Pineapple fibre as an additive to self-compacting concrete

As concrete being widely used in the field of construction, the demand for the materials used is increased rapidly. To meet the growing demand it is necessary to use alternative materials to meet the requirements. The Pineapple leaf fibre (PALF) is a highly available material in larger quantity with lesser water content and higher fiber content which makes it as a desirable material as natural fibre. The workability characteristics of Self compaction Concrete (SCC) like flowability, filling ability, passing ability, resistance to segregation and bleeding of concrete were out by using slump cone, U-box, L-box, V- Funnel and J-ring test. The test result shows satisfactory results on the workability of SCC. The fresh and hardened properties of concrete were found at the ages 7 days, 14 days and 28 days for various addition of PALF and various replacements of granite powder with the fine aggregate. The addition of PALF has achieved maximum compressive strength and split tensile strength in all ages of concrete at PALF0.2. The replacement of granite powder with fine aggregate seems to be promising in achieving the maximum compressive strength and split tensile strength at the 10% of replacement.

Automated summary

With the widespread use of concrete in construction, there has been a rapid increase in demand for the materials used. To meet this growing demand, it is necessary to use alternative materials that meet the requirements. Pineapple leaf fibre (PALF) is a highly available material with low water content and high fiber content, making it an ideal natural fibre material. The workability characteristics of Self Compaction Concrete (SCC) were tested using various methods, and satisfactory results were obtained. The addition of PALF achieved maximum compressive strength and split tensile strength in all ages of concrete, while replacing granite powder with fine aggregate showed promising results at a 10% replacement rate.
