Actually i am intersted in a stone that can make using the laminated ferrocement method. The reason for following this method is that I need to make the stone materials i work with lighter so that i can handle it because i don't have a team or slaves. My building team consists of one woman only. In the laminated ferrocment method, for your information, it goes like this. lay 1/8 inch mortar made with 50% each sand and portland cement (do you have a better idea of what to use and a better mortar recipe?) lay in a sheet of expanded lath metal. This is galvanised and light. And i also might try some experiments with split bamboo. lay and other 1/8 inch mortar lay another sheet lath until you have three sheets of lath in the mortar mix. The top layer is mortar. I have planned on making a type of plank because I think i can handle the weight and size. I Mean the plank is going to be my basic building block. It needs to be strong enough to walk on. I mainly need it for floors and all structural members that are normally called beams, bearers and joists. I may do some walls. I also want to use this method for making built in furniture in all my rooms. do you have a stone recipe or mortar recipe using materials other than portland cement that i could use? What will be the advantages? Will it be as easy as using portland cement? Will the cost be comparable? What about finding teh materials? All i know at the moment is that we have stone quarries around here and there is lime but it is not hydraulic or hydrated lime. It is lime meant to be used straight on the garden. I don't know if there is any other type of treatment plant around but i could look into it if you think its worthwhile. I think it is unlikey that i will be doing any lime cooking.
