The hydration rate of wet concrete, which is the rate at which the concrete sets, depends upon many factors. On a hot sunny day with little or no humidity, concrete may set at a very fast rate, leading to shrinkage and a weaker structure. Test the concrete from the truck and ask the driver to add more water until you like the consistency.
Corrosion is not a concern when steel is enclosed by building finishes, coated with a contact-type fireproofing or in contact with concrete. In these cases, the steel does not need to be primed or painted. This covered condition applies to the majority of steel building applications, which leaves only a few special conditions where steel needs ...

Mar 30, 2012 · How much steel fiber is added to a concrete mix depends on the objectives: cost savings, increased joint spacing, or structural improvement. Steel fiber dosages can be as light as 8 pounds to as much as 200 pounds per cubic yard. Increasing the percentage of fibers in a mix allows specifiers to increase the distance between joints.
Mar 13, 2005 · Although on larger projects iron-workers will place the reinforcing steel, most contractors place some reinforcement. Getting it in the right place and keeping it there during concrete placement is critical to the structure's performance. Reinforcement should be placed as shown on the placing drawings.
The Benefits of Stainless Steel Stainless steel is a corrosion-resistant alloy of iron, chromium and, in some cases, nickel and other metals. Completely and infinitely recyclable, stainless steel is the “green material” par excellence. In fact, within the construction sector, its actual recovery rate is close to 100%.
