The paper reports experimental research regarding the mechanical characteristics of concrete reinforced with natural cellulosic fibers like jute, sisal, sugarcane, and coconut. Each type of natural fiber, with an average of 30 mm length, was mixed with a concrete matrix in varying proportions of 0.5% to 3% mass. The tensile and compressive strength of the developed concrete samples with cellulosic fiber reinforcement gradually increased with the increasing proportion of natural cellulosic fibers up to 2%. A further increase in fiber loading fraction results in deterioration of the mechanical properties. By using jute and sisal fiber reinforcement, about 11.6% to 20.2% improvement in tensile and compressive strength, respectively, was observed compared to plain concrete, just by adding 2% of fibers in the concrete mix. Bending strength increased for the natural fiber-based concrete with up to 1.5% fiber loading. However, a decrease in bending strength was observed beyond 1.5% loading due to cracks at fiber−concrete interface. The impact performance showed gradual improvement with natural fiber loading of up to 2%. The water absorption capacity of natural cellulosic fiber reinforced concrete decreased substantially; however, it increased with the loading percent of fibers. The natural fiber reinforced concrete can be commercially used for interior or exterior pavements and flooring slabs as a sustainable construction material for the future.

“…The availability and economy of SF makes it an easier option for the designer of concrete structure. SF improves the overall mechanical performance of concrete 12,19–26 and it lowers the resistance of concrete against the most common aggressive environments 12,20 . CF is a composite form of amorphous and graphitic carbon.…”

Durability and ductility of plain cement concrete (PC) can be upgraded by the simultaneous incorporation of fibers and supplementary cementitious materials. To this end, influence of different fibers such as steel fiber (SF), glass fiber (GF), carbon fiber (CF), and polypropylene fiber (PF) is studied on mechanical and durability properties of concrete with and without silica fume. Silica fume was used as 10% by mass replacement of ordinary Portland cement. Various mechanical and durability properties were studied such as compressive strength, split tensile strength, flexural strength, water absorption (WA), chloride penetration (CP), and acid attack resistance of concrete. The results of testing revealed that silica fume improved the efficiency of fibers in resisting the tensile and flexural loads. The composite effect of fiber and silica fume was more beneficial than the sum of the effects of their individual incorporation. Steel fiber‐reinforced concrete (SFRC) showed better mechanical performance at 28 days as compared to other FRCs but CFRC showed better performance at 180 days. PFRC and CFRC exhibited better durability performance than SFRC and GFRC. Silica fume helped in reducing the WA and CP of FRCs and improved their acid attack resistance.

“…Rashid and Balouch [12] confirmed by the experiment that the erosion products generated in the cement matrix and aggregate interface zone is formed after the samples are obviously swelled. Based on the experimental results, combined with the pressure of crystallization theory, it can be conjectured as follows: when the content of ettringite in cement matrix pore solution reaches its saturation concentration, ettringite crystal growth will occur in the narrow closed pores, and large produce crystallization pressure in this process is the main reason for the expansion of the cement matrix.…”

In order to study the whole process of corrosion expansion and cracking of protective coatings of reinforced concrete columns under the coupling condition of load and chloride corrosion environment, the transmission characteristics of chloride salts in loaded concrete columns and the deterioration mechanism of cracking and spalling of protective coatings caused by steel corrosion are studied. The transport characteristics of chloride salts in concrete under the coupling condition of load and erosion environment are studied by means of creep tester. The loadbearing levels of specimens are divided into four groups according to the design values of ultimate load: 0%, 20%, 40% and 60%. The transport of chloride ions in concrete in marine environment is simulated by dry-wet cycling method. The results show that the existence of compressive stress accelerates the chloride ion transport in concrete at the initial stage of loading, and the higher the stress level, the faster the chloride ion transport. With the increase of loading time, the stress hinders the transport process of chloride ion. In the same period, the transmission efficiency in concrete without stress is the highest. In the same period, the chloride ion concentration on the surface gradually decreases with the compressive stress level. The longer the time, the more obvious the downward trend. The peak chloride ion content has little change with the increase of the compressive stress level; at the same compressive stress level, the chloride ion diffusion coefficient is basically unchanged with the increase of the dry-wet cycle; in the same cycle, the chloride ion diffusion coefficient increases with the increase of the stress level, but does not show a linear relationship. Using large-scale finite element DIANA (High-end Nonlinear Finite Element Analysis Software), the whole process of rust expansion and cracking of protective layer of loaded concrete column is numerically analyzed.
