SYSTEM, METHOD AND APPARATUS FOR ENTRAINING AIR IN CONCRETE |
摘要 |
A method of preparing a concrete composition includes utilizing a controller to control a process including circulating process water in a process water supply loop for a predetermined period while monitoring and controlling the temperature and flow rate of the process water, circulating aqueous-based air entrainment solution in an aqueous-based air entrainment solution supply loop for the predetermined period and controlling the flow rate of the aqueous-based air entrainment solution and after the predetermined period of time in which the flow of process water and aqueous-based air entrainment solution have stabilized, simultaneously actuating valves to divert and mix the process water, the aqueous- based air entrainment solution and compressed air to produce an air-entrained foam and mixing the foam with a concrete composition. |
