“…In addition, densification of the transfer matrix of mortars and good resistance to carbonation were exhibited. Similar results were presented in [12], where it is stated that the pozzolanic activity of PP is slow in the early age and develops with time, resulting in a decrease of absorbability and porosity and an increase in strength.…”

This study compares the performance of perlite with that of conventional additives in blended cements. The results of the application of Perlite Powder (PP) as a component of blended cements in two different proportions (30% and 50%) are presented and compared with standard additives of fly ash (FA) and Ground Granulated Blast Furnace Slag (GGBFS). Moreover, perlite is tested as a component of ternary cement (70% cement, 15% P and 15% FA and GGBFS alternatively). Blended cements are tested in terms of flexural strength, compressive strength, bulk density, water absorption, and frost resistance. The results show that although perlite blended cements achieve lower strengths and higher absorptivity compared to conventional additives, they have significant potential for freezing and thawing durability, especially in ternary combination with GGBFS. For practical applications, the intrinsic values of the parameters of the individual binders with perlite (e.g. flexural strength of 4.1–6.2MPa or compressive strength of 18.8–38.5MPa) are sufficient for many practical applications. Perlite, when suitably combined with other pozzolanic materials, can be a suitable component of blended binders.

“…Owing to high melting point, silica (sand) is widely used as core ingredient in manufacturing many engineering related equipment as well as sand casting [6]. Moreover, the correct amount of silica sand improved the strength of cement mixture which make silica as a useful binding component in concrete production [7]. In addition, some publication in nanomedicine describes the use of silica nanomaterial in emerging therapy where silica nanospheres reported being used as Magnetic Resonance Imaging (MRI) contrast agent [8,9].…”

Nano scale fibers of SiO2 and TiO2 with various compositions of viscosity and parameter have been prepared by electrospinning the precursor of tetraethyl orthosilicate (TEOS) and titanium (IV) isopropoxide (TiP). Different concentrations of polymer precursor polyvinylpyrrolidone (PVP) and applied voltages were studied. Distance tip to collector of 15 cm and flow rate of 0.003 mL/h were fixed for entire electrospinning process. The morphology of nanofibers was evaluated versus different solution concentrations as well as different applied voltages. Concentration focused in this study included 5 %wt, 10 %wt and 15 %wt of PVP along with 15 kV – 17.5 kV of voltages applied. The as-spun nanofibers were characterized by SEM. Results showed that the average fiber diameter decreases with decreasing of polyvinylpyrrolidone (PVP) solution concentration.

“…SP also controlled the temperature of the solutions used during the test. Esfandiari and Loghmani [19] examined the impact of perlite powder and SP on the compressive strength and microstructural properties of SCC with a lime-cement binder. For this purpose, SP and perlite powder were employed at 0%, 5%, 10% 15% and 20%.…”

This study intends to assess the influence of steel fibres (SF) and polypropylene fibres (PPF) on the hardened and fresh state properties of high-strength concrete (HSC). For this purpose, 99 concrete mixes were designed and applied. SF and PPF were used at six-volume replacement contents of 0%, 0.1%, 0.2%, 0.3%, 0.4% and 0.5%. Moreover, nano-silica (NS) was used at three contents, 0%, 1% and 2%, and silica fume powder (SP) was also used at three weight ratios (0%, 5% and 10%). The slump, compressive and tensile strength, elasticity modulus, water absorption and the electric resistivity of concrete specimens were examined. The results showed that using 1% NS and 10% SP together with 0.5% PPF improved the compressive strength of HSC by about 123%; however, the effect of SF on tensile strength is more significant and adding 0.5% SF with both 2% NS and 10% SP increased the tensile strength by 104%. Moreover, increasing the SF content reduces the electric resistivity while using PPF improves this property especially when 1% NS was employed, and it was enhanced by about 68% when 0.5% SF and 1% NS were utilized with 10% SP.
