🏗️ ACI 347R Lateral Pressure Pmax (PSF), Pour Rate (Ft/Hr) & Tie Spacing Sizing

Concrete Wall Formwork Lateral Pressure Calculator

Calculate maximum lateral concrete pressure on vertical wall and column formwork under ACI 347R: calculate Pmax (PSF based on liquid head, rate of placement R ft/hour, fresh concrete mix temperature °F, and chemical retarders), form tie load tension capacities, and structural formwork margins.
