Problems solved by technology

Due to the influence of the technical proficiency of the construction personnel and the quality of various raw materials such as cement and sand, the mortar used on the construction site, whether it is masonry mortar, plastering mortar, or ground leveling mortar, often has cracking phenomena in building plastering mortar ( Even if the most traditional clay brick walls are plastered with cement mortar, there will be large-scale cracks), resulting in unstable project quality, insufficient strength, and even poor quality, which has become a common problem in construction quality

Embodiment 1

[0012] Embodiment 1: a kind of ready-mixed mortar of the present invention, by weight, comprises following components: 50 parts of iron slag, 30 parts of fly ash, 20 parts of cement, 40 parts of sand material, 5 parts of wood fiber, latex powder 3 parts, 2 parts of calcium nitrite, and 15 parts of sepiolite, wherein the cement is preferably 32.5 grade ordinary Portland cement, and the sand material is preferably quartz sand with a particle size of 50 mesh, and its water content is less than 3%.

Embodiment 2

[0013] Embodiment 2: a kind of ready-mixed mortar of the present invention comprises following components by weight: 60 parts of iron slag, 40 parts of fly ash, 30 parts of cement, 50 parts of sand material, 8 parts of wood fiber, latex powder 5 parts, 4 parts of calcium nitrite, 20 parts of sepiolite, wherein the cement is preferably 32.5 grade ordinary Portland cement, and the sand material is preferably 60-mesh quartz sand with a water content of less than 3%.

Embodiment 3

[0014] Embodiment 3: a kind of ready-mixed mortar of the present invention, by weight, comprises following components: 80 parts of iron slag, 50 parts of fly ash, 40 parts of cement, 60 parts of sand material, 10 parts of wood fiber, latex powder 6 parts, 5 parts of calcium nitrite, and 25 parts of sepiolite, wherein the cement is preferably 32.5 grade ordinary Portland cement, and the sand material is preferably quartz sand with a particle size of 70 mesh, and its water content is less than 3%.

[0015] The ready-mixed mortar of the present invention has high tensile strength, strong cohesive force, and is not easy to shrink and crack; the cost is low, and a large amount of industrial waste is used, which not only reduces the product cost but also can turn waste into treasure, which is beneficial to energy saving Environmental friendly.

Abstract

The invention discloses premixed mortar. The premixed mortar contains the following components in parts by weight: 50-80 parts of iron-ore slag, 30-50 parts of coal ash, 20-40 parts of cement, 40-60 parts of sand, 5-10 parts of wood fibers, 3-6 parts of latex powder, 2-5 parts of calcium nitrite and 15-25 parts of sepiolite. The premixed mortar is high in tensile strength and strong in adhesion force and unlikely to be drily shrunk and cracked; the cost is low, and a large quantity of industrial wastes are adopted, so that the product cost is lowered, waste can be turned into wealth, and the energy conservation and the environment protection are promoted.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a ready-mixed mortar. Background technique [0002] With the improvement of people's living standards, the requirements for building quality are getting higher and higher. Due to the influence of the technical proficiency of the construction personnel and the quality of various raw materials such as cement and sand, the mortar used on the construction site, whether it is masonry mortar, plastering mortar, or ground leveling mortar, often has cracking phenomena in building plastering mortar ( Even if the most traditional clay brick wall is plastered with cement mortar, there will be large-scale cracking), resulting in unstable project quality, insufficient strength, and even poor quality, which has become a common problem in construction quality. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a ready-mixed mort...
