Abstract

The invention discloses an energy-saving environment-friendly mortar admixture for increasing the application area and a preparation method thereof. The energy-saving environment-friendly mortar admixture for increasing application area comprises the following raw materials in parts by weight: 580-680 parts of ore powder, 250-350 parts of sepiolite, 8-12 parts of white carbon black and 60-100 parts of AES. The obtained energy-saving environment-friendly mortar admixture can replace the whole lime in mixed mortar and generate micro emulsified foaming in the mortar to improve the mortar yield ofthe mortar after stirring without reducing the mortar yield by replacing the lime, can efficiently diffuse the agglomerated cement masses for thorough hydration so as to significantly enhance the strength of the mortar, and can significantly improve the workability of the mortar so as to ensure the good fluidity and water retention of the mortar, make the mortar soft, plastic and elastic, reducethe labor intensity of workers, improve the efficiency and improve the progress of masonry.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an energy-saving and environment-friendly mortar admixture for increasing the application area and a preparation method thereof. Background technique [0002] The main performance indicators of mortar include strength and workability. Among them, the strength mainly refers to the compressive strength of the mortar after molding, which depends on the composition, degree of hydration and coagulation effect; the workability of the construction mainly refers to the ease of construction operations of the mortar, including mixing, transportation, pouring, tamping, etc. , and can obtain the performance of uniform quality and compact molding, which includes thixotropy, fluidity, cohesiveness and water retention. [0003] With the development of social economy, the cost of labor is getting higher and higher, and higher requirements are put forward for the quality and effect of...
