目前机械化抹灰工艺广泛采用喷涂法,为了避免泵送灰浆在输送管内引起堵塞,重要的是使灰浆本身始终保持其良好的保水性能。本文利用造纸废液和纸浆废泥作为外加剂,来减小灰浆的泌水率和分层度,从而提高灰浆的可塑性。通过多次试验和初步施工应用,收到了良好的效 At present, the spraying method is widely used in the mechanized plastering process. To prevent the pumping mortar from causing blockage in the conveying pipe, it is important that the mortar itself always maintains its good water retention performance. In this paper, papermaking waste liquid and pulp waste sludge are used as admixtures to reduce the bleeding rate and delamination degree of the mortar, thereby improving the plasticity of the mortar. Passed many tests and preliminary construction applications, received good results
