From the study found that the foam bubbles production cleaners that make concrete lighter mass is the maximum pressure, including A secondary liquid is B, D, and C, all cleaners.
The study found that the solution produces foam makes lightweight concrete compressive strength of up include reagent A, followed by B, D and C, all reagents.
The study found that the liquid producing foam making lightweight concrete compressive strength were A maximum fluid respectively, and B D C by all agents
