Problems solved by technology

[0003] Conventional admixtures are often used in existing masonry mortars, which are derived from by-products (mineral powder and fly ash, etc.) produced by electric fields and steel mills. The product quality of the by-product fly ash and slag has also fluctuated greatly, resulting in the product quality of fly ash and slag (fineness of fly ash and slag, content of powder vitreous body, content of fly ash carbon content, specific surface area) is unstab

Example Embodiment

[0055] The present invention also provides a method of preparing a masonry, including steps:

[0056] With a weight part, 25-35 parts of cement, 10-20 parts modified ceramic polishing powder, 28-38 parts of sand, 1-2 parts of polycarboxylic acid water reducer, 1-2 parts of the thickener and water mixed , Stir dissolve, the resulting product is masonry;

[0057] The activity of modified ceramic polishing powder is> 65%.

[0058]Specifically, the hydration reaction of cement and modified ceramic polishing powder after water, forming a hydrated product, and the hydrated product contains Ca (OH) 2 Solution, CA (OH) 2 The solution quickly reached saturated and precipitated crystals while forming a calcitocalite crystal and a hydrated calcium silicate gel.

[0059] In some embodiments, the preparation method of masonry mortar includes the steps of:

[0060] S100, the cement, modified ceramic polishing powder and sand are physically stirred, and the mixture is evenly obtained.

[0061] S...

Example Embodiment

[0093] Example 1

[0094] 32 kg of composite silicate PC32.5, 15 kg modified ceramic polishing powder, 6.5 kg of heavy calcium and 34 kg of fineness modulus of 2.8 were physically stirred, stirred for 1min to obtain a first mixture;

[0095] 32 kg of water was added to the first mixture, stirred for 1min, and even the second mixture was obtained;

[0096] To the second mixture was added 1.7 kg of polycarboxylic acid water water water and 1.6 kg of a thickening agent for 3 min reaction to prepare masonry mortar;

[0097] Among them, the activity of modified ceramic polishing powder> 65%, specific surface area> 1023m 2 / kg, density> 2.56g / cm 3 ;

[0098] The fineness modulus of sand is 2.6-3.0;

[0099] The water reduction efficiency of the polycarboxylic acid water decrease is 36%.

Example Embodiment

[0100] Example 2

[0101] 28 kg of composite silicate cement PC32.5, 18 kg modified ceramic polishing powder, 6.8 kg of heavy calcium and 32 kg of fineness modulus of 2.6 were physically stirred, stirred for 0.5min, and obtained the first mixture;

[0102] 34 kg of water was added to the first mixture, stirred 1.5 min, and even the second mixture was obtained;

[0103] To the second mixture was added 1.6 kg of polycarboxylic acid water water repellent and 1.7 kg of a thickening agent to stir MIN reaction to prepare masonry mortar;

[0104] Among them, the activity of modified ceramic polishing powder> 65%, specific surface area> 1023m 2 / kg, density> 2.56g / cm 3 ;

[0105] The fineness modulus of sand is 2.6-3.0;

[0106] The water reduction efficiency of the polycarboxylic acid water decrease is 36%.

Abstract

The invention relates to masonry mortar and a preparation method thereof, and the masonry mortar is prepared from the following raw materials in parts by weight: 25-35 parts of cement; 10-20 parts of modified ceramic polishing powder; 28 to 38 parts of sand; 1-2 parts of a polycarboxylate superplasticizer; 1-2 parts of a thickening agent; water; modifying the activity gt of the ceramic polishing powder; 65%. According to the masonry mortar and the preparation method thereof provided by the invention, the modified ceramic polishing powder is used for replacing fly ash and mineral powder in the masonry mortar, so that the stability of the performance of the masonry mortar is improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a masonry mortar and a preparation method thereof. Background technique [0002] Masonry mortar is currently the main material for building bricks, stones, blocks and other blocks into masonry. It plays the role of bonding, lining and force transmission in masonry, and is widely used in construction. Masonry mortar is mainly composed of cementitious materials and fine aggregate, and the cementitious materials are often composed of cement and admixtures. [0003] Conventional admixtures are often used in existing masonry mortars, which are derived from by-products (mineral powder and fly ash, etc.) produced by electric fields and steel mills. The product quality of the by-product fly ash and slag has also fluctuated greatly, resulting in the product quality of fly ash and slag (fineness of fly ash and slag, content of powder vitreous body, content of fly ash carbon co...
