TL;DR: In this article, a pre-stirring pre-mixing mortar with high moisture retention and a production method is presented. But the pre-Stirring mortar can effectively improve and ensure the qualities of the mortar buildings, obviously improves the construction environment, greatly decreases the production cost of the pre stirring mixture, and solves the difficult problems that the prior pre-STIRring mortar has over-high cost and are difficult to popularize and apply.
Abstract: The invention discloses pre-stirring mortar with high moisture retention and a production method thereof. The premixing mortar comprises the following components by weight ratio: 100 parts of cement with the high moisture retention, 1 to 900 parts of fine aggregate and 30 to 200 parts of water, wherein the cement with the high moisture retention contains a cellulose ether component and has the moisture retention above 90 percent; and the fine aggregate is natural sand or artificial sand obtain through screen sizing or removing harmful components, and has the maximum grain diameter of 1.18 mm to 2.36 mm. The production method comprises the following steps: arranging a mortar stirring machine on a construction site or nearby; adopting the cement with the high moisture retention and the fine aggregate to automatically meter and stir, enable mortar to be usable while stirring, and the like to ensure the mortar quality; and adopting a closed stirring mode, a dust-collecting mode and the like to reduce dust raise. The pre-stirring mortar can effectively improve and ensure the qualities of the mortar buildings, obviously improves the construction environment, greatly decreases the production cost of the pre-stirring mortar and solves the difficult problems that the prior pre-stirring mortar has over-high cost and are difficult to popularize and apply.
