The effects of using magnetized water in reactive powder concrete with different curing methods

Year: 2021

Type: conference-paper

Abstract: The effects of using magnetized water in reactive powder concrete (RPC) under various curing procedures was investigated. The RPC samples were separated into four groups, cured with three different curing methods compared to normal curing (lab conditions) as a reference procedure, these methods were; autogenous curing, submersion in warm water (35 °C) and curing by applying high temperature (70 °C) cycles. A magnetic water device was used to produce magnetic water for use in the RPC mix. Where, the intended water was moving with flow rate equal to 0.1 m3/hr. passing through a magnetic field with an intensity of 0.9 Tesla. This circulation process was used for 60 minutes to produce the magnetized water utilised in this study. Test results showed some improvements in the compressive, flexural and splitting tensile strength for RPCs cured with different curing methods The percentage increases for compressive strength for RPC mixes containing magnetic water. Where, the enhancing percentage reached 7.66, 8.43, 8.86, and 9.15% for normal curing, autogenous curing, warm-water, and high temperature curing respectively at 28 days. The high temperature curing method showed the maximum improvement in compressive strength, with up to 34.4, 30.6, and 28.52% increases at 7, 28, and 90 days, respectively.
