Amino concrete pumping aid and preparation method thereof
The invention discloses an amino concrete pumping aid and a preparation method thereof, wherein the amino concrete pumping aid is composed of following raw materials, by weight, 30-60% of a naphthalene water reducer, 5-15% of an aliphatic-series water reducer, 5-20% of an amino water reducer, 0-6% of a retarder, 0.1-0.7% of an air entraining agent and the balanced being water. The preparation method includes following steps: weighting the raw materials according to the weight percentage ratio, pumping the naphthalene water reducer, the aliphatic-series water reducer and the amino water reducer into a stirring pot, stirring the materials for 25-30 min, adding the retarder with stirring for 5-10 min, adding the air entraining agent and the water with stirring for 1 h, and finally pumping out the pumping aid. The amino concrete pumping aid, which is formed by compounding multiple water reducers with single retardant, is high in strength, is good in pumpability, is good in flowability and is low in cost.
