Problems solved by technology

[0007] With the popularity of ready-mixed mortar and the depletion of natural sand resources, most construction projects began to use machine-made sand as the aggregate of ready-mixed mortar. Poor operability of ready-mixed mortar often occurs in the base building mortar, which affects the construction efficiency. At the same time, it brings great difficulties to the popularization and application of ready-mixed mortar, which is not conducive to the development of the construction industry in the direction of energy conservation and environmental protection.
[0008] At present, during the actual construction, the construction performance of the construction mortar can only be transported to the construction site and evaluated by the construction personnel after use, which wastes a lot of time and energy. At the same time, it requires batches of construction mortar and skilled workers. It is greatly affected by subjective factors and can only be provided. Qualitative expression, unable to control in actual production

Embodiment 1

[0030] Embodiment 1 Utilizes the process of detection method of the present invention to measure cohesiveness

[0031] 1.1 Preparation of mortar

[0032] 1.1.1 When preparing mortar mixture in the laboratory, the materials used should be transported into the room 24 hours in advance. The temperature of the test chamber should be kept at (20±5)°C during mixing.

[0033] Note: When it is necessary to simulate the mortar used under the construction conditions, the temperature of the raw materials used should be consistent with that of the construction site.

[0034] 1.1.2 The raw materials used in the test should be consistent with those used on site. The machine-made sand should pass through a square hole sieve with a nominal particle size of 4.75mm in advance.

[0035] 1.1.3 When mixing mortar in the laboratory, the amount of materials should be measured by mass. Accurately weigh various materials, and its weighing accuracy: ±0.5% for cement, admixtures, admixtures, etc.; ±...

Embodiment 2

[0058] Embodiment 2 detection application example

[0059] The method of Example 1 was used to detect the average value of the degree of expansion of the cement mortar obtained by preparing the following material proportions, thereby judging its cohesiveness.

[0060] Table 2 Test results of application examples

[0061]

[0062] It can be seen from the above table that the performance of cement mortar can be judged quickly by using the detection method of the present invention, which provides standards for actual production and operation, and facilitates timely improvement of material formula to cope with changes in actual production conditions.

[0063] In summary, the method of the present invention is proposed and established for the first time to evaluate the cohesion of mortar, which provides a standard support for actual production, has strong feasibility and broad application prospects.

Abstract

The invention belongs to the field of cement mortar performance detection, and in particular relates to a method for measuring the cohesiveness of cement-based building mortar. The method is suitable for the detection of building mortar, especially for the detection of building mortar prepared from various machine-made sands. The technical problem solved by the invention is to provide a method for evaluating the cohesion of building mortar. The method comprises the following steps: A. preparation of mortar; B. measurement of water consumption of mortar; C. measurement of expansion degree of mortar. The measuring method of the present invention determines the target consistency that should be satisfied during actual production by measuring the water consumption of the mortar. Then use the measurement of mortar expansion to evaluate and control the cohesiveness of building mortar, and provide standard support for the actual production of mortar suitable for construction on construction sites; it is also conducive to the direct and objective evaluation of the operability of mortar cohesiveness .

Description

technical field [0001] The invention belongs to the field of cement mortar performance detection, and in particular relates to a method for measuring the cohesiveness of cement-based building mortar. The method is suitable for the detection of building mortar, especially for the detection of building mortar prepared from various machine-made sands. Background technique [0002] Construction mortar refers to a construction engineering material that is composed of inorganic cementitious materials, fine aggregates, admixtures, water, and other components determined according to performance, mixed in appropriate proportions, mixed and hardened. It mainly plays the role of bonding, padding and transferring stress. According to the production characteristics of mortar, it is divided into mortar mixed on the construction site and ready-mixed mortar produced by professional production plants. According to the use of mortar in construction engineering, it can be divided into masonry...
