Description

Technical Field

[0001] The invention belongs to the technical field of mortar curing, and specifically relates to a mortar curing process. Background Art

[0002] Mortar is the bonding material used for brick and stone laying in construction. Mortar curing refers to the process from the beginning of mortar stirring to its gradual hardening. Mortar curing time refers to the time from the beginning of mortar stirring to its hardening. Usually, the time when the mortar is mixed until it is evenly mixed is marked as the starting time. When the moisture in the mortar gradually evaporates or is absorbed, and the mortar gradually hardens and cannot be processed with tools, it is marked as the curing time.

[0003] The traditional mortar curing process has the following shortcomings: the quality and moisture content of the raw materials of the mortar in the traditional mortar curing process, such as cement, sand, etc., are often unstable, which directly affects the curing time and curing effect of the mortar. The mortar may dehydrate too quickly during the construction process, resulting in surface dryness and cracking; at the same time, it may also cause alkali efflux due to excessive absorption of moisture. Therefore, a curing agent needs to be added to adjust the moisture balance of the mortar to prevent it from dehydrating too quickly or absorbing too much moisture. Summary of the invention

[0004] The object of the present invention is to provide a mortar curing process to solve the problems raised in the above background technology.

[0005] In order to achieve the above object, the present invention provides the following technical solution: a mortar curing process, comprising the following raw material components in parts by weight:

[0007] 20 kg water;

[0008] Aggregate 80 kg;

[0009] 6 kg of curing agent.

[0010] Preferably, the aggregate is a mixture of quartz sand, lignite and sand in a weight ratio of 4:2.5:3.5.

[0016] A4. Apply mortar: Apply the prepared mortar on the surface of the building structure. The thickness should be controlled within a certain range. Apply the mortar in layers as needed, and each layer should be firmly bonded to each other.

[0017] A5. Wait for curing: After the mortar is applied, wait for it to cure naturally. During the curing process, the temperature and humidity of the construction environment should be kept appropriate to avoid the mortar curing too quickly or too slowly.

[0018] A6. Inspection and repair: Inspect the solidified mortar to ensure that its quality and effect meet the construction requirements.

[0024] Preferably, said A2 comprises the following steps:

[0025] B1. Weighing materials: Use accurate weighing tools to weigh silicate, calcium oxide and EDTA respectively, making sure the weight of each material meets the ratio of 2:1:1;

[0026] B2. Mix silicate and calcium oxide: Carefully mix silicate and calcium oxide in a clean, dry and non-reactive container. Use an electric stirrer to mix the two materials thoroughly.

[0027] B3. Add EDTA: gradually add the weighed EDTA to the mixture of silicate and calcium oxide, and continue stirring to ensure that the EDTA is evenly dispersed in the mixture.

[0028] B4. Mix well: Continue to stir the mixture until all ingredients are fully mixed and uniform curing agent powder is formed.

[0029] Preferably, the suitable temperature range for curing of the mortar is generally between 5° C. and 40° C., and the mortar should be applied in layers during the application process.

[0030] Preferably, the coating thickness of the bottom layer is in the range of 5 to 7 mm, the thickness of the middle layer is no more than 12 mm, and the thickness of the surface layer is in the range of 2 to 5 mm.

[0034] 3. The present invention adopts a layered coating method, so that the bonding between each layer of mortar is more solid, which not only ensures the construction quality but also improves the construction efficiency. In addition, the process also pays attention to the conservation and environmental protection of raw materials, and reduces waste and pollution by accurately controlling the amount of raw materials and the preparation process. At the same time, the addition of curing agent adjusts the moisture balance of the mortar, reduces the need for later maintenance and repair, and reduces the overall cost of the construction project. The application of this process not only promotes the green development of the construction industry, but also provides a strong guarantee for the high-quality completion of construction projects. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Figure 1 This is a flow chart of the mortar curing process of the present invention. DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1

[0038] The embodiment of the present invention provides a mortar curing process, comprising the following raw material components in parts by weight:

[0039] 50 kg cement;

[0040] 20 kg water;

[0041] Aggregate 80 kg;

[0042] 6 kg of curing agent.

[0043] In this example, cement, as the main cementitious material, reacts with an appropriate amount of water to form cement stone, which firmly bonds the aggregates together and provides high strength for the cement mortar. The aggregate is made of quartz sand, lignite and sand mixed in a certain proportion, has high hardness and wear resistance, and can enhance the compressive and flexural strength of the cement mortar. The curing agent is a mixture of silicate, calcium oxide and ethylenediaminetetraacetic acid (EDTA), which can accelerate the hydration process of cement, promote the early strength development of the cement mortar, and improve the durability and impermeability of the cement mortar.

[0044] Example 2

[0045] The aggregate is a mixture of quartz sand, lignite and sand in a weight ratio of 4:2.5:3.5.

