Performance of coconut shell as coarse aggregate in concrete Results revealed that with 40% replacement of conventional coarse aggregate by coconut shell, 7 days compressive strength of concrete decreased by 62.6%; whereas decrease in 28 days compressive strength was only 21.5%. 40% replacement makes the concrete lighter by 7.47%.
PDF Coconut Shell as a Substitute for Coarse Aggregate in Coarse aggregate was replaced by crushed coconut shells in three different percentages namely 25%, 50% and 100%. Workability, compressive strength, flexural strength and splitting tensile strength
Coconut Shell as Partial Replacement for Coarse Aggregate: Reviewgranite aggregate. Coconut shell can be grouped under lightweight aggregate. There is no need to treat the coconut shell before use as an aggregate except for water absorption. Coconut shell is compatible with the cement. The 28-day air-dry densities of coconut shell aggregate concrete are less than 2000 kg/m3 and these are within the
Performance of Waste Coconut Shell as Partial Replacement of replaced the coarse aggregate by coconut shell and grained palm kernel in their study. Percentage of. replacement by coconut shell were 0%, 25%, 50%, 75% and 100% respective-ly. Conclusion is that the combinationof these materials has . potential of being used as. lightweight aggregate in co. ncrete and also has reduce the . material cost in
Strength Properties of Concrete Containing Coconut Shell as 2.70. This indi es that coconut shell is lighter than coarse aggregate and more volume of coconut shell will be required to replace equal weight of coarse aggregate in concrete. The bulk density of coconut shell obtained is 648 which far less thanis about 1437 of coarse aggregate implying its good for lightweight concrete.
PDF Properties of Concrete with Coconut Shells as Aggregate Therefore the coconut shell as partial replacement for coarse aggregate in concrete is studied. The density, slump and compressive strength of concrete are tested. The replacement of coarse
A Review of Partial Replacement of Fine Aggregate and Coarse Coconut Shell aggregates had given strength of 51 MPa at 28 days. 13 Damre Shraddha and Shrikant Varpe 2014 replaced conventional coarse aggregate with coconut shell and concluded that- with 50% replacement of coarse aggregates by coconut shells, the strength attained reduces invariably from 10%-20% as compared to the conventional
Performance of coconut shell as coarse aggregate in concrete 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.
