【摘要】 文中在我国混凝土外加剂事业发展现状论证的基础上,提出了对M—G系列混凝土减水剂开发的前景展望。并对M—G系列混凝土减水剂的特点进行了综合论述。 M——G系列混凝土减水剂,由我院水利系研制,属国内首创,其工艺转化是极其复杂的化学转化,其产品也是极为复杂的具有多元极性基团的混合物,属阴离子表面活性剂,减水效果良好。本文对M—G系列减水剂制作机理进行了初步探讨。更多还原

【Abstract】 The Categery ef Crops Stalk: Corn-Stalk Sorglium-Stalk.Wheat-Strw The arm of Sunflower. The waste Waterials of Agricuture and Side Occupation:Corn-Core. The Plate of Sunflower The Waste Residue of the potate. The Categery of Weeds: Drunkard Horse-Crass. Puncture Vine. Siberian Cocklebur. Artemisia.Grass eet. 1.The raw materials are very rich rh. and beneficial to Protect environment. The price of the raw materials is low and the rate of products is higher. So the water Ruduce Asmixtures is lower. 2.The thirteen kinds of water Rudce Admiture all the technology Char acter each index comes up to or exceeds Ordinary water Reducing Admixtures and Set Retarding water Reducing Admixtues index that the Countxy Stipulates GB. 3.A Series M-G the breed of the Set Retarding Water Reducing Admixt ure is applicable to: Hydraulic and Hydroelectic Engineering. Bulk Mass Concrete. Chu ting Concrete. Concreting in hot Weather. Concreting in lifts.foun dation block. Civil Construction Agricuture Construction.ect. A Series M-G the breed of the Flash Selling water Reducing Admixturesis applicable to; High-Strength Concrete. The Close for Reinforcing Engineering. Be for hand Block work Cencrete ect. 4. The technological process is simpler. It is no poison no stink and little Contaminate. 5. A Series of M-G Water Reduce Admixture may be used Complexly: (a) It may be used complexly with the Superplasticizer may be achievedthe Superplasticizer s behaviour. (b) It may be wsed complexly with the X-Reduce Lose Admixture. Attanedone hour the lose smallest for caving scall. (c) It may be used complexly with the Hardening Accelerating Admixtur. achievex good results. On the other hand. text form organic chemistry point of view to probe into the technology make principle更多还原
