Abstract
The invention discloses an aerated concrete interface agent, and belongs to the technical field of construction materials. The agent comprises, by weight: 20-50% of cellulose ether, 36-73% of a thixotropic thickener, and 5-25% of redispersible latex powder. The agent has the advantages that: with the agent, bonding strength of mortar upon a substrate layer can be improved, construction workability can be improved, surface smoothness can be improved, adhesion with tools during construction can be reduced, water-retention and thickening performances are excellent, mortar operation open time can be prolonged, and problems such as building block falling, adhesion surface shrinkage cracking, and the like can be effectively avoided.
Description
technical field [0001] The invention relates to an air-entrained concrete interface agent, which belongs to the technical field of building materials. Background technique [0002] Due to the requirements of energy saving and environmental protection, the current building blocks are mainly aerated concrete blocks with high water absorption and low strength. At this time, if the traditional masonry mortar is used directly in the project, the blocks will fall off and the bonding surface will shrink. Problems such as cracking directly affect the construction quality of the project. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides an air-entrained concrete interface agent, which is used to solve problems such as block falling off and bonded surface shrinkage and cracking in engineering using traditional masonry mortar. [0004] In order to achieve the above object, the technical solution adopted in the ...
