Classification of mortar grades summarized by manufacturers of hydroxypropyl methylcellulose

Hydroxypropyl methyl cellulose manufacturer Shandong chuangyao Biotechnology Co., Ltd. summarized and introduced the mortar grade and classification.

1. Mortar can be divided into ready mixed mortar (commercial mortar) and job mixed mortar according to the application form;

According to the cementing materials used, they can be divided into cement, gypsum, lime, water glass and phosphate;

According to the use function, it can be divided into structural mortar, functional mortar and decorative mortar. Structural mortar is used for masonry, plastering, bonding, anchoring, interface treatment, non load-bearing components, etc., which can be divided into different strength grades according to the compressive strength; functional mortar can be used for thermal insulation, fire prevention, waterproof, repair, etc.; decorative mortar can be used for external wall, internal wall, ground, etc.; according to the construction method, it can be divided into manual troweling and mechanical spraying.

2. Ready mixed mortar code f

Dry mixed mortar code D wet mixed mortar code w

3. Job mix mortar code s

4. Masonry mortar code m dry mix masonry mortar DM wet mix masonry mortar WM dry mix masonry mortar according to the different water absorption characteristics of masonry materials, it can be divided into: high water retention masonry mortar code dm-hr, used for aerated concrete block and fired brick; medium water holding masonry mortar code dm-mr, used for ordinary concrete block and light concrete block; Low water retention masonry mortar code dm-lr, used for lime sand brick.

5. Plastering mortar Code: P dry mixed plastering mortar Code: DP;

Wet mixed plastering mortar Code: WP; According to the different water absorption characteristics of base materials, dry mixed plastering mortar can be divided into: high water retention plastering mortar code dp-hr, used for aerated concrete wall and fired brick wall; medium water holding masonry mortar code named dp-mr, used for ordinary concrete block and light concrete block wall, light concrete slab wall, cast-in-place concrete wall; low water retention masonry mortar- ---Code dp-lr, used for lime sand brick wall. According to the plastering mortar with cementitious material: plaster --- code dp-g. According to the thickness of plastering mortar: putty --- Code: DSP.

6. Floor leveling mortar code s dry mixed floor leveling mortar code ds;

Wet mixed ground leveling mortar Code: WS; cement-based self leveling mortar: Code: SLF; self leveling gypsum: Code: slf-g.

7, foam polystyrene board thin plastering exterior wall external thermal insulation system special dry mixed adhesive mortar - Code DEA; foam polystyrene board thin plastering external wall insulation system with dry mixing mortar mortar - - Code DBI.

8. Ceramic tile adhesive code DTA; ceramic tile jointing agent code DTG.

9. Interface treatment agent code name DB: the initial bonding layer is formed in a "multilayer" system, usually in the form of a thin layer.

10. Dry mixed colored mortar: Code: DC.

11. Dry mixed water proofing mortar: mortar to prevent water from seeping into the bottom layer under the specified pressure, code name DWP.

12. Dry mixed repair mortar: mortar used to repair or replace defective concrete, which can be structural mortar or non structural mortar, code name Dr.

13. Dry mixed anchoring mortar: for mortar with code da not listed in the above classification number, the following Numbering Rules shall be adopted: English abbreviation of d-mortar function strength mark water retention cementitious material type 2、 Change of material and construction method 1. Replacement of dry mixed mortar strength mark and mix proportion of job mix mortar: dm-5, replace 1:1:6 mixed mortar, 1:4 cement mortar DM-10, replace 1:0.5:3 mixed mortar and 1:3 cement mortar; dm-15, replace 1:1:4 mixed mortar and 1:2.5 cement mortar; DM-20, replace 1:2 cement mortar. 2. According to the above classification, the mixed mortar and cement mortar prepared on site in "88j1-1 engineering practice" and "88j1-3 engineering practice (2)" are replaced according to the above classification. Due to the unstable source and quality of building slaked lime, the content of lime mortar is cancelled. 3. Due to the strict requirements of bond strength between dry mixed mortar and base material, and between dry mixed mortar and dry mixed mortar, the so-called "construction adhesive" has no way to strictly control its on-site quality, and the practices of "one course of plain cement paste (mixed with construction glue)" and "construction adhesive cement mortar" are cancelled. 4. Due to the above reasons, the construction method of mortar layer has also been replaced, merged and simplified, and the thickness has also been reduced accordingly, so as to give full play to the effect of dry mixed mortar in saving resources, protecting environment, improving construction quality, realizing civilized construction and promoting modernization of construction.
