Wet-mixed mortar setting time regulator as well as preparation method and application thereof

Abstract

The invention provides a wet-mixed mortar setting time regulator as well as a preparation method and application thereof, belongs to the technical field of mortar additives and solves the technical problem of short opening time of the wet-mixed mortar. The wet-mixed mortar setting time regulator is prepared from the following components in parts by weight: 10-13 parts of saccharose, 10-13 parts of polycarboxylic acid water reducers, 10-15 parts of retarders, 0.02-0.04 part of air entraining agents and 60-80 parts of water. The preparation method of the regulator is characterized by mixing the saccharose, the polycarboxylic acid water reducers, the retarders, the air entraining agents and water according to parts by weight and uniformly stirring to obtain the regulator. An application method of the regulator in preparation of the wet-mixed mortar is characterized by adding the regulator with a cementing material counting for 0.8-1.2% of the total mass of the regulator into the wet-mixed mortar and uniformly stirring. Through the regulator, the opening time of the mortar is obviously prolonged under the precondition that the mixability of the mortar is ensured; the on-site operation and large-scale production by production manufacturers are facilitated.

Description

technical field [0001] The invention relates to a wet-mix mortar regulator, in particular to a wet-mix mortar setting time regulator and a preparation method and application thereof, belonging to the technical field of mortar additives. Background technique [0002] Mortar additive, mainly used in masonry and plastering mortar. After adding mortar additives, the mortar entry time can be arranged according to the workers' operating habits and working hours. In a short period of time, there is no need to worry about the mortar solidification, and there is no need to consider the waste of the remaining mortar. [0003] At present, the mortar additives mainly include lime king, modele, rock sand essence, mortar king, mortar treasure, etc. Most of them are workability regulators, and most of them are powder. The time is short, and the composition of cement components varies widely, and there are also adaptability factors between additives. In the process of use, traditional mort...

Problems solved by technology

[0003] At present, the mortar additives mainly include lime king, modele, rock sand essence, mortar king, mortar treasure, etc. Most of them are workability regulators, and most of them are powder. The time is short, and the composition of cement components varies widely, and there are also adaptability factors between additives. In the process of use, traditional mortar additives are used only, and the workability of the mortar in the early stage and the opening time in the later stage cannot be comprehensively controlled.
