“…Nittaya, et al [1] and Ozyildirim, et al [2] examined the effect of adding NS on the density of concrete. Furthermore, Forood Torabian Isfahani et al [3], M. Nili, et al [4] Valquiria S., et al [5], and Zhang, M. [6] studied the effects of the use of nano-silica on compressive strength of concrete. Lin DF, et al [7], and Björnström J [8] confirmed that the SiO2 nanoparticles increased concrete strengths and enhanced its resistance to water absorption (WA).…”

The demand for High Performance Concrete (HPC) is steadily increasing with massive developments. Conventionally, it is possible to use industrial products such as silica fume (SF), fly ash, as supplementary cementitious materials (SCM), to enhance the attributes of HPC. In recent years, nano-silica (NS) is used as an additive in added mainly to fill up the deviation arises with the addition of SF for HPC. This study aims to optimize the proportion of NS (produced in Vietnam) in the mixture used for fabricating 70 MPa high-performance concrete. SiO2 powder with particle size from 10 to 15 nm were used for mixing. A series of compressive strength test of HPC with nano-SiO2 varied from 0 to 2.8 percent of total of all binders (0%, 1.2%, 2%, 2.8%), and the fixed percentage of silica fume at 8% were proposed. Results show compressive strength increases with the increase of nano-SiO2, but this increase stops after reaching 2%. And at day 28 of the curing period, only concrete mixture containing of 8% silica fume and 2% nano-SiO2, had the highest compressive strength.

“…In concrete technology, several nanoparticles have been widely used by many researchers to improve the quality of cement materials, by modifying microstructure, mechanical properties and durability of concrete or mortar [2 3]. The results obtained there is a linear and significant relationship between the strength of durable concrete and nanoparticles [4]. Nanoparticles increase the aggregate contact zone structure, namely the interface transition zone between aggregates and mortar, resulting in better bonding between aggregates and cement paste [5 6].…”

The development of nanotechnology continues to grow. The use of nanocement in concrete is expected to reduce the number of pores and improve hydration in concrete and provide more strength to the concrete. The use of natural fibers, in this case, coconut fiber can prevent cracks in concrete and make fiber concrete more ductile than ordinary concrete. The effect of using nanocement on coconut fiber concrete on the strength of the concrete to be studied. Methodology to complete the research objectives, use nanocement used in concrete, which has added coconut fiber. Tests reviewed the value of slump and specific gravity. Then, testing the compressive strength at 7, 24, 28 days. The results obtained were an increase of 48.19% in the strength of concrete. Further research needs to review on mixing nanocement with other natural fibers.

“…Nano-materials, as a novel modified additive, have different physical and chemical properties due to their nanometer-level dimension. Study on the mechanical performance of concrete incorporated with nanoparticles as modified additives has been highlighted in previous literatures (Zhang, Wang, and Zhang 2011;Li et al 2015;Silva et al 2016;Ma et al 2016). Currently, increasing attention has been devoted into the durability of concrete with nano-particles.…”

Alkali-silica reaction (ASR) is a serious durability problem, resulting in significant maintenance and reconstruction cost of concrete infrastructure all over the world, so more and more attention has been attracted to it. This paper tends to discuss whether nano-SiO 2 and nano-Fe 2 O 3 can mitigate the concrete deterioration caused by ASR. The test results show that the concretes with nano-particles have lower expansion and higher sonic velocity. Therefore, it is an available method for concrete to mix with nano-particles to mitigate ASR and the optimum content of nano-SiO 2 and nano-Fe 2 O 3 in concrete is 2.0% and 1.0%, respectively. The mitigating mechanism is revealed through the effect of mixing water on the porosity.
