| Abstract | ||
| This study involves the design of 24 mixtures of fiber reinforced magnetic reactive powder concrete containing nano Silica. Tap water has been used in mixing 12 of these mixtures, while the other 12 have been mixed using magnetic water. Nano Silica (NS) with ratios (1, 1.5, 2, 2.5 and 3) % were used. The results showed that the mixture containing 2.5%NS gives the highest compressive strength at age 7 days. Many different other tests were carried out, the results showed that the fiber reinforced magnetic reactive powder concrete containing 2.5% NS (FRMRPCCNS) has the higher bulk density, dynamic modulus of elasticity, ultrasonic pulse velocity electrical resistivity and lesser absorption than fiber reinforced nonmagnetic reactive powder concrete containing 2.5%NS(FRNRPCCNS). The percentages of increase for FRMRPCCNS are (1.6, 19.03, 7.89 and 19.28) % and the percentage of reduction is 55.7 % at 28 days respectively, as compared with FRNRPCCNS mixtures. | ||
