摘要
Abstract
Mold gypsum is a kind of gypsum-based material which needs both considerable strength and larger water absorption. Polycarboxylate superplasticizer can increase the strength of the mold gypsum by changing its performance. At the same time, introduction of polypropylene fiber can improve the water absorption of mold gypsum. According to SEM, we can find polycarboxylate superplasticizer makes gypsum crystals develop completely and lap tightly. The mold gypsum's 2 h wet bending strength is 3. 6 MPa, dry bending strength is 6. 5 MPa, water absorption is 33.0%. It meet the requirements of first-class mold gypsum.关键词
