Slump-retaining modified naphthalene water reducer and preparation method thereof
The invention provides a slump-retaining modified naphthalene water reducer and a preparation method thereof. A molecular structure of the slump-retaining modified naphthalene water reducer contains phosphate groups which refer to substituted phosphoric acid, hydrogen phosphate and phosphate. The performance defect of rapid slump loss through time of the conventional naphthalene water reducer is overcome, when the slump-retaining modified naphthalene water reducer is applied to concrete, excellent slump retention is realized, the water reducing performance is high, and the early-age strength of the concrete is not affected.
