RELATIONSHIP AMONG THE AGGLOMERATION, MICROSTRUCTURE OF CLINKER AND THE PERFORMANCE OF HIGH BELITE CEMENT

摘要

The relationship among the agglomeration, microstructure of clinker and the performance of high Belite cement (HBC) had been discussed in this paper. The results showed that, for similar dense particles larger than 3mm, the smaller the size of it, the faster the cooling of the clinker and the more the α′-C_2S formed in it. The microstructure of the clinker and the performance of HBC will also be I better. The strength performance of HBC will be the best when the sizes of clinker particles lie in 5～15mm and Belite crystals formed are characterized by the intersecting lamella structure in which there are many foreign ions. The C_3S content in loose clinker will be relatively lower than the dense one of similar sizes and there will be no α′-C_2S in it. The strength performance of the cement made of it will be also lower than that of the cement made of dense clinker.
