عنوان مقاله [English]
self-compacted concrete(SCC) is a concrete that can flow in the space between reinforcement without separation and compact only by their own weight. In this study, the effect of using silica fume, metakaolin, rice husk ash and fly ash with different ratios of 10% and 20% by weight of cement in self-compacting concrete containing magnetic water is concered. The fresh properties of self compacted concrete were's tested by means of slump flow, T50, V-funnel, L-box and visual stability index(VSI). The hardened properties were assessed, using compressive strength at the ages of 7 and 28 days. Also splitting tensile strength and water absorption test were assessed at the age of 28 days. In addition, concrete specimens were made using tap water and magnetic water, was passed through a magnetic field of 0.8 Tesla. The results show that pozzolanic materials are suitable in properties of self-compacting concrete containing magnetic water in terms of flowability and viscosity. Moreover, magnetic water can reduce the amount of superplasticizer, required for SCC, up to 45%. Also the results of hardened SSC show an improvement in mechanical and durability properties of concrete. The usage of silica fume with ratio 20% by weight of cement in self-compacting concrete containing magnetic water, increases the compressive and splitting tensile strengths by 48% and 35% respectively and decreases amount of water absorption by 55% at the age of 28 days
