Abstract

The invention relates to an antifreezing polycarboxylic acid composite pumping water reducing agent and application thereof. The antifreezing polycarboxylic acid composite pumping water reducing agent comprises the following components in percentage by weight: 8-12% of polycarboxylic acid high efficiency water reducing agent, 0.5-1% of plastifying component, 0.05-0.1% of air entraining agent, 0.8-1.5% of triethanolamine, 8-15% of inorganic early-strength component, 8-15% of organic antifreezing component and the balance of water. Various organic and inorganic components and the polycarboxylic acid water reducing agent mother solution in the antifreezing polycarboxylic acid composite pumping water reducing agent have favorable compounding effect, and thus, the product is uniform and stable, and does not have the phenomenon of stratification.

Description

technical field [0001] The invention relates to a composite pumping water reducer, in particular to an antifreeze type polycarboxylate composite pumping water reducer and its application. Background technique [0002] In recent years, the research and application of polycarboxylate-based high-performance water-reducers has developed rapidly in my country. Due to the excellent working performance and environmental protection characteristics of polycarboxylate-based water-reducers, from high-speed railways to urban commercial concrete mixing Station, many domestic application companies began to choose polycarboxylate superplasticizer as the fifth necessary component of concrete. However, due to the relatively short development time of polycarboxylic acid-based high-performance water-reducers in my country, its application technology research is still in its infancy, and the theory and experience of compounding naphthalene-based water-reducers with other admixtures are no longer...
