STONE BLOCKS FROM THE BOSNIAN PYRAMIDS ANALIZED; RESULT – ANCIENT CONCRETE!

The Institute for materials from the University in Zenica, Bosnia-Herzegovina, published the first results of archaeological samples taken from a number of locations in the Bosnian Valley of Pyramids, reported the “The Archaeological Park: Bosnian Pyramid of the Sun Foundation” that gathered samples and sent them for analysis.

“The builders of the Bosnian pyramids manufactured building materials and built them into the construction of various architectural forms. For this material they used various sized grains of gravel that was available in quantities at the time. They knew the binding properties of natural materials, especially clay, its elasticity, hygroscopicity, and that poorly baked clay crushed with water possesses binding properties”, concluded professor Muhamed Pasic from the Institute for materials.

They also used a lime hydrate in order to bind the grains of gravel. They knew about the production of calcite and dolomite lime. The building material of ancient cultures was a gravel-like mix that was made at the site from gravel, binding materials and water, and then the made material would be poured into the slabs at the Bosnian Pyramid of the Sun.

The gravel-like material that they made the pyramid from is reminiscent of today’s cement concrete from a gravel machine, but highly surpasses its hardness with over 100 Mpa.

Volume mass (Vm) and Density (ρ) of this hard and compact artificial material shows the following results:  Vm = 2,68 kg/dm3     ρ = 2,71 g/cm3 Since there is practically no difference between the volume and density (0,03) it further confirms the artificiality of the concrete blocks with almost no porozity.

This hard material with the hardness of over 100 Mpa have better properties than any other industrial concrete which is made today in Bosnia. Such concrete is made only at special request.

From these adhesive materials (poorly baked clay and dolomit/calcit carbonate) tools were made in special molds and later used to cut and shape sandstone plates found on Bosnian Pyramids of the Sun and Moon.

The samples will also be sent for analysis to some of the leading institutes in Europe and America.You can read more about it at: www.piramidasunca.ba/en  or www.icbp.ba
