Plastering gypsum mortar is a newer, more environment-friendly and more economical product instead of cement mortar, which is now a key promotion product. The strength of these two kinds of cement is healthier, more environment-friendly and durable than cement. The adhesive is not easy to powder, crack, empty, not powder and other advantages. It is easy to use and cost saving. The wholesale cost of Jinan gypsum powder is analyzed as follows:

　　從單價(jià)上看，石膏砂漿比水泥砂漿貴，但石膏砂漿有很多優(yōu)點(diǎn)，綜合下來，濟(jì)南石膏粉每平方米的造價(jià)比水泥砂漿低:

　　In terms of unit price, gypsum mortar is more expensive than cement mortar, but gypsum mortar has many advantages. In a word, the cost per square meter of Jinan gypsum powder is lower than that of cement mortar1. 基本解決了空鼓、裂縫、抹灰層脫落等問題。同時(shí)，縮短抹灰周期，比傳統(tǒng)水泥砂漿抹灰工藝提率1.5-2倍。

　　1. The problems of hollowing, crack and falling off of plastering layer are basically solved. Meanwhile, the plastering cycle is shortened, and the efficiency is 1.5-2 times higher than that of traditional cement mortar plastering process.

　　2、石膏石膏砂漿體積密度在1㎏/ L - 1.3㎏/ L,水泥石灰漿體積重量在1.7㎏/ L - 1.8㎏/ L,在石膏與13 -14毫米,厚度1 t石膏石膏混合漿可以擦75㎡-80㎡,和水泥石灰混合砂漿抹45㎡-48㎡。

　　2. The volume density of gypsum gypsum mortar is 1kg / L - 1.3kg/l, and the volume weight of cement lime slurry is 1.7kg / L - 1.8kg/l. In gypsum and 13-14mm, the thickness of 1t gypsum gypsum mixed slurry can be wiped 75 ㎡ - 80 ㎡, and the cement lime mixed mortar can be wiped 45 ㎡ - 48 ㎡.

　　3、100㎡的高質(zhì)量墻裝飾,需要勞動定額的過程操作,石膏混合與勞動定額83.4 h,水泥和石灰混合與勞動定額167.2 h。兩種石膏砂漿的對比減少了大量的操作過程，幫助節(jié)省了約1倍的勞動力消耗。

　　3. The 100 ㎡ high-quality wall decoration needs the process operation of labor quota. The gypsum mixing and labor quota are 83.4 h, and the cement and lime mixing and labor quota are 167.2 H. The comparison of two kinds of gypsum mortar reduces a lot of operation process, and helps to save about one time of labor consumption.

　　4、可從混凝土表面去除切割技術(shù)，縮短抹灰周期。

　　4. The cutting technology can be removed from the concrete surface to shorten the plastering cycle.

　　5、在石膏抹灰砂漿封面表面裝飾,可以節(jié)省裝飾涂料和涂膠,與106年一般墻面涂料等0.3㎏/㎡-0.5㎏/㎡,106年和灰泥墻面涂料是0.2㎏/㎡-0.3㎏/㎡。

　　5. The decoration on the cover surface of gypsum plastering mortar can save decorative coating and glue application. Compared with the general wall coating in 106 years, 0.3 kg / ㎡ - 0.5 kg / ㎡, and the plaster wall coating in 106 years is 0.2 kg / ㎡ - 0.3 kg / ㎡.

　　6、抹灰砂漿早強(qiáng)快硬，適用于施工期。

　　6. The plastering mortar is early strength and fast hardening, which is suitable for the construction period.

　　7、石膏砂漿具有較強(qiáng)的粘結(jié)性，基本消除空鼓、開裂，減少返工。

　　7. Gypsum mortar has strong cohesiveness, basically eliminating hollowing and cracking, reducing rework.

　　8、石膏砂漿施工揚(yáng)塵少，減少材料浪費(fèi)和清潔勞動。

　　8. Gypsum mortar construction dust less, reduce material waste and clean labor.

　　9、石膏比砂漿更適合水泥攪拌砂的冬季施工，可以節(jié)省大量的冬季施工保溫費(fèi)用。

　　9. Gypsum is more suitable for winter construction of cement mixing sand than mortar, which can save a lot of heat preservation cost in winter construction.

　　10. 石膏砂漿是一類防火材料，可以提高建筑的防火、隔音和保溫性能。

　　10. Gypsum mortar is a kind of fire-proof material, which can improve the performance of fire prevention, sound insulation and heat preservation of buildings.

　　11、石膏砂漿的銷售價(jià)格似乎感覺比較貴，但在工程應(yīng)用中，綜合成本并不比傳統(tǒng)抹灰材料貴。例如:石膏砂漿抹灰層厚度可以小于3mm，水泥砂漿抹灰層厚度需要在6mm-8mm以上。

　　11. The selling price of gypsum mortar seems to be relatively expensive, but in engineering application, the comprehensive cost is not more expensive than that of traditional plastering materials. For example: the thickness of gypsum mortar plastering layer can be less than 3mm, and the thickness of cement mortar plastering layer needs to be more than 6mm-8mm.

　　總之,濟(jì)南石膏粉的使用可以減少工程造價(jià)10 - 15%,并減少返工、浪費(fèi)現(xiàn)象,是一種新的高品質(zhì)環(huán)保產(chǎn)品的技術(shù)開發(fā),經(jīng)濟(jì)效益和社會效益顯著,對許多國家的政策建議,成為新的更喜歡的大多數(shù)用戶,將取代水泥砂漿的地方。

　　In short, the use of Jinan gypsum powder can reduce the project cost by 10 - 15%, and reduce the phenomenon of rework and waste. It is a new high-quality environmental protection product technology development, with significant economic and social benefits. Policy recommendations for many countries have become the new favorite place for most users, which will replace cement mortar.
