Bazalt beton üretiminde agrega olarak tercih edilen ancak üretimi esnasında yan ürün olarak yüksek miktarda atık bazalt tozu malzemesi ortaya çıkaran bir kayaçtır. Bu atık malzemenin geri dönüşümüyle çevreye ve insan sağlığına verdiği zararın azaltılmasının yanında çimentoyla ikame edilmesi harç (beton) hammadde maliyetinde bir miktar düşme sağlayacaktır. Çalışma kapsamında kontrol serisi ve %5, %10, %15, %20 oranlarında bazalt tozu çimento ile ikame edilerek toplamda 5 seri harç numune üretilerek taze ve sertleşmiş harç deneyleri gerçekleştirildi. Taze harç deneyi olarak kıvam tayini, sertleşmiş harç deneyi olarak basınç, eğilme, yarmada çekme ve geçirimlilik deneyi olarak basınç altında su işleme derinliği deneyleri yapıldı. %10 ikameli seride basınç dayanımında yaklaşık olarak %8 oranında artış elde edilirken, eğilme dayanımında ise %15 ikameli seride önemli bir artış elde edildi. %10 bazalt tozu ikame oranına sahip seride basınç altında su işleme derinliği düşüş göstererek olumlu bir katkı sağlamaktadır.
Basalt is a stone that is preferred as agrega in concrete production, but during production as a side product high amounts of waste basalt powder material. In addition to the reduction of the damage to the environment and human health by the recycling of this waste material, the cement storage will result in a slight decline in the cost of the raw material. In the framework of the study, a control series and a basalt powder cement of 5%, 10%, 15%, 20%, produced a total of 5 series of shell samples and performed fresh and solid shell trials. Toughened Laminated Safety Glass Tests were conducted under pressure as a test of slurry, slurry, drill, and water processing depths as a test of hardening, slurry, slurry, and slurry. The 10 percent resistance to pressure series has been increased by about 8 percent, while the 15 percent resistance to inclination series has been significantly increased. Basalt powder with a 10% basalt powder resistance contributes to a positive contribution by showing a decrease in the water processing depth under pressure.
Basalt can be used as aggregate in concrete however, very fine waste basalt powder is released as by-product during aggregate production. The hazardous effect of this waste material on human health and environment can be diminished while using basalt powder as cement replacement material. In this study, reference and basalt powder added mortars were casted. Basalt powder was replaced at different percentages by weight of cement such as 5%, 10%, 15% and 20%. Workability (flow-table), compressive strength, flexural strength, splitting tensile strength and permeability tests were performed at fresh and hardened state of mortars. In the 10% incremental series, an increase of approximately 8% was obtained in the compressive strengths and a significant increase in the flexural strength in the 15% substituted grades was obtained. A significant decrease was obtained at permeability of mortar with 10% basalt powder replacement as result of having denser structure at paste phase.
