slag cement effect on set time of concrete in cameroon

At temperatures less than 85 degrees Fahrenheit concrete containing slag cement can have longer times of set when compared with 100 percent portland cement concrete The lower the ambient andor concrete temperatures the slower the set times will be Figure 1 The percentage of slag cement used can also affect times of set...We are a professional mining machinery manufacturer, the main equipment including: jaw crusher, cone crusher and other sandstone equipment;Ball mill, flotation machine, concentrator and other beneficiation equipment; Powder Grinding Plant, rotary dryer, briquette machine, mining, metallurgy and other related equipment. which can crush all kinds of metal and non-metallic ore, also can be dry grinding and wet grinding.If you are interested in our products or want to visit the nearby production site, you can click the button below to consult us.Welcome to our factory to test machine for free!
