摘要：The experiment work carried out by micro silica as a supplementary material for cement and evaluatecement for M20 grade of concrete. We are adding 0%, 5%, 10%, 15%, and 20% by weight of cement in concrete. Thematerial chosen for structural up gradation should not pollute the environment. They should be accessible to theordinary people and low monetary cost. Coconut fibre is abundant, versatile, renewable, cheap and more resistantthermal conductivity. Coconut fibres have the highest toughness amongst natural fibre. They have potential to be usedas reinforcement in low cost concrete structures, especially in tropical earth quake region. The aim of investigation isstudy the possibilities to use coconut fibre in addition to other constituents of concrete and strength properties. Theinfluence of 1%, 2% and 3% fibre content by mass of cement and aspect ratio 125, fibre cut length 2.80cm isinvestigated. To evaluate the effect of coconut fibres improving the properties of concrete.At 1% addition of coconutfibre, 5% silica fume with water cement ratio 0.53.compressive strength test and split tensile strength gives best resultin concrete.
