“…These data slightly differ from those obtained by XRF (Table 1), which were between 37.5% and 39.5%, although it should be noted that these methods are very different. Calcination in a microwave oven for 30 minutes at temperatures of 600°C and 700°C resulted in ashes with the highest amorphous silica content (17.5% and 16.6% respectively).…”

“…Ashes such as SCBA, which contain elevated levels of organic carbon-based material, show strong potential for microwave oven calcining, since carbon materials have high microwave absorption [30][31][32][33][34]. However, few studies have reported the use of a microwave oven in the calcination of agroindustrial ashes [35][36][37][38][39][40]. The most detailed study found in the literature [35] analysed the calcination of rice husk ash in a microwave oven at temperatures above 800ºC for 45 minutes, which resulted in ash with high levels of cristobalite and quartz.…”

Self-compacted concrete (SCC) is cast in the formwork without compaction and it fulfills the formwork due to its own weight. SCC is considered to have many advantages in comparison with conventional concrete like improved construction quality, faster construction activity, reduced cost etc. SCC is produced with the same ingredients of normal concrete. However, cementitious materials are also adopted to replace the cement content in SCC in order to use waste materials from industries and agricultural products. To further enhance the performance of SCC, different types of fibers are tried in order to produce fiber reinforced SCC. The fibers in the concrete bridge the cracks and diffuse the crack propagation which improves mechanical properties. In developed countries SCC has reasonable acceptance in construction industry but in developing countries like Pakistan has not gained acceptance. This paper is focused on undertaking a review of SCC with cement replacement and fiber reinforcement materials. The main objective of this paper is to compile the literature in order to understand the various properties of SCC in fresh and hardened state when these cement replacement materials and fibers are used.

“…HSC with high strength and durability shows lower performance than normal strength concretes under high temperature effect 1,2 . Many previous studies have indicated that high temperature negatively affects the mechanical properties of HSC 2–5 and other concretes 6–18 . Schneider 19 demonstrated that the type of aggregate, heating and cooling down process and moisture content are parameters that influence most the mechanical properties of the concrete.…”

This paper presents the results of an experimental research on the assessment of the residual mechanical properties of high strength concretes (HSCs) made with pyrophyllite aggregate (PA) after high temperature. In the study, HSC mixtures with varying PA ratios (0, 25, 50, 75, and 100%) were subjected to elevated temperature (150, 300, 450, 600, and 750°C) and then cooled in two different cooling regimes (air and water‐cooling). The properties examined included compressive strength, weight loss, effects of cooling regime, and microstructure of HSC. The results of the study show that the increase in the PA ratios leads to a decrease in the compressive strength values. The results showed that weight loss of the specimens decreased with increasing PA ratios. It was found that the compressive strength values of HSC with PA cooled in air‐cooling are higher than that cooled in water. When the compressive strength loss and the weight loss values are taken into consideration according to the control samples, the group with the highest resistance to high temperature (750°C) effect was 100% PA group. Also, the internal structures of the samples exposed to high temperature were examined using scanning electron microscope and visual observations.
