A study on naphthalene superplasticizer modified by polycarboxylate |
| |
Abstract: | A naphthalene superplasticizer modified by polycarboxylate copolymer was synthesized,which has more than 60% water and delaying 50 minutes retarding properties than that of naphthalene sulfonate superplasticizer and has hardly any slump loss within two hours for concrete performances. |
