Wet-mixed mortar adjusting plasticizer

Abstract

The invention discloses a wet-mixed mortar adjusting plasticizer which comprises the following components in percentage by weight: 9.20%-27.60% of a retarding component, 5.00%-15.00% of an air entraining component, 0.10%-0.30% of a water retention component, 0.10%-0.30% of a tackifying component, 0.10%-0.30% of an anti-corrosion component and 56.30%-85.00% of water. After the adjusting plasticizeris doped into wet-mixed mortar, a mortar system with higher compactness, stronger bonding force and higher water retention rate can be obtained, and the hydration speed can be reasonably adjusted, sothat the wet-mixed mortar meets the construction requirements within a specified time range.

Description

technical field [0001] The invention relates to the field of concrete admixtures, in particular to an adjusting plasticizer for wet-mixed mortar. Background technique [0002] In Southwest China, masonry, plastering and floor mortar are mainly mixed on site. The construction site mortar is mainly based on the variety and use, artificially adding lime king, mortar king, etc. according to the ratio to make plastering mortar, masonry mortar, and floor mortar. Mortar King and Lime King are mainly made by mixing auxiliary inert powders such as K12 and rosin. By 2009, dry-mixed mortar was mainly used in first-tier cities in Sichuan. [0003] Traditional Mortar King and Lime King are powder products. When used on site, due to ground materials, usage habits, climate, site and other reasons (more workers, less addition, missing addition, etc.), there are large quality fluctuations, abnormal mortar quality, construction There are many disputes and other issues, and most of the cons...

Problems solved by technology

[0004] By 2013, according to environmental protection requirements, technological innovation, and on-site management, the Sichuan region allowed the coexistence of dry mixing and wet mixing. The dry-mixing mortar company mixed sand, cement, admixtures, and admixtures in a certain proportion. Together, form different products, but there is a waste of resources

[0005] For dry-mixed mortar, the raw material sand needs to be dried and screened in advance, which wastes resources and is easy to separate during transportation. Statistics must be done on site, otherwise the remaining mixed mortar cannot be reused

At the same time, secondary mixing is required on site, and corresponding mixing equipment and manpower need to be invested. Dust pollution is generated during the mixing process. When mixing on site, the amount of water added is relatively random, which is not conducive to the quality control of mortar;

[0006] For wet-mixed mortar, there are problems such as low water retention, poor control of hydration rate, insufficient density of the mortar system, and insufficient adhesion.
