TH10357C3 - Production process of self-compacting concrete mixed with rice husk ash from a thermal power plant - Google Patents

Abstract

The new request describes an improved process for producing self-compacting concrete mixed with rice husk ash from a thermal power plant. The process involves three mixing ratios of the concrete mixture using a mixer. The steps are 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 2 minutes. Step 2: After 2 minutes, add the total amount of rice husk ash and mix for 4 minutes. Step 3: After 6 minutes, add the total amount of cement and mix for 3 minutes. Step 4: After 9 minutes, add the total amount of crushed limestone and mix for 4 minutes. Step 5: After 13 minutes, add the total amount of water and mix for 2 minutes. Step 6: After 15 minutes, add the total amount of super-reducing admixture type G and mix for 5 minutes. The total mixing time is 20 minutes, resulting in self-compacting concrete mixed with rice husk ash.
