Behaviour of ambient cured prestressed and non-prestressed geopolymer concrete beams
Case Studies in Construction Materials, 2022 One of the sustainable alternatives to Portland cement is geopolymer concrete consisting of industrial waste. Practical application of geopolymer concrete is restricted as it requires the use of high temperature to develop compressive strength.

CFRP strengthened continuous concrete beams [PDF]
Structures <html_ent glyph="@amp;" ascii="&"/> Buildings, 2003 This paper reports the testing of five reinforced concrete continuous beams strengthened in flexure with externally bonded carbon-fibre-reinforced polymer (CFRP) laminates. All beams had the same geometrical dimensions and internal steel reinforcement. The main parameters studied were the position and form of the CFRP laminates.

Design And Tests Of Prestressed Concrete Beams [PDF]
Fire Safety Science, 1997 A prestressed TT beam had been designed considering the ultimate limit state of bending, and considering a temperature distribution given by a graph which was valid for a section with a similar shape. When tested in a furnace, it proved to have a fire resistance of only 79 minutes instead of the 2 hours foreseen by the calculation. An investigation was
