Abstract
A carbon dioxide consuming material and a method for manufacturing it from waste released in the building industry, including: a primary crushing step 5 for crushing concrete fragments 1 under a pressure; a secondary crushing step 7 for crushing or smashing primary-crushed concrete fragments 11 from the primary crushing step by utilizing a grinding motion in a highly dense and pressurized condition; and a screening and separating step 8 for mixture of products obtained by the secondary crushing step.
Claims7
A method for manufacturing a carbon dioxide absorber from building industrial waste, comprising:
- a first crushing step for crushing concrete fragments under a pressure and for obtaining primary-crushed concrete fragments;
- a second crushing step for crushing said primary-crushed concrete fragments with a grinding motion in a highly dense and pressurized condition and for obtaining mixture of reproduced products;
- and
- screening and separating fine cement mortar component from said mixture of reproduced products.
