concrete using coconut shells

2. Coconut shell as coarse aggregate The concrete obtained using Coconut Shell aggregates satisfies the minimum necessities of concrete. Coconut Shell concrete has superior workability because of the smooth surface on one side of the shells. The impact resistance of Coconut Shell concrete is high when compared with conventional concrete.

    The coconut shells were crushed using concrete hammersto a size such that it passes through a 20mm sieve and retainedon 4.75 sieve. Crushed shells were washed to remove fibres,mud, etc. from them. The washed shells were dried in sunlightfor 2 days. The crushed edges were rough and spiky as

  • Experimental Investigation of Concrete using Coconut Shell

    Apr 27, 2017 Coconut shell concrete is produced by adding coconut shells in different percentage (i.e. 0% to 30%) replacement in concrete. Test on ingredients Materials the ingredients of concrete i.e. cement, fine aggregate, and fine aggregate, coconut shells are tested before producing concrete.

  • Performance of coconut shell as coarse aggregate in concrete

    Jun 01, 2017 Using same mix design, coconut shell concrete was prepared by replacement of conventional crushed coarse aggregate (CA) with waste coconut shell (CS). Coconut shell replaced conventional aggregate by 10%, 20%, 30% and 40% respectively (by volume) and the effect on compressive strength and density of concrete was observed.

  • Mechanical and bond properties of coconut shell concrete

    Jan 01, 2011 The properties of concrete using coconut shell as coarse aggregate were investigated in an experimental study. Compressive, flexural, splitting tensile strengths, impact resistance and bond strength were measured and compared with the theoretical values as recommended by the standards.

  • Utilization of Coconut Shell in Different Forms in Concrete

    the concrete using coconut shell aggregate were 1975 kg/m3 and 19.1 N/mm2 respectively. ` At the different proportions, the compressive strength of concrete cubes produced with gravel and coconut shells, for seven (7) days curing, the average compressive strength for concrete cubes produced with coconut shell of

  • Assessing the Effectiveness of Coconut Shell CS as

    The coconut shell concrete was designed for characteristic strength of 30MPa with the incorporation of coconut shell as replacement for fine and coarse aggregate at 10%, 20% and 30% of volume fractions respectively. The workability, compressive strength as well as densities and water absorption of 96 cured

  • Journals About Coconut Shell Using In Concrete Beam

    1/09/2013 Abstract. Lightweight concrete has been produced using crushed coconut shell as coarse aggregate. The shear behavior of reinforced concrete beam made with coconut shell is analyzed and compared with the normal control concrete. Eight beams, four with coconut shell concrete and four with normal control concrete were fabried and tested.

  • An Experimental Investigation on Light Weight Concrete

    Apr 06, 2021 Abstract In this project, an experimental investigation of M25 grade of concrete with water cement ratio 0.42, by using coconut shell aggregate added in percentage of 0, 5, 10, 15 and 20 to test the effectiveness of coconut shell within the concrete, and also added steel fibers constant proportion of 0.5% by volume of the concrete.

  • Mechanical and Bond Properties of Lightweight Concrete

    Based on the relative analysis of concrete properties using coconut shell and palm kernel shell as coarse aggregates, Olanipekun et al. 5 reported that there is a cost decline of approximately 30% and 42% for concrete incorporating coconut shells and palm kernel shells, correspondingly.

  • Study of Strength of Concrete by Using Coconut Shell

    Coconut shell is used as light weight aggregate in concrete. Coconut shells are by-products of coconut oil production. Coconut shells are used in the production of activated carbon due to hardness and high carbon content. Various researchers have investigated the use of coconut shells and their derivatives in civil engineering construction. Cost
