(2) cement: the cement that the present invention adopts is the silicate cement of common label.
(3) auxiliary stopping composition: the auxiliary stopping composition that the present invention adopts includes: wherein one or more of common coal ash, sand, building stones.
B, feedstock production
(1) slag is pulverized
Slag through the first pulverizing of size reduction machinery, middle pulverizing after, carry out magnetic separation, isolate rich scum after, slag through superfine grinding, selection by winnowing, is separated into ultrafine powder and slag aggregate.The ultrafine powder particle diameter is 2 to 8 millimicrons, and slag particles of aggregates diameter is 0.1 to 20 millimeter.
(2) auxiliary stopping composition screening
Coal ash, sand, broken, the screening of building stones process, screening back particle diameter is less than 20 millimeters respectively, and it is standby to classify.
C, proportioning raw materials are pressed product weight percentage calculation (as follows)
Cement 2 to 15
Ultrafine powder 2 to 15
Slag aggregate 50 to 96
Auxiliary stopping composition 0 to 46
D, production technique
(1) mixes
By said ratio, cement, ultrafine powder, slag aggregate, auxiliary stopping composition are packed in the stirrer, adds an amount of clear water, evenly stirring becomes compound.
(2) compacting
Above-mentioned compound poured in the materials for wall mould vibrate, under the pressure of 5 to 25 MPas, normal temperature compression moulding.
(3) maintenance
Carry out maintenance by the curing procedure of Portland cement prefabricated component and become product of the present invention.
Owing to adopt patent of the present invention; give full play to the physicochemical characteristic of slag aggregate, ultrafine powder; make product ultimate compression strength, tensile strength, water permeability resistance, the every quality index of dry shrink value all meet or exceed national standard; not only reduce production costs; and solved the difficult problem that China's slag is handled, protect environment.
