The maximum compressive strength was attained at an aspect ratio of 83.33 and volume fraction of 3% for conventional concrete, and aspect ratio 66.67 and volume fraction 3% for coconut shell concrete. Flexural strength increased by 30.63% (conventional concrete) and 53.66% (coconut shell concrete) on the addition of coconut fibers.
concrete production makes concrete as sustainable and environmentally friendly construction material. In this research, the effect of coconut shell as partial replacement of coarse aggregate and waste glass as partial replacement of fine aggregate on the properties of concrete were studied.
Coconut shell which is referred to as endocarp may be useful as aggregate for concrete production. However, the concrete produced using coconut shell as either main aggregate or
concrete and asphalt pavements The best aggregates to use for strength are crushed stone or crushed gravel. Crushed aggregate have irregular, angular particles that tend to interlock when compacted or consolidated. The crushed stone or crushed gravel aggregate make the asphalt or concrete mix somewhat difficult to place.
determine durability of the concrete. Thus, the aim of this work is to provide more data on the strengths of coconut shell concretes at different coconut shells (CS) replacements and study the transport properties of concrete with CS as coarse aggregate replacement.
Jun 01, 2017· Waste coconut shell has potential of being used as coarse aggregate in concrete . The present study focuses on use of waste coconut shell (CS) as partial replacement of conventional coarse aggregate (CA) for concrete production. 2. Application of coconut shell as coarse aggregate
Coconut fiber was used in coconut shell concrete (CSC) and its durability properties were studied. The properties include: water absorption, volume of permeable pore voids, rapid chloride penetration test, sorptivity and resistance at elevated temperature. For comparison purpose, these properties were also studied on conventional concrete (CC) with coconut fibers.

Coconut Shell as Partial Replacement for Coarse Aggregate: Review 213 While natural material is coconut shell as course aggregate will be investigate to replace the aggregate in concrete. Lightweight concrete is typically made by incorporating natural or synthetic lightweight aggregates or by entraining air into a concrete mixture.
demand of concrete and scarcity of raw material. Hence the concrete technologists must search for some economical alternative to the coarse aggregate. In this study, M20 grade of concrete was produced by replacing coarse aggregate by coconut shell aggregate of 12mm-10mm. Thirty six cubes were casted and their compressive
To enhance the coconut shell concrete property, cement is partially replaced with GGBS. • The micro-structural characterization has proved that incorporating GGBS has improved the hydration process. • The IMM study has clearly shown improvisation in the interfacial transition zone (ITZ) of coconut shell concrete.
The application of coconut shell concrete to flooring concrete and surface coatings. etc. D. This project suggests reduction in amount of coarse aggregate. E. On one hand the waste disposal problem is solved and on other hand the coconut shell is gainfully utilized. F.

The Compressive Strength of the concrete using Coconut Shell partially replaced with aggregate reduced as percentage of Coconut Shell increases. The result of the compressive strength of concrete cubes show that the compressive strength upto 40% replacement gives good result and highly reduced as percentage of Coconut Shell increase after 40%.
Concrete made from cement blended with pozzolans are more durable even in harsher service environments as in phosphate and sulphate environments . The data presented herein can be a tool to assess the pozzolanic activity of coconut shell as a possible partial cement replacement. 2. Experimental design, materials, and methods

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. For the selected mix, two different water–cement ratios have been considered to study the effect on the ...
coconut shell concrete has better 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. Moisture retaining and water absorbing capacity of coconut shell are more compared to conventional aggregate. The amount of
The properties of coconut shell and coconut shell aggregate concrete is examined and the use of coconut shell aggregate in construction is tested. The project paper aims at analyzing flexural and compressive strength characteristics of with partial replacement using M30 and M20 grades of concrete.
This makes it a material of choice in construction. This research work reports the investigation carried out to determine the use of coconut shell as an aggregate in light weight concrete. Concrete samples were produced with different mix ratios, to determine the best and economic proportions that will give acceptable compressive strengths.

188.8.131.52 Coconut shell aggregate abrasion value The coconut shell abrasion value ranges between 2.19 to 2.26 percent as shown in Table 3.25 of chapter 3. While the average abrasion value is 2.23% this is far less than 30%. Hence the coconut shell aggregate is a suitable material for construction as it satisfied the abrasion provision in the code. The implication of this result is that coconut ...
