Study on Mechanical and Durability Properties of Ternary Blended Hybrid Fibre Polymer Concrete with M30 Grade
SK. Shahina | M. Srinivasarao
Abstract: Over the past several decades, extensive research work is in progress throughout the globe in concrete technology in finding alternative materials which can partially or fully replace ordinary Portland cement (OPC) and which can also meet the requirements of strength and durability aspects. Among that many alternative materials tried as partial cement replacement materials, the strength, workability and durability performance of industrial by products like flyash, blast furnace slag, silica fume, metakaolin, rice husk ash, etc. , now termed as complimentary cementitious materials (CCM) are quite promising. Subsequently, these have led to the development of binary, ternary and tertiary blended concretes depending on the number of CCM and their combinations used as partial cement replacement materials. In this report Slump, water absorption, compressive strength, split tensile strength, flexural strength and durability tests were conducted on concrete to investigate the possible use of ternary blended (cement+ silica fume+ GGBS) and hybrid polymers (polypropylene+ polyester fibre) as partial replacement for cement. Ordinary Portland cement (OPC) was replaced with 5 %, 10 %, 15 %of silica fume and 10 %, 20 %, 30 %, of GGBS and 0.4 %, 0.6 %, 0.8 % of polypropylene and 1 %, 1.2 %, 1.4 % of polyester. The cubes, cylinders and beam samples were water-cured and tested to determine their compressive strength at 7, 28 and 56 days. The results obtained showed that workability increased as percentage replacement of cement with silica fume and GGBS increased and also replacement of hybrid polymer is also increased the strength. The results of the compressive, split tensile strength and flexural strength revealed that concrete containing 10 % silica fume, 20 % GGBS and 0.4 % polypropylene and 1.2 % polyester increases and later on decreases for 7, 28 and 56 days. The durability studies can show that how the structure will react for the acid rains. Here the project will be done for two type of acids alkaline acid (H2SO4) and nitric acid (HNO3). The durability studies are done for 30, 60 and 90 days. It shows good result for ternary blended hybrid fiber polymer concrete. It can resist the structure form the environmental reactions like acid rains. Regression analysis is also done in this present study.
