preparation example Construction

[0024] The preparation methods of Examples 1 to 8 are as follows: Step 1, various solid raw materials are classified and stacked, and after drying and screening, each raw material is weighed according to the mass ratio;

[0025] Step 2, adding sand and electric slag to the cement and stirring evenly, then adding crushed material and dry powdered lime, and continuously stirring to obtain a uniformly dispersed mixed material;

[0026] Step 3: add sludge, silt and dry powder latex to the mixed material in sequence and continue to stir until uniformly dispersed, then put into a pulverizer and pulverize into fine particles or powder, and mix well to obtain a composite building mortar.

[0027] Examples 1 to 4 use wet methods: add composite construction mortar to water, stir evenly to obtain slurry, and then evenly coat the slurry on the wall.

[0028] Examples 5 to 8 use the dry method: evenly sprinkle the composite construction slurry on the wet painted surface, floor or construct...

Embodiment 5- Embodiment 8

[0033]

[0034] Example 1-Example 4, the slurry was obtained according to the above mass ratio and preparation method, and then the slurry was evenly coated on the construction surface. The construction is carried out according to the requirements, and the setting time, strength time and maintenance period are 28 days, which can meet the project quality requirements.

[0035] After the mortar is mixed with water, its service time requirements are as follows: the ambient temperature is 0°C-10°C, it should be used up within 5 hours; the ambient temperature is 10°C-20°C, it should be used up within 3 hours, and the ambient temperature is 20°C-20°C. 30°C, it should be used within 2 hours; the ambient temperature is 30°C-37°C, it should be used within 1 hour; the mortar should be properly stirred to increase its mobility.

[0036] According to the ordinary Portland cement used, the strength of Example 1-Example 4 can be divided into four grades: Ⅰ (M5.0 strength), Ⅱ (M7.5 streng...

Abstract

The invention belongs to the technical field of building materials, and particularly relates to an energy-saving dry and wet dual-use composite building mortar. The composite building mortar comprises, by mass, 260-410 parts of cement, 500-700 parts of sands, 8-50 parts of electric furnace slag, 10-100 parts of crushed aggregates, 5-20 parts of dry powdered lime, 2-5 parts of sludge, 2-5 parts of silt and 12-35 parts of dry powder latex; and the crushed aggregates adopt chippings or rubbles. The dry powder latex is used as a polymer material to effectively improve the cross-section performance, and the flexibility of the dry powder latex is combined to easily carry out accurate measurement and improve the construction convenience, so the construction quality can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an energy-saving dry-wet dual-purpose composite building mortar. Background technique [0002] Traditional mortar is an on-site mixing product, and its measurement accuracy is difficult to control, resulting in great fluctuations in mortar quality. In addition, the raw materials of traditional mortar are single in nature. During the coagulation and hardening process, water evaporation will form more pores; at the same time, the shrinkage function of the cement-based hardened body and the wall is quite different, so the interface between the wall and the mortar is not uniform. High stress is distributed in the ground, which is in a state of thermodynamic imbalance and tends to be evenly distributed spontaneously. Under this force and the force of the outside world, it often causes wall cracking and water seepage; the plastering layer swells , Shedding and o...
