| Abstract | The role of superplasticizer in improving the quality of ferrocement was studied. Only one kind of superplasticizer was used in the study. Its dosage was changed from 0 to 1.0% of cement by weight in five steps. For each dosage of the admixture mix proportions of ferrocement mortar suitable for hand plastering application was determined by trial and error method for two and six mesh systems. The efficacy of superplasticizer in improving the workability of ferrocement mortar was assessed referring the results, Ease of compaction of superplasticized mortars under vibration was also examined using a specially made apparatus and a practical method to judge the workability was proposed. The effects of the use of superplasticizer on the hardened properties of ferrocement were examined by performing compressive, flexural and tensile strength tests, shrinkage test and impact test. Following are the main findings: 1. Mortars of adequate workability can be produced at remarkably low water-cement ratios by increasing the dosage of superplasticizer. However, there is a limit of the dosage beyond which no remarkable reduction in water content can be attained. 2. Strength of ferrocement is generally improved by the use of super plasticizer, although the degree of the improvement changes de pending on how effectively the increased strength of ferrocement mortar can be utilized in carrying the externally applied load. 3. Shrinkage of superplasticized mortar is equal to or lower than that of the plain mortar .. |
