<p>The invention concerns a method for manufacturing a cement and foam polymer mix, whereby the foam polymer comprises separate particles. Th foam polymer is treated so that the surface binds dry cement whereafter dry cement is mixed with the separate particles of foam polymer and the cement becomes bound at the surface of the foam polymer particles. The invention also concerns a cement and foam polymer mix, comprising separate particles of foam polymer The separate particles of he foam polymer, treated so that its surface melts, are mixed with cement, whereby the cement is bount at the surface of the separate particles of foam polymer.</p> |
