    New blocks, he suggests, could be cast in place, on top of and pressed against the old blocks. Proof-of-concept tests using similar compounds were carried out at a geopolymer institute in northern France and it was found that a crew of five to ten, working with simple hand tools, could agglomerate a structure of five, 1.3 to 4.5 ton blocks in a ...

  4. Bath stone - Wikipedia

    en.wikipedia.org/wiki/Bath_stone

    Great Pulteney Street, Bath, looking West towards Pulteney Bridge.The style and the Bath stone used are typical of much of the city. Bath stone is an oolitic limestone comprising granular fragments of calcium carbonate originally obtained from the Middle Jurassic aged Great Oolite Group of the Combe Down and Bathampton Down Mines under Combe Down, Somerset, England.

  5. Calcarenite - Wikipedia

    en.wikipedia.org/wiki/Calcarenite

    Calcarenite is a type of limestone that is composed predominantly, more than 50 percent, of detrital (transported) sand-size (0.0625 to 2 mm in diameter), carbonate grains. The grains consist of sand-size grains of either corals , shells , ooids , intraclasts , pellets , fragments of older limestones and dolomites , other carbonate grains, or ...

  6. Grain size - Wikipedia

    en.wikipedia.org/wiki/Grain_size

    Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials . This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.

  7. Mineral resource estimation - Wikipedia

    en.wikipedia.org/wiki/Mineral_resource_estimation

    The block model is essentially a set of specifically sized "blocks" in the shape of the mineralized orebody. Although the blocks all have the same size, the characteristics of each block differ. The grade, density, rock type and confidence are all unique to each block within the entire block model. An example of a block model is shown on the right.

  8. Calcilutite - Wikipedia

    en.wikipedia.org/wiki/Calcilutite

    Calcilutite (also known as cementstone) [1] is a type of limestone that is composed of predominantly, more than 50 percent, of either clay-size or both silt-size and clay-size detrital (transported) carbonate grains. These grains consist either of fossil fragments, ooids, intraclasts, pellets, other grains, or some combination of them.

  9. Massive precut stone - Wikipedia

    en.wikipedia.org/wiki/Massive_precut_stone

    A key technique of massive-precut stone ("MP stone") is to specify precut stone to precise dimensions that match the architect's plan for rapid construction, typically using a crane. [1] The blocks may be numbered so that the masons can follow the plan procedurally. The use of massive stone blocks has several benefits, listed below.
