Cementitious matrix
-
In Viet Nam, natural fibre-reinforced cementitious matrix (N-FRCM) can be a material solution in some situations and works if research is oriented. This paper presents a state-of-the-art review of the physical and mechanical properties of N-FRCM composite. By inheriting previous review studies in the literature, this paper updates more on the experimental studies on the N-FRCM composite in the last decade.

This is due to the reduction of calcium hydroxide and the increase of secondary CSH in the cement matrix from the pozzolanic reaction of a mineral admixture. The result of the study with modern experiment methods confirmed the improvement of strength and durability for hardened cement using mineral admixture, thereby ensuring the good applicability of the additional admixtures used in concrete of marine structures.

This paper presents the experimental characterization and analytical modeling for fire performance of carbon TRC under the thermomechanical regime at constant tensile force. The carbon TRC is manufactured from the cementitious matrix with good thermal properties (refractory matrix) and the reinforcement of carbon textiles.

The viscoelastic model results from a homogenization procedure in which the Mori-Tanaka scheme is applied in the Laplace-Carson space for estimating the effective linear viscoelastic bulk and shear moduli of the material. A concrete material made of a linear viscoelastic matrix described by a generalized Maxwell model and containing distributed spherical elastic inclusions and pores is adopted as a simplified representation of the material under consideration.

The stress jumps in reinforcement textile after each crack was also observed and analyzed. In comparison with the experiment, a good agreement between both results was found for all cases of this study. A parametric study could show the effect of the length and position of the measurement zone on the stress-strain curve of TRC’s mechanical behavior.

The study of the mechanical behavior of sand concrete mixed with polypropylene (PP) fibers shows that with the incorporation of (PP) fibers into the cementitious matrix, there is some improvement in the ductile behavior of the composite. In our study we tested the composite with different dosages of polypropylene (0.05%, 0.1%, 0.3% and 0.5%).

The high temperatures of fires affect the physical and chemical properties of the concrete and thus influence its mechanical properties. This paper presents the results of an experimental investigation on the compressive strength at high temperatures of high-strength fibre concretes. The influence of the high temperatures on the physical and chemical changes of the concrete was also analysed by Thermo Gravimetric Analysis/Differential Thermal Analysis (TGA/DTA), X-Ray Diffraction (XRD) and Scanning Electron Microscopy with Energy Dispersive Spectrometry (SEM/EDS).
