Type I and III cements can cause higher concrete shrinkage than type II cement because of their higher water demands. , petroleum-impacted soil), the significance of vapor intrusion into the building depends on the source vapor concentration, the relative position of the vapor source and building, and the rate of O2 transport from the atmosphere to the soil gas beneath the building. The slabs will not have grade beams but will be a “uniform thickness” throughout the slab of about 10 inches. living area below the parking slab including a bathroom and small kitchen. For most pavements, the governing design consideration will be the flexural tensile stress induced in the concrete by wheel or post loads. Thanks for reading, Jason.
