Embodiment 1

[0033] Example one (inner wall plastering dry-mixed mortar):

[0034] formula:

[0035] Slag powder: 25Kg Fly ash: 7Kg

[0036] Machine-made sand: 68Kg (fineness less than 4mm) Compound activator: 0.4Kg

[0037] Hydroxypropyl methylcellulose: 0.015Kg Wood fiber: 0.4Kg

[0038] The composite activator is a mixture of sodium silicate and sodium thiosulfate with a weight ratio of 1:1.

[0039] Preparation:

[0040] After the various raw materials are accurately measured according to the above formula, the target product is obtained by mixing and forced mechanical stirring evenly.

Embodiment 2

[0041] Example two (external wall plastering dry-mixed mortar):

[0042] formula:

[0043] Slag powder: 25Kg Fly ash: 7Kg

[0044] Machine-made sand: 68Kg (fineness less than 4mm) Compound activator: 0.4Kg

[0045] Hydroxypropyl methylcellulose: 0.015Kg Wood fiber: 0.4Kg

[0046] Sodium stearate: 0.6Kg

[0047] The composite activator is a mixture of sodium silicate and sodium thiosulfate in a weight ratio of 1:1.

[0048] Preparation:

[0049] After the various raw materials are accurately measured according to the above formula, the target product is obtained by mixing and forced mechanical stirring evenly.

[0050] During the construction process, the water consumption is calculated according to the standard water consumption with a slurry diffusion diameter of 150±5 mm. Before construction, the wall surface should be fully moistened, and the materials should be fully mixed evenly to produce better strength.

[0051] According to the standard method used in my country's construction indu...

[0053] Example three (inner wall plastering dry-mixed mortar):

[0054] formula:

[0055] Slag powder: 22Kg Fly ash: 9Kg

[0056] River sand: 73Kg (fineness less than 4mm) composite activator: 0.35Kg

[0057] Phosphated starch: 0.012Kg polyacrylonitrile fiber: 0.45Kg

[0058] The composite activator is a mixture of sodium silicate and calcium oxide with a weight ratio of 1:1.

[0059] Preparation:

[0060] After the various raw materials are accurately measured according to the above formula, the target product is obtained by mixing and forced mechanical stirring evenly.

Abstract

The invention discloses slag micro-powder dry mixed mortar, and belongs to the field of premixed dry mixed mortar materials. The dry mixed mortar is prepared from the following materials in part by weight: 20 to 30 parts of slag micro-powder, 5 to 10 parts of fly ash, 60 to 75 parts of aggregate, 0.3 to 0.5 part of composite exciting agent, 0.01 to 0.03 part of water holding agent, and 0.3 to 0.5part of anti-cracking agent. Compared with the prior art, because the slag micro-powder is directly prepared into the dry powder mortar, the slag micro-powder dry mixed mortar has the characteristicsof energy conservation, environmental friendliness, low material cost and the like.

Description

Technical field [0001] The invention relates to a ready-mixed dry-mixed mortar material for construction, specifically a dry-mixed slag powder powder. Background technique [0002] With the development of society, people's requirements for project quality, environmental protection requirements and civilized construction continue to increase, and the advantages of dry-mix mortar are favored by more and more people. [0003] In the prior art, the main cementing material of the mortar is cement or gypsum, and the amount of cement is not less than about 15%, and the amount of gypsum is not less than 30%. Although fine slag powder can also be used in a small amount, it can only be used in cement together with cement clinker and fly ash. Summary of the invention [0004] The technical task of the present invention is to provide an energy-saving, environmentally-friendly, and low-cost dry-mixed slag powder dry-mixed mortar for the above-mentioned shortcomings of the prior art. [0005] The...
