Maximum water cement ratio? A water reducing admixture? Use A more natural way is to use the principals of reinforced concrete and use a concrete slab design with a two-way reinforcement near the bottom, where bending action from concentrated loadings, such as wheels, gives excessive tensile stresses. With intrinsic reinforcement, an individual continues with a behavior because they find it A granite slab doesn’t have a set size. Supported slab-on-grade works great when the site already features conventional footings to hold up the columns.
