Abstract –

Wood carbon powder.

1.2 Cement

Concrete may be strong in compressive strength but it is weak to its tensile strength as it is having high load bearing capacity rather than the tensile strength. To increase different mechanical properties of concrete different types of materials are being used in present day market.

Ordinary Portland cement (OPC) of grade 53 was used, with composition and properties which fulfil Indian standard organisation requirements.

1.3 Water

The objective of this research is to investigate the potential use of Coconut Shell Carbon Powder (CSCP) as a cementitious material in concrete mixes. The overall procedure for making CSCP from coconut shells includes the pyrolysis of coconut shells into char, followed by steam activation in a fluidized bed reactor. The activated carbon that results is 97% pure. Concrete made with CSCP as a partial cement substitute at levels of 1%, 2%, 3%, and 4% by weight of cement has superior performance characteristics when compared to normal concrete, according to research. Furthermore, the use of CSCP would result in a reduction of the environmental greenhouse effects.

Water is essential in the production of concrete since it initiates the interaction between the cement, pozzolan, and aggregates. It aids in hydrating the mixture. The water utilised in this study was plain water.

1.4 Aggregates This research is limited to sand gathered from the river. The sand was collected to ensure that there was no allowance for potentially harmful materials in the sand. In this study, aggregates with a maximum size of 20mm have been used.

Concerns and the requirement to conserve energy and resources, efforts have been made to burn the coconut shells at a controlled temperature and atmosphere, and to utilize the ash so produced as a supplementary cementing material. Key Words: Carbon Powder, Activated Carbon, CSCP, Coconut Shells.

1. MATERIALS USED 1.1 Coconut Shell carbon Powder (CSCP) Activated carbon is a low-cost material with distinguishable properties like high specific surface area, high porosity, and desired surface functionalisation. Because of that, activated carbon is diversely used for effective applications in adsorption, removal of pollutants, water treatment, and energy, etc.

2. METHODOLOGY The fundamental goal of this work is to examine the potential of coconut shell carbon powder as a pozzolanic material for cement replacement in concrete. However, it is believed that the addition of coconut shell carbon powder in concrete will increase its strength qualities.

There are four types of carbon powder material. They are: a.

Coconut shell Carbon powder,

Fruit shell carbon powder,

Coal carbon powder,
