Abstract
A process is provided for the manufacturing of machine parts wherein a concrete polymer including a filler mixture formed of rock particles and a binding agent matrix is employed. It is provided that as the fine part of the filler mixture, particles are used that are made of mechanically resistant materials having a modulus of elasticity that is higher than the rock. It is also provided that essentially cubic broken rock particles are used and that the mixture of rock and fine particles and the binding agent system is condensed in a casting mold in such a way that as many of the adjacent particles as possible contact one another.
Claims20
A polymer concrete article comprising:
- substantially cubic rock particles having a grain size at least equal to a preselected value, said rock particles abutting in a substantially planar manner, said rock particles having a first modulus of elasticity, and
- mechanically resistant fine particles having a grain size less than said preselected value and having a second modulus of elasticity greater than said first modulus of elasticity, said fine particles being located essentially in hollow spaces between said cubic particles, and
- a binding agent.
A process for manufacturing a polymer concrete article comprising:
- forming a polymer concrete mixture by combining substantially cubic rock particles, at least one mechanically resistant fine material having a modulus of elasticity greater than the modulus of the elasticity of the rock particles, and a binding agent,
- placing said polymer concrete mixture in a casting mold, and
- condensing said mixture in said mold so as to cause said rock particles to contact one another and to cause the binding agent and fine material to be at least partially displaced into hollow spaces between the rock particles.
