“…To overcome these drawbacks, inorganic matrix systems have been introduced as a replacement for the organic systems [13][14][15][16][17][18][19][20]. The use of the fiber textiles, in conjunction with the development of new materials for the fiber, is able to ensure an adequate bond between textile and matrix.…”

“…Yang et al [22] indicated that a small corner radius can significantly reduce the ultimate strength of the FRP laminate due to the stress concentration around the corner area. Trapko [20] investigated the efficiency of Polypara-phenylenebenzo-bisthiazole (PBO) fiber bidirectional wrapped mesh, with a quantity of fiber in the direction of the wrap four times than those in the direction of the weft, embedded in an inorganic matrix in order to confine concrete cylinders. De Caso y Basolo et al [18] studied different type of grouts as inorganic matrices along different types of fiber (unidirectional and bidirectional meshes of low-density and high-density glass fiber sheets).…”

Simplified analytical models for compressed concrete columns confined by FRP and FRCM system

In order to consider the response of concrete columns confined by FRP and FRCM system, proper models have to be formulated. In this context the present paper shows a generalized criterion for the determination of the increase in strength, in ductility and in dissipated energy for varying corner radius ratio of the cross section and fiber volumetric ratio. The procedure is based on the best fitting of several experimental data and unlike the usual empirical approaches available in the literature, the proposed technique relates the confinement effectiveness to a single parameter representative of the relative stiffness between the original concrete core and the reinforcement system. Furthermore, the proposed analytical models overcomes the limit of many empirical or semi-empirical models given in the literature that are applicable only to specific cases. A comparison with same available models confirm the reliability of the proposed procedure.

“…13 Current studies usually focus on either fibre-reinforced resinous matrix confined concrete columns or fireproof grout only, 14,15 but it is rare to use grout as the fibre matrix and connect the fibres and concrete with grout instead of resin. Thus, as an economical and fireproof material similar to the fibre matrix, 16,17 the use of grout instead of resin may be a simple and convenient means of improving the fire safety of confined concrete columns. Moreover, it can improve the ductility of confined concrete columns.…”

Poor fire resistance of fibre-reinforced polymer (FRP) restricts its further application in construction structures. In this paper, a novel fibre-reinforced cementitious matrix confined concrete column (FRCMCC) using fireproof grout as the fibre matrix was developed, and experiments were conducted to establish its performance and analyse the mechanical properties under axial compression. The test results show that its failure mode was more moderate compared to the traditional fibre-reinforced resinous matrix confined concrete column (FRRMCC), and the concrete columns confined with multi-layer fibres and end reinforcement could provide both good strength and ductility.

Specific chemical environments step out in the industry objects. Portland cement composites (concrete and mortar) were impregnated by using the special polymerized sulfur and technical soot as a filler (polymer sulfur composite). Sulfur and technical soot was applied as the industrial waste. Portland cement composites were made of the same aggregate, cement and water. The process of special polymer sulfur composite applied as the industrial waste is a thermal treatment process in the temperature of about 150-155 • C. The result of such treatment is special polymer sulfur composite in a liquid state. This paper presents the plastic constants and coefficients of thermal expansion of special polymer sulfur composites, with isotropic porous matrix, reinforced by disoriented ellipsoidal inclusions with orthotropic symmetry of the thermoplastic properties. The investigations are based on the stochastic differential equations of solid mechanics. A model and algorithm for calculating the effective characteristics of special polymer sulfur composites are suggested. The effective thermoplastic characteristics of special polymer sulfur composites, with disoriented ellipsoidal inclusions, are calculated in two stages: First, the properties of materials with oriented inclusions are determined, and then effective constants of a composite with disoriented inclusions are determined on the basis of the Voigt or Rice scheme. A brief summary of new products related to special polymer sulfur composites is given as follows: Impregnation, repair, overlays and precast polymer concrete will be presented. Special polymer sulfur as polymer coating impregnation, which has received little attention in recent years, currently has some very interesting applications.
