Embodiment 1

[0023] A method for preventing and curing efflorescence on stone paving, the method includes the following steps:

[0024] (1) Clean the stone, air dry or dry it;

[0025] (2) Pull wires to find the level of the ground where the stone is to be laid;

[0026] (3) Mix well with 3 parts of calcium silicate, 8 parts of gypsum, 5 parts of polished brick waste powder, 0.3 parts of hydration accelerator, 35 parts of kaolin, 3 parts of calcium carbide slag powder, 3 parts of water repellent and 5 parts of bentonite The prepared white cement with low content of calcium silicate is evenly applied to the back of the stone to form an adhesive layer;

[0027] (4) Lay the stone according to the design, and then use a wooden hammer to knock and vibrate the stone;

[0028] (5) After the stone paving is completed, the splicing gaps between the stones are cleaned, and the gaps between the stones are filled with melted paraffin;

[0029] (6) Apply waterproofing agent to the stone surface.

Embodiment 2

[0031] A method for preventing and curing efflorescence on stone paving, the method includes the following steps:

[0032] (1) Clean the stone, air dry or dry;

[0033] (2) Pull wires to find the level of the ground where the stone is to be laid;

[0034] (3) Fully mix with 6 parts of calcium silicate, 11 parts of gypsum, 7 parts of polished brick waste powder, 0.7 parts of hydration accelerator, 39 parts of kaolin, 8 parts of calcium carbide slag powder, 5 parts of water repellent and 8 parts of bentonite The prepared white cement with low content of calcium silicate is evenly applied to the back of the stone to form an adhesive layer;

[0035] (4) Lay the stone according to the design, and then use a wooden hammer to knock and vibrate the stone;

[0036] (5) After the stone paving is completed, the splicing gaps between the stones are cleaned, and the gaps between the stones are filled with melted paraffin;

[0037] (6) Apply waterproofing agent to the stone surface.

Embodiment 3

[0039] A method for preventing and curing efflorescence on stone paving, the method includes the following steps:

[0040] (1) Clean the stone, air dry or dry;

[0041] (2) Pull wires to find the level of the ground where the stone is to be laid;

[0042] (3) Fully mix with 9 parts of calcium silicate, 15 parts of gypsum, 10 parts of polished brick waste powder, 1 part of hydration accelerator, 42 parts of kaolin, 13 parts of calcium carbide slag powder, 7 parts of water repellent and 10 parts of bentonite The prepared white cement with low content of calcium silicate is evenly applied to the back of the stone to form an adhesive layer;

[0043] (4) Lay the stone according to the design, and then use a wooden hammer to knock and vibrate the stone;

[0044] (5) After the stone paving is completed, the splicing gaps between the stones are cleaned, and the gaps between the stones are filled with melted paraffin;

[0045] (6) Apply waterproofing agent to the stone surface.

Abstract

The invention discloses a saltpetering prevention method for stone paving, and relates to the technical field of stone paving. The method includes the following steps that stones are cleaned, air-dried or oven-dried; the ground on which the stones needs to be paved is subjected to leveling through a stay wire; the back surfaces of the stones are uniformly coated with white cement with the same labels but low in calcium silicate content, and a bonding layer is formed; the stones are paved according to the design, and then a wooden hammer is used for knocking and compaction of the stones; afterthe stones are paved, the splicing gaps among the stones are cleaned, and melted paraffin is used for filling the gaps among the stones; the surfaces of the stones are coated with a waterproof agent.Through the disclosed stone paving steps and method and the composition of white cement, the saltpetering phenomenon on the surfaces of the stones is effectively reduced, the aesthetic feeling of thestones is increased and disturbance from people is reduced.

Description

technical field [0001] The invention belongs to the technical field of stone paving, in particular to a method for preventing and curing efflorescence of stone paving. Background technique [0002] With the improvement of people's living standards, people's demand for stone decoration for home life is also increasing, but as time accumulates, the surface of stone is not easy to clean, especially when it encounters humid air, the surface of stone is easy to clean. Alkali will seriously affect the beauty of stone. [0003] In the process of stone paving, it is often necessary to apply cement products, but the calcium silicate (chemical salt) in cement products is prone to hydration reaction after contact with water, forming free calcium, silicic acid and hydroxide. The lack of compactness determines that cement products have a certain moisture content. When the cement product contains water, the water can rise along the capillary pores inside the stone. At this time, the che...
