Turning Sand to Stone — 13 Comments

      • Please help me with a starting point for my research. I live near the shore and my property is mostly a fine white sand that they call ‘sugar sand’ locally. I would like to build a house/building on site with this material, however, I don’t want to use cement. I want it to be actual stone made from this sand. I can only find the basic information online that it can be done, however, I can’t find the actual recipe for making stone from sand.

        • beach rock
          is the marine version of this.
          into see water mix a bit of sugar and plant fertilizer, to feed the bacteria. use this to moisten your sand. the bacteria needed to make beach rock (sandstone) is already present in the water.

          you will have to do a bit of experimenting to work out how much fertilizer and or sugar is needed, I suspect it will be very little.

          if I was going to use this for load being or walls I would include a lot of hard rock to carry the weight.

  1. Combine this technology with the gantry of Dr. Koshnevis at USC and you have a way to build 2,000 sf. homes in just 24 hours

  2. The method of construction – to grow the building – described in the fantastic novel “One Hundred years ahead,” Kir Bulychev. I advise you to read)

  4. What about misting earthen walls (adobe, rammed earth, cob) or even earthen plaster with MICP and allowing it to gradually turn the surface to stone? Please let me know if you find out more about this.

  5. Another possibility is using MICP in PISE (pneumatically impacted stabilized earth). This would create rock hard plaster that looks like stone. No cement or lime plaster required. (Note: typical PISE has cement, but MICP would make it unnecessary.)

    Also note how MICP stabilized PISE wouldn’t require high pressure equipment, because it gains strength through a chemical reaction. Much lower cost and easier to use equipment like a Tirolessa mortar sprayer would would great.

  6. One possibility that springs to mind is using rapidly degradable natural material in place of polypropylene tubes or bags. Burlap is sprayed with nasty chemicals, but maybe you could special order burlap bags before treatment. It wouldn’t matter if the bags decomposed because you’d end up with a stone wall. You could cut away the exposed burlap to improve bonding with plaster. (For those who don’t know, using bags or tubes eliminates the need for expensive and time consuming metal or wood forms.)

    Footnote: Years ago I saw stone similar to this in the desert in New Mexico and often wondered how to create houses by replicating the natural process with something like shotcrete.
