Step 4: Sand Out the Shell. To finish off the texture and prepare the bowl for lacquering/waterproofing, take a 6x7 rough-grain sheet of sandpaper and tear it into quarters, then fold one of these smaller sheets double. Sand down the inside of the bowl until it feels smooth and there are no loose bits of coconut "hair" when you run your fingers ...
Cement is used as the binding material for coconut shell and sand. In this study, a standard mix used is cement: sand, which is ratio 1: 6, a coconut shells are added by using difference ratio. The mix proportions of CSCSB are cement: sand: coconut shells, ratios used are 1: 5: 1, 1: 4.5: 1.5 and 1: 3: 3.
13-10-2018· The focus of this study is on the development of self-compacting lightweight concrete using local waste materials and investigation of its mechanical properties. Discarded fresh coconut shells were crushed mechanically and used as coarse aggregate with fly ash (FA) as partial replacement of Portland cement at 15% and 20% replacement levels by weight. Slump flow, T500, V-funnel, L …
Further, brick dust and coconut shell was partially replaced with cement and coarse aggregate respectively in different proportion and the compressive strength test on the concrete was performed.
Coconut shells which were already broken into two pieces were collected from local temple; air dried for five days approximately at the temperature of 25 to 30 o C; removed fibre and husk on dried shells; further broken the shells into small chips manually using hammer and …
