Mechanical Properties of Concrete with Coconut Shell and Fibre as Additives

Sustainability is a key in modern construction scenario. Even when the construction industry underwent a revolution in terms of equipment and materials used, the resultant impact on environment skyrocketed. This leads to the adoption of more sustainable approaches in construction like using coconut byproducts such as coconut fibre and shell as additives in concrete. Coconut fibre is abundantly available material which makes it a viable reinforcement material in concrete and the same goes for coconut shell which can be used as a partial replacement for conventional aggregate. This can further act as a new source of income for the coconut producers who get the benefit of the new demand generated by the construction industry. It is also an effective method of disposal of coconut husks and shells and thus reduces their negative impact on the environment. This project aims at studying the variation of strength of coconut fibre reinforced concrete (CFRC) with different percentages of coconut fibre (0.5%, 1%,1.5% and 2% by weight of cement), coconut shell aggregate concrete by replacing coarse aggregate with different percentages of coconut shell ( 15%, 30% and 45%) compared with that of conventional concrete. The optimum percentage of both fibres to be added and coconut shell to be used is determined by analyzing the strength aspects such as flexural, compressive and tensile strength. This project also includes the investigation on the mechanical properties of CFRC with coconut shell aggregate by incorporating coconut fibre and shell together in concrete matrix.

There is no doubt concrete is most useful thing in construction industry but it has a negative impact also, just like a coin has two faces. Raw materials used in manufacturing of concrete affects the environment in one or the another negative way. Like manufacturing of cement produce carbon dioxide whereas the production of aggregates adds dust to the environment. Production of coarse aggregates also impact the geology of the area from they were extracted. A step taken in this direction is the use of waste products along with or in replacement of cement. Many of these materials are already in use, like silica fume, fly ash etc. In this study, plastic coarse aggregates were used in place of natural coarse aggregates. Plastic aggregates were produced by little processing of waste plastic. Plastic is the biggest threat to the environment, and it is affecting the environment rapidly. Some recent studies show that it can be used construction industry due to some of its properties like inert behavior, resistance to degradation etc. Also use of waste plastic can help in reducing plastic waste Various experiments were performed to test the mechanical properties of the concrete with plastic coarse aggregates. Concrete was prepared using plastic coarse aggregates in varying proportions of 0, 2.5, 5, 7.5 and 10%

Suitable Alternative

Concrete is the most widely used construction material today. The constituents of concrete are coarse aggregate, fine aggregate, coarse aggregate and water. Concrete plays a major role in the construction industry and a large quantum of concrete is being utilized. River sand, which isone of the constituent used in the production of conventional concrete, has become expensive and also a scarce material. In view of this,the utilization of demolished aggregate which isa waste material has been accepted as building material in many countries for the past three decades. The demand of natural sand in the construction industry has increased a lot resulting in the reduction of sources and an increase in price. Thus an increased need to identify a suitable alternative material from industrial waste in place of river sand, that is eco-friendly and inexpensive construction debris i.e fresh concrete being extensively used as an alternative to the sand in the production of concrete. There is an increase in need to find new alternative materials to replace river sand so that excess river erosion is prevented and high strength concrete is obtained at lower cost. One such material is building construction debris: a by-product obtained during construction and demolition waste. An experimental investigation is carried out on M 25 concrete containing debris during construction in the different range of 20%, 30% & 40% by weight of sand. Material was produced, tested and compared with conventional concrete in terms of workability and strength. These tests were carried out on standard cube of 150×150×150 mm and beam of 700×150×150 mm for 28 days to determine the mechanical properties of concrete.

Sisal Fibers

Abstract Concrete is one of the most important material that is used in the construction industry all around the world. A larger part of the capacity in concrete is generally employed by the coarse aggregate. Due to the tremendous use of coarse aggregate in the construction industry the material is getting degraded. In order to preserve the natural material, we are in search of an alternate material that can be used in concrete instead of the original one. So in this research work a try has been attempted to study the mechanical behaviour of light weight concrete when we use coarse aggregate as waste coconut shell inside concrete. To improve the strength of concrete we also use the sisal fibers in various proportions ranging between 1% to 5% in accordance to the binder weight. After the mechanical properties tests such as the compression test, spilt tensile strength, flexural test, modulus of elasticity test, impact resistant test were conducted finally it was concluded that there was increment in the compression strength up to 5%, tensile strength was increased to 17% elastic modulus to 7% when the fiber content used was 3%. Thus with the use of these waste materials it was found that the concrete's strength gets increased and it leads to the formation of sustainable concrete thus reducing the pollution in the environment.
