TH10358C3 - Production process of self-compacting concrete with bagasse ash from thermal power plants - Google Patents

Abstract

New requests, improvements The production process of self-compacting concrete with bagasse ash from the thermal power plant is carried out by using a mixture of 3 proportions of concrete with bagasse ash at the rate of one of three ingredients and mixed with a mixer according to Step 1 Put all the river sand in the mixer. Then walk the mixer with the tank Mix a cylindrical shape, diameter 100 cm., Height 50 cm. At speed of 80 rpm for 3 minutes. Step 2 At the end of the third minute, add all of the bagasse ash into the mixing tank and continue mixing for 5 minutes. 3rd, after the 8th minute, add the total amount of cement. Then mix for 3 minutes. Step 4 At the end of the 11th minute, add all the crushed limestone. Then mix for 4 minutes. Step 5 When the 15th minute, add all the water. Then continue to mix for 1 minute. Step 6 At the end of the 16th minute, add the total amount of special water reducing agent G type. Then continue to mix for 5 minutes, including 21 minutes of mixing time. Self-tightening mixed with bagasse ash