[0046] In this example, the quartz sand, lignite and sand have different particle sizes. By mixing them in a certain proportion, they can effectively fill the gaps and improve the density and uniformity of the overall mixture. Quartz sand has high hardness and wear resistance, which can increase the overall strength of the mixture. Although lignite is soft in texture, it can also play a filling and bonding role to a certain extent. Together with quartz sand and sand, it can form a more compact structure.

[0047] Example 3

[0048] The curing agent is a mixture of silicate, calcium oxide and ethylenediaminetetraacetic acid in a weight ratio of 2:1:1.

[0049] In this case, as the main curing agent component, the content of silicate directly affects the hardening speed and final strength of cement mortar. It can react with calcium hydroxide in cement to form calcium silicate gel, thereby improving the strength and durability of concrete; calcium oxide plays a promoting role in the curing process and helps the hydration reaction of silicate. The right amount of calcium oxide can improve the early strength of cement mortar and accelerate the hardening speed.

[0050] Example 4

[0051] The following steps are involved:

[0052] A1. Base treatment: Clean the surface of the building structure, remove impurities such as oil, dust, etc., polish and treat the surface to improve the adhesion of the mortar;

[0053] A2. Preparation of curing agent: Mix silicate, calcium oxide and ethylenediaminetetraacetic acid in a weight ratio of 2:1:1;

[0054] A3. Mortar production: Mix cement, lime and sand in a certain proportion; add appropriate amount of water and curing agent and stir until the mortar is uniform, fine and easy to apply;

[0055] A4. Apply mortar: Apply the prepared mortar on the surface of the building structure. The thickness should be controlled within a certain range. Apply the mortar in layers as needed, and each layer should be firmly bonded to each other.

[0056] A5. Wait for curing: After the mortar is applied, wait for it to cure naturally. During the curing process, the temperature and humidity of the construction environment should be kept appropriate to avoid the mortar curing too quickly or too slowly.

[0057] A6. Inspection and repair: Inspect the solidified mortar to ensure that its quality and effect meet the construction requirements.

[0058] In this case, it can ensure the surface cleanliness of the building structure and improve the adhesion of the mortar; accurately make the curing agent and mortar to ensure the material performance; apply the mortar in layers to enhance the strength and durability of the structure; control the construction environment to ensure that the mortar is suitable for curing; and finally conduct inspections and repairs to ensure the quality of construction. This series of standardized processes can effectively improve the quality of mortar construction, enhance the safety and stability of the building structure, and at the same time improve construction efficiency and material utilization.

[0059] Example 5

[0060] A3 includes the following steps:

[0061] S1. Preparation: Prepare the required materials in advance: cement, water, sand and curing agent; prepare the required tools in advance: mixing bucket and scale;

[0062] S2. Material preparation: Use a scale to weigh and place the materials in proportion, and then place the required materials in sequence;

[0063] S3. Add curing agent: add 20 kg of water to a 200L mixing bucket, and stir at 200 rpm at room temperature; then add 6 kg of curing agent to the 200L mixing bucket, and stir the curing agent and water thoroughly to ensure that the curing agent is completely dissolved or dispersed in the water;

[0064] S4. Prepare mortar: add 32 kg of quartz sand, 20 kg of lignite and 28 kg of sand while stirring, stir evenly to form a premix, and take it out.

[0065] In this case, this step can ensure that the materials are accurately proportioned and the curing agent is fully dissolved, so that the produced mortar has high strength and good durability, and the construction process is standardized and efficient.

[0066] Example 6

[0067] A2 includes the following steps:

[0068] B1. Weighing materials: Use accurate weighing tools to weigh silicate, calcium oxide and EDTA respectively, making sure the weight of each material meets the ratio of 2:1:1;

[0069] B2. Mix silicate and calcium oxide: Carefully mix silicate and calcium oxide in a clean, dry and non-reactive container. Use an electric stirrer to mix the two materials thoroughly.

[0070] B3. Add EDTA: gradually add the weighed EDTA to the mixture of silicate and calcium oxide, and continue stirring to ensure that the EDTA is evenly dispersed in the mixture.

[0071] B4. Mix well: Continue to stir the mixture until all ingredients are fully mixed and uniform curing agent powder is formed.

[0072] In this example, this step can ensure that the curing agent components are accurately proportioned and evenly mixed, thereby optimizing its chemical reaction performance and improving the strength, durability and construction performance of the cement mortar.

[0073] Example 7

[0074] The suitable temperature range for mortar curing is usually between 5℃ and 40℃, and the mortar should be applied in layers during the application process.

[0075] In this case, within this temperature range, the chemical reaction in the mortar can proceed normally and the curing speed is moderate, which is conducive to the mortar achieving the expected strength and durability.

[0076] Example 8

[0077] The thickness of the base layer ranges from 5 to 7 mm, the thickness of the middle layer does not exceed 12 mm, and the thickness of the surface layer ranges from 2 to 5 mm.

[0078] In this case, layered application allows each layer of mortar to better penetrate into the tiny gaps in the base layer, thereby increasing the contact area and bonding strength between the mortar and the base layer.
