“…It was noticed through the experimental results that splitting tensile strength of concrete decreases as the amount of CBA in the concrete mixincreases. It shows that the pozzolanic reaction did not initiateat the age of 28days [15][20] [21]. In the CBA concrete, the amount of ordinary cement is less as compared to the control mix (CM), therefore less strength was observed at the age of 28days.…”

The coal based thermal power plant in Malaysia produces annually around 1.7 million tons of coal bottom ash (CBA) as a discarded material which poses great environmental problems. Hence, the objective of this study is to utilize ground CBA as a supplementary cementing material in concrete. The oven dried original CBA was grinded for 20hours to achieve required fineness. The mixture of concrete was prepared with CBA proportion of 10, 20 and 30% by weight of cement. For the evaluation ofdensity, water absorption, compressive and tensile strength of concrete, 48 specimens were cast. The workability of fresh mix concrete was also evaluated, and it was found to be decreased as the quantity of CBA increased in the mixture. However, the compressive and splitting tensile strength of concrete was also reduced with the addition of ground CBA but with 10% replacement has attended the targeted compressive strength at the age of 28days.Besides that, it was also observed that the influence of CBA on concrete is obvious in density as well as in water absorption. The density of concrete gradually decreased due to addition of ground CBA, concrete containing 10% ground CBA was likely to be similar to that of control mix and the opposite performance was noticed in water absorption.Hence, experimental findings of this study indicated potentiality of ground CBA as supplementary cementing material in concrete construction which will reduces the environmental concern.

“…Al-Mansob et al [8] studied the effect of adding nano-alumina to bitumen and found that it has a significant hardening effect leading to both decreasing the penetration depth and increasing the softening point of the modified samples. Hussein et al [9] reported similar results for bitumen modified with ceramic waste nanoparticles consisting mainly of silica and alumina. Many studies have stated the effect of modifying bitumen with nano-polymer on the rheology and physical properties of the resultant composites [10][11][12].…”

Using nanotechnology in asphalt paving has increased markedly to improve the asphalt characteristics and increase the road life, especially with the significant increase in traffic volumes. The present contribution evaluates the effects of ore nanoparticles namely ilmenite and bentonite on the engineering properties and performance of asphalt binder. The high-resolution transmission electron microscopy (HRTEM) micrograph was used to characterize the investigated nanomaterials. The nanoparticles were blended with asphalt binder with different percentages (0-5% for ilmenite and 0-10% for bentonite by weight of asphalt binder) to determine the appropriate mixing ratio that sustained the desired characteristics. Different tests were conducted to examine the properties of modified asphalt binder among which penetration, softening point, rotational viscosity, penetration index (PI) and ductility. The results of our study revealed an increase in softening point and rotational viscosity and decrease in binder penetration. Moreover, blending of variable amounts of nanomaterials with the asphalt binders has improved their physical properties compared with macroparticles blended and unmodified binders as indicated by the penetration index and ductility test. The most significant improvement in the modified binders was obtained by blending of 5% for two types of nanoparticles. Finally, the rut depth was measured by wheel track test for the modified asphalt mixture, with ilmenite and bentonite, to validate the obtained results. The results show that the engineering performance of asphalt produced from bitumen binder modified with nanoparticles is much better than conventional asphalt and such binder-modified asphalt is strongly recommended for use on site.

“…Rejuvenators soften the aged bitumen causing the increase of penetration, ductility, phase angle and colloidal instability index, and decrease of viscosity and complex modulus [3,4,[12][13][14][15][16][17][18]. Meanwhile, recent investigations have shown a close relationship of microstructure with chemical composition and rheological properties of bitumen [19][20][21][22][23], assisting on understanding the rejuvenation mechanism. However, the rejuvenator's effect on the microstructure of aged bitumen is not well understood yet.…”

Observing the microstructure of bituminous binders with an environmental scanning electron microscope (ESEM) can contribute significantly to reveal the underlying rejuvenation mechanism. In this study, three rejuvenators were selected to regenerate the aged SBS modified binders at five dosages, and their rheology was evaluated using a dynamic shear rheometer. ESEM was employed to examine the microstructure of binders as well, and a series of microstructure parameters were quantified with image analysis. The results demonstrated that the chemical composition changes correspond to the evolution of microstructure morphological and rheological properties. Moreover, the rheological and microstructure characteristics were analyzed with Principal Component Analysis (PCA) and regression analysis. Based on PCA results, the microstructure of rejuvenated binders has shown a good correlation with stiffness after combining various principal components. According to regression analysis, the distance between adjacent fibrils exhibited a significant correlation with J nr3.2 and the complex modulus index. Overall, the results of this study strengthen the hypothesis that the ESEM microstructure is intimately correlated with chemical composition and rheological properties, rather than with irrelevant surface phenomena.
