| titleOfInvention | High strength cement composition comprising pozzolan as main material and manufacture device therefor |
| abstract | The present invention is a composition of a high-strength cement admixture applied to normal pressure steam curing or general ready-mixed concrete, and a manufacturing apparatus thereof, which is mainly based on industrial waste-based pozzolan materials such as fly ash and slag fine powder. By containing a certain amount of swelling agent and fluidizing agent, it is possible to prematurely activate pozzolanic, and to improve the strength, durability and fluidity, and to reduce the shrinkage after drying, it is mainly based on pozzolanic material for producing high quality secondary cement products. One cement admixture composition and its manufacturing apparatus, for which the composition of the present invention is 83 to 96% by weight fly ash to maintain a powder degree of 4000 ~ 6000 cm 2 / g; 3 to 6% by weight of fine slag powder to maintain a powder degree of 4000 to 6000 cm 2 / g; 0.1-5% by weight of anhydrous gypsum having a powder degree of 4000-5000 cm 2 / g; 0.5-6% by weight of expanding agent; And 0.5 to 2% by weight of a fluidizing agent;n n n The manufacturing apparatus includes a first storage unit capable of adjusting any discharge amount while the collected fly ash is input and stored; A classifier for accommodating the discharged fly ash and purifying it with a high powder of 4000 cm 2 / g or more; A centrifuge to which the purified fly ash is transferred and introduced; A second storage unit configured to discharge a small amount of auxiliary materials such as fine slag powder, anhydrous gypsum, an expanding agent, and a fluidizing agent, respectively and stored separately; A first meter for calculating an input amount of the discharged subsidiary material; A first mixer for even mixing of the weighed minor ingredients; A first bucket elevator for conveying the mixed material; A third storage unit for storing the mixed material transferred through the bucket elevator; A second meter for estimating the input amount of the fly ash passed through the centrifuge; A second mixer in which the mixed ash that has passed through the weighing and the third storage portion have been mixed in a predetermined ratio; A second bucket elevator for conveying the formulation; A third mixer for remixing the blend; A fourth reservoir for storing the ash mixture; And a discharge chute provided so that the completed storage is discharged and shipped through the fourth storage unit. |
