Embodiment 1

[0032] Type A preparation: 50% cement, 12.5% ​​slaked lime, 37.25% heavy calcium as mineral admixture, 0.2% water-retaining agent as additive, and 0.05% air-entraining agent as additive. Mix well to make cement mixture. Class B: Screened, washed (not dried) sand.

[0033] Transport the above two types of raw materials A and B to the construction site respectively, dry mix 40% cement mixture and 60% sand, and then add water with 10-20% solid content for wet mixing to make masonry mortar , for building construction.

[0034] The stated percentages are percentages by weight, the same below.

Embodiment 2

[0036] Type A preparation: 62.5% cement, 12.5% ​​slaked lime, 24.83% heavy calcium as mineral admixture, 0.1% water-retaining agent as additive, 0.05% starch ether as additive, and 0.02% air-entraining agent. Mix well to make cement mixture. Type B: Screen washed (undried) sand.

[0037] The above-mentioned two types of raw materials A and B are divided into sub-tanks and mother tanks of storage and transportation containers in the form of sub-mother tanks and transported to the construction site, dry-mixing 40% of the cement mixture and 60% of the sand, adding 10-20% of the solid content is wet-mixed with water to make plastering mortar for building construction.

[0038] The weighing batching, dry mixing, and wet mixing of A and B two types of raw materials are completed in a compound mixing equipment; the compound mixing equipment includes a dry mixer and a wet mixer located below the dry mixer, and the dry mixer The discharge port of the wet mixer is located directly abo...

Embodiment 3

[0040] Type A preparation: cement 97.3%, redispersible latex powder 0.9%, water retaining agent 0.3%, water reducing agent 0.9%, defoamer 0.6%. Mix well to make cement mixture. Type B: Screen washed (undried) sand.

[0041] The above two types of raw materials, A and B, are packed in sub-tanks and mother tanks of specific storage and transportation containers and transported to the construction site, such as figure 1 The storage and transportation container of this specific form comprises a mother tank 1 with a mother tank outlet 4 at the lower end, and at least one cylindrical sub-tank 2 is fixedly installed in the main tank 1, and the sub-tank 2 and The mother tanks 1 have feeding ports respectively. The lower end of the sub-tank 2 has a sub-tank discharge port 11. In order to facilitate discharging into the feed hopper 5-2, the sub-tank discharge port 11 and the mother tank discharge port 4 are close to each other and both Located directly above the feed hopper 5-2. The...

Abstract

The invention discloses a storage, transportation and mixed preparation method for building mortar and a special device thereof. The method comprises the following steps of: firstly, dividing the raw materials of dry-mixed mortar into a cement mixed material and sand, and transporting the two raw materials to a construction site by virtue of mutually independent containers; and then, at the construction site, respectively weighing a raw material A and a raw material B, and carrying out dry mixing and wet mixing on the raw material A and the raw material B. The method and the special device overcome the defect of high energy consumption due to the baking of the sand in the existing manufacturing and using processes of the mortar, save energy resources, solve the separation problem in the existing production and transportation processes of the mortar, and improve the product quality on the premise that the energy resources are saved.

Description

technical field [0001] The invention relates to a method for storage, transportation and mixing of building mortar and special equipment for realizing the method. Background technique [0002] Cement mortars for construction are traditionally manufactured and used by mixing the components at the construction site. The disadvantages are: first, serious dust and noise pollution; second, the quality is not easy to control; third, the material stacking occupies a large area. Therefore, more than 90% of developed countries have abandoned this on-site mixing method, and use specialized and commercialized ready-mixed dry-mixed mortar. [0003] The current production and use methods of commercial dry-mixed mortar are: in the dry-mixed mortar manufacturing plant, cement, mineral admixtures, lime or gypsum, additives, and sand after drying (moisture content less than 0.5%) are mixed to make The dry-mixed mortar leaves the factory and is wet-mixed with water at the construction site ...
