TH10358U - The process of producing self-compacting concrete mixed with bagasse ash from a thermal power plant. - Google Patents

Abstract

The new request describes an improved process for producing self-compacting concrete mixed with bagasse ash from a thermal power plant. The process involves three mixing ratios of the bagasse ash concrete mixture. The mixing is done using a mixer as follows: Step 1: Add all the river sand to the mixer. The mixer, with a cylindrical drum (100 cm diameter, 50 cm high), is operated at 80 revolutions per minute for 3 minutes. Step 2: After 3 minutes, add the total amount of bagasse ash to the mixing drum and continue mixing for 5 minutes. Step 3: After 8 minutes, add the total amount of cement and continue mixing for 3 minutes. Step 4: After 11 minutes, add the total amount of crushed limestone and continue mixing for 4 minutes. Step 5: After 15 minutes, add the total amount of water and continue mixing for 1 minute. Step 6: After 16 minutes, add the total amount of special water-reducing admixture type G and continue mixing for 5 minutes. The total mixing time is 21 minutes, resulting in self-compacting concrete. Self-stable compound mixed with sugarcane ash.

Claims (3)

New request updated. 1. The process for producing self-compacting concrete mixed with bagasse ash from a thermal power plant involves the following steps: a. Step 1: Place all the river sand into the mixer and operate the cylindrical mixer (100 cm diameter, 50 cm high) at 80 revolutions per minute for 3 minutes. b. Step 2: After 3 minutes, add the total amount of bagasse ash to the mixer and continue mixing for 5 minutes. c. Step 3: After 8 minutes, add the total amount of cement and continue mixing for 3 minutes. d. Step 4: After 11 minutes, add the total amount of crushed limestone and continue mixing for 4 minutes. e. Step 5: After 15 minutes, add the total amount of water and continue mixing for 1 minute. f. Step 6: After 16 minutes, add the total amount of super-reducing admixture type G and continue mixing for 5 minutes. The total mixing time is 21 minutes, resulting in self-compacting concrete mixed with bagasse ash. 2.
