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:

　　从单价上看，石膏砂浆比水泥砂浆贵，但石膏砂浆有很多优点，综合下来，济南石膏粉每平方米的造价比水泥砂浆低:

　　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. 基本解决了空鼓、裂缝、抹灰层脱落等问题。同时，缩短抹灰周期，比传统水泥砂浆抹灰工艺提率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、石膏石膏砂浆体积密度在1㎏/ L - 1.3㎏/ L,水泥石灰浆体积重量在1.7㎏/ L - 1.8㎏/ L,在石膏与13 -14毫米,厚度1 t石膏石膏混合浆可以擦75㎡-80㎡,和水泥石灰混合砂浆抹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㎡的高质量墙装饰,需要劳动定额的过程操作,石膏混合与劳动定额83.4 h,水泥和石灰混合与劳动定额167.2 h。两种石膏砂浆的对比减少了大量的操作过程，帮助节省了约1倍的劳动力消耗。

　　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、可从混凝土表面去除切割技术，缩短抹灰周期。

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

　　5、在石膏抹灰砂浆封面表面装饰,可以节省装饰涂料和涂胶,与106年一般墙面涂料等0.3㎏/㎡-0.5㎏/㎡,106年和灰泥墙面涂料是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、抹灰砂浆早强快硬，适用于施工期。

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

　　7、石膏砂浆具有较强的粘结性，基本消除空鼓、开裂，减少返工。

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

　　8、石膏砂浆施工扬尘少，减少材料浪费和清洁劳动。

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

　　9、石膏比砂浆更适合水泥搅拌砂的冬季施工，可以节省大量的冬季施工保温费用。

　　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. 石膏砂浆是一类防火材料，可以提高建筑的防火、隔音和保温性能。

　　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、石膏砂浆的销售价格似乎感觉比较贵，但在工程应用中，综合成本并不比传统抹灰材料贵。例如:石膏砂浆抹灰层厚度可以小于3mm，水泥砂浆抹灰层厚度需要在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.

　　总之,济南石膏粉的使用可以减少工程造价10 - 15%,并减少返工、浪费现象,是一种新的高品质环保产品的技术开发,经济效益和社会效益显著,对许多国家的政策建议,成为新的更喜欢的大多数用户,将取代水泥砂浆的地方。

　　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.
