Method for manufacturing concrete blocks and constructing fence

摘要

An improved method for manufacturing concrete blocks and constructing fencing. The method produces a concrete structure which includes two distinct types of complementary irregularly shaped glass particles. The first type of particle has interstices which are filled with vesicles or cavities of varying shape and dimension and which are pierced with a system of canals and capillaries. The canals and capillaries open on the surface of the particle. The second type of particle has spheroid shaped cells or bubbles sealed inside the particle and has small craters or hollows formed on the surface of the particles.
