Problems solved by technology

The main components of ordinary air-entrained concrete particle mortar are air-entrained concrete particle and sand. Traditional air-entrained concrete particle mortar has shortcomings such as cracks, hollowing, and poor bonding performance as a plastering material. Secondly, the solidification and hardening speed is slow.

Description

Technical field [0001] The present invention relates to the technical field of building materials, specifically to a composite type of environmentally friendly cement mortar. Background [0002] A mixture of aerated concrete particles, sand and water is called aerated concrete particle mortar. It is used for construction projects and other places, such as building houses. The main component of ordinary aerated concrete particle mortar is aerated concrete particles and sand, and the adhesion of aerated concrete particles and sand together is also quite strong, but with the influence of dry and excessive humid environment, it will affect the adhesion of aerated concrete particle mortar. [0003] Aerated concrete particles as a kind of water-hard cementitious materials in the field of construction engineering are widely used, its main characteristics are the plasticity after adding an appropriate amount of water, not only can be hardened in the air, but also in the water hardening. ...
