Abstract
Ferrocement is made of cement mortar reinforced with steel wire mesh that is spaced close to form a thin section with high serviceability. The present study investigates the performance of ferrocement mainly focused on the durability properties. The structures are needed to be durable in order to ensure that the service life intended is achieved. To evaluate the durability criteria of the ferrocement, series of cubes and cylinders were casted in this experiment using a mortar mix of ratio 1:3 & water cement ratio of 0.40 was adopted. The curing period adopted were 28, 56, & 90 days. The impact resistance of the ferrocement was determined in accordance with the ACI 544.2R-89. After performing the Impact Test, the energy absorbed was observed to be 5.13, 5.40 & 5.58 Joules for 28, 56, and 90 days respectively. Water Absorption test was performed in accordance with ASTM C 642, to determine the porosity of the ferrocement. After performing the test, it was observed that the average percentage of absorption was 5.89%, 5.41%, & 5.53% for 28, 56, and 90 days respectively. The carbonation resistance of concrete is an important parameter which is needed to be measured to check corrosion of reinforcement occurred by Carbon di Oxide. The results of carbon penetration measured after the following exposure periods: 56th, 63rd, and 70th day were 4.9mm, 6.08mm & 8.2mm respectively.
