Organosilicate Materials in Prestressed Reinforced-Concrete Structures
Abstract
The coatings used allow the application of the electrothermal prestressing process requiring a temp. of 300-400C, or the steam-curing of concrete, and provide a good, long-lasting anticorrosive protection. The compns. , in form of fine suspensions of silicates and oxides in toluene solns. of polyorganosiloxanes VN-30 (STU-30-2943-66) and C 2 (TU 17-69), viscosity 20-5 sec on the VZ-4 scale, were spread on the reinforcing elements in 3 layers, and dried 30-40 min at 10-20 degrees to produce a 0.3-1.0 mm thick coating. The elements, steel bars or strings, were used inside straight or curvilinear concrete products like blocks, slabs, or beams. A good strength, carrying capacity, and a lack of cracks were noted in the concrete products thus obtained.
