Bu çalışmanın amacı; manyetize edilmiş suyun,
lifli ve lifsiz reaktif pudra betonların (RPB) basınç ve eğilme dayanımı
üzerindeki etkisini incelemektir. Farklı manyetik alan şiddetleri manyetik su
üretimi için kullanılabilmektedir. Bu çalışmada; 0.8-1 ve 1.2 Tesla
şiddetindeki üç farklı manyetik alan şiddeti seçilmiştir. Manyetik su üretimi
için farklı manyetik alan şiddetlerinde bekletme süresi 20 dakika olarak sabit
alınmıştır. Elde edilen sonuçlar incelendiğinde; normal su kullanımı yerine
manyetik su kullanımı, 7 ve 28 günlük basınç ve eğilme dayanımlarının artmasını
sağladığı görülmüştür. Ayrıca manyetize edilmiş suyun, RPB’lerin basınç ve
eğilme dayanımına olumlu etkisi olduğu ve dayanımı artırmak için en verimli
manyetik alan şiddetinin 1 Tesla olduğu tespit edilmiştir.

The Effect of Magnetized Water on Compressive and Flexural Strength of Reactive Powder Concretes

Öz

The aim of this study is to
investigate the effect of magnetized water on compressive and flexural strength
of reactive powder concrete (RPC). Different magnetic field intensities can be
used for magnetic water production. In this study, the effects of three
different magnetic field intensities i.e. 0.8-1 and 1.2 Tesla have been
assessed on compressive and flexural strength of RPC. The magnetic water used for
manufacturing of the specimens was exposed to magnetic fields for 20 minutes in
all mixes. When the results are assessed, it can be concluded that using of
magnetic water instead of normal water causes increase in 7 and 28 days
compressive and flexural strength. In addition, it has been determined that the
most efficient magnetic field strength is 1 Tesla to increase the strength.
