Abstract

The invention discloses a plasticity stabilizer for mechanical spraying mortar. The plasticity stabilizer comprises the following ingredients in parts by mass: 20-22 parts of a retarder, 20-22 parts of a water reducer, 12-14 parts of cellulose ether, 0.5-1 part of a thixotropic agent, 25-30 parts of bentonite and 15-20 parts of attapulgite. The plasticity stabilizer is applicable to the mechanicalspraying mortar, and can improve thixotropy, water retention, pumpability and storability of the mortar.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a plastic stabilizer for mechanically sprayed mortar. Background technique [0002] Since the 1970s, my country began to study the mechanized construction of mortar, and carried out tests at many construction sites. However, at that time, the mechanized construction of mortar could not be realized due to factors such as inhomogeneous mixing of mortar particles and unstable quality. In recent years, with the development of ready-mixed mortar and the introduction of foreign mortar spraying machine construction equipment and other factors, the mechanized construction of ready-mixed mortar has begun to be applied to construction projects in Beijing, Shanghai, Guangzhou, Jiangsu and Zhejiang. Gained a lot of construction experience. [0003] During the spraying process of machine-sprayed mortar, the storage period of mortar is short and the stability is poor, the pumping p...
