Problems solved by technology

[0002] The impermeability of exterior walls is one of the important issues that need to be solved urgently in today's building construction. The solid clay bricks used in large quantities in the past have been proved to be unsuitable for exterior wall construction; at present, the exterior wall materials used in construction are mainly vitrified hollow bricks. Microbeads are used as lightweight aggregate, river sand is used as auxiliary aggregate, lime calcium, cement and plasticizer are used as cementitious materials, mixed with an appropriate amount of anti-crack fiber material, mixed in an appropriate proportion and then stirred to form a single group Inorganic dry powder material insulation mortar, but generally has the disadvantages of large porosity, strong water absorption, and poor impermeability
[0003] Patent No. 201510480931.0 discloses a bonding mortar for ALC wallboard composed of Portland cement, fly ash, quartz sand, redispersible latex powder, lignocellulose, and polyacrylamide, which can be used for ALC Wallboard, but its impermeability is not ideal
[0004] Patent No. 201811038317.9 discloses a raw material including Portland cement, water reducer, defoamer, fly ash, lime calcium, quartz sand, composite high alumina cement, hydrophobic modified cellulose ether, hydrophobicity, but its strength and paste stability is not ideal
[0005] Moreover, since the mortar and water will cause the system to contain a large amount of water during construction, the surface strength and the actual strength after drying will increase slowly, affecting the construction effect and delaying the construction period
