Finally, some contractors in cold climates began installing a continuous horizontal layer of rigid foam insulation under their concrete …
More DetailsConcrete is commonly specified by compressive strength f''(c ). It is typical to specify a minimum design strength of 4000 psi at 28 days with a maximum water-cementitious ratio (w/c) of 0.45, in most areas of the country. Since South Dakota experiences freeze-
More Detailsration can also be used to interlock concrete and steel. Composite deck finishes are either galvanized (zinc coated) or phosphatized/painted. Phosphatized/painted deck has a bare (phosphatized) top surface which is the side to be in contact with the concrete. This bare top surface can be expected to develop rust before concrete is placed.

More Details· The first step to recycling old concrete is to use industrial crushing equipment in order to break up the original structure. Next, the broken up concrete is run through a secondary impactor. After being crushed to an even smaller size, the crushed concrete is then screened so that dirt and other foreign objects can be removed.
More Details· When, if ever, should you consider installing a continuous layer of rigid foam under a concrete slab? The answer to this question depends on at least four factors: (1) your climate zone, (2) the height of the slab with respect to grade, (3) whether the room above the slab is used for living space; and (4) whether the slab has hydronic heat.
More DetailsWhen waiting for concrete to dry, keep these timeframes in mind: 24 to 48 hours - after inital set, forms can be removed and people can walk on the surface. 7 days - after partial curing, traffic from vehicles and equipment is okay. 28 days - at this point, the concrete should be fully cured.
More Details· The desired concrete crushing failures shown in Figs. 1.24 and 1.25 can only be achieved if IC, CDC and PE debonding can be prevented from occurring before the design load to cause concrete crushing. However, this may not always be possible; in which case, it may be necessary to design for either IC or CDC debonding to occur at the design load so that concrete crushing will not …
