm as the maximum value. A total of 9 different series were prepared, one of them being the control group and the others bein ...Более
This paper introduces an experimental research about the influences of the curing type on accelerated carbonation, capillary water absorption and permeability of a range of different self-compacting lightweight concrete (SCLC) mixtures in comparison with those of chosen conventional vibrated lightweight concrete (LC) and self-compacting concrete (SCC). Seven different concrete compositions are considered: four SCLC, two SCC and one LC mixtures. All of the SCLC mixtures and one of the SCC and one LC mixture with a constant powder dosage of 550 kg/m(3) was designed to be containing 440 kg/m(3) o ...Более
