Concrete-Filled FRP Tubes: Manufacture and Testing of New

May 30,  · Abstract. This paper reports on the development and testing of three new concrete-filled fiber-reinforced polymer (FRP) tube (CFFT) systems. These CFFT systems were designed to enhance the effectiveness of square and rectangular FRP tubes in confining concrete. In the design of the rectangular CFFTs two different enhancement techniques were considered; namely, corner strengthening and provision of an internal FRP

Fiberglass Pools vs. Concrete Pools vs. Vinyl Liner Pools

Vinyl liner pools need a new liner every 5–9 years, and often a buyer will require the current owners to replace that themselves. Vinyl liner and aboveground pools don't look great, either, and can detract value. By contrast, a fiberglass pool adds to the value of your home. Low-maintenance beauty and durability are a win-win for both parties.
