Fine-grounded burned ceramic (1) as puzzuolanic additive (2) in production of cement, or concrete, according to figure 1, is produced by burning clay chips (15) in rotating furnace (9, 10 and 11), so we got burned ceramic (1). Said ceramic is milled into fractions less than 0,09 mm in mills with bawls (12), so we got ceramic puzzuolanic additive (2) with condition that puzzuolanic activity should be 5 MPa (+/-1,5 MPa). The produced burned ceramic can be measured by two methods. The first method, according to figure 2, of measuring is that in the mixers (13) ceramic puzzuolanic additive (2) is homogenized in quantity of 10-15 % (as one of the main conditions) with pure Portland cement (14). The produced cement (3) is packed in to the bags or it is batched bulk. The second method, according to figure 3, of measuring is consisting of the following steps. The ceramic puzzuolanic additive (2) is measured into concrete mixer in quantity of 10-15 % (as one of the main conditions) of the whole mass of cement (3). Using said cement, consisting of 10-15 % of ceramic puzzuolanic additive (2) with small puzzuolanic activity of 5 MPa (+/-1,5 MPa) (as one of the conditions) and of 85-90 % of pure Portland cement (14), we can produce highly resistant and durable concrete.
