Prestressed Concrete Sequence:
“The hydraulics possibilities include the local cements, water, air, gravel, sand, and rocks. The economic theory behind prestressed concrete is based on prefabrication and shipping only the small bulk of steel as a tensional sinew system, and applying the local water, sand, gravel, and cement as the building bulk. The particles which make up cement are sifted sand and gravel, which, though they look rough, pack averagedly as spheres would pack-- in 60-degree angular packing. Few people think of cement that way, but if it is shaken down, agitated well, and lubricated together with a colloid, it will automatically avail itself of nature’s tetrahedral structuring in closest packing pattern.”
