Traditional materials, highly adaptable for custom shapes but limited in reusability.
Engineers and site superintendents can access complex pressure charts and bracing diagrams instantly on tablets or smartphones directly at the construction site.
Calculating the exact pressure exerted by fresh, wet concrete on the form faces is arguably the most vital step in formwork design. Fresh concrete behaves like a fluid until it begins to set, exerting hydrostatic pressure. ACI SP-4 provides empirical formulas and tables for calculating these lateral pressures, factoring in variables such as: Rate of concrete placement Concrete temperature Concrete weight and consistency The use of admixtures or pozzolans 3.
