Problems solved by technology

[0002] In the construction of the antique city wall, the existing cement mortar and lime mortar are used to test the joints. After testing the effect of 10 meters of joints, there are three shortcomings: one is not smooth, there are burrs, and there are cracks.
Second, poor water resistance, large shrinkage, low bond strength, and poor durability
The third is that the color difference with the cyan fly ash city wall brick is too large and unsightly
Comprehensive analysis of cement mortar has its own shortcomings, namely poor workability, high bleeding rate, high cement dosage, fast hardening, easy cracking, low strength of lime mortar, poor water resistance, large shrinkage, and poor durability

Embodiment Construction

[0020] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0021] A new type of antique city wall jointing mortar, the jointing mortar includes components and their weight ratios are: fly ash 60Kg; cement 40Kg; sand 180Kg, fly ash is the original dry row fly ash, cement adopts 32.5# slag Portland cement, the sand is fine and medium sand.

[0022] A new antiquity city wall pointing mortar pointing method, the steps of the pointing method are:

[0023] ⑴. Use a flat chisel and a hammer to slit the seams of the brick wall that has been built, and use a broom to clean the slag from the slits;

[0024] ⑵. Spray the cleaned wall with a watering can, and after drying, fill the opening with a new type of antique city wall pointing mortar;

[0025] ⑶. The prepared new type of antique city wall pointing mor...

Abstract

The invention relates to novel imitation antique city wall pointing mortar and a pointing method of the novel imitation antique city wall pointing mortar. The pointing mortar comprises the following components in parts by weight: 60 parts of fly ash, 40 parts of cement, and 180 parts of sand, wherein the fly ash is an original-state dry discharged fly ash, the cement is No.32.5 slag portland cement, and the sand is fine-to-medium sand. The pointing mortar disclosed by the invention has the advantages of small fly ash / cement dry shrinkage, good workability, low hydration heat, high late intensity, good sulfate corrosion resistance, and the like. In the aspect of environmental protection, waste fly ash of power plants can be effectively used, and the cement can be saved, thereby achieving the effect of energy conservation and environmental protection. The cost is reduced, the benefit is improved, and the economic benefit of enterprises is increased.

Description

technical field [0001] The invention belongs to the field of mortar, in particular to a novel antique city wall pointing mortar and a pointing method thereof. Background technique [0002] In the construction of the antique city wall, the existing cement mortar and lime mortar were used to test the pointing. After testing the 10-meter pointing effect, there are three shortcomings: first, it is not smooth, there are burrs, and there are cracks. The second is poor water resistance, large shrinkage, low bond strength, and poor durability. The third is that the uncoordinated color difference with the cyan fly ash city wall brick is too large and unsightly. Comprehensive analysis of cement mortar has its own shortcomings, that is, poor workability, high bleeding rate, high cement dosage, fast hardening, and easy cracking, and lime mortar has low strength, poor water resistance, large shrinkage, and poor durability. Contents of the invention [0003] The purpose of the present...
