heat your shells or other cement items (see step 1) for 4-7 hours, or until they start to become brittle and start to crumble in to sand like dust. to help make your shells or other cement into a more consistent sand, stir it every 30 minutes by mixing the shells (just like cooking).morethere will
the results of mix design indicate that crushed sand can also make as good a concrete as that made of natural sand.the compressive strength obtained is same as of normal mixes.in fact use of crushed sand will become inevitable in near future because of dwindling sources of natural sand.morethere will
