“…Fly ash or flue ash, also known as pulverized fuel ash in the United Kingdom, is a coal combustion product that is composed of particulates (fine particles of burned fuel) that are driven out of coal‐fired boilers together with the flue gases. The components of fly ash vary considerably; it includes substantial amounts of silicon dioxide (SiO 2 ), aluminum oxide (Al 2 O 3 ), and calcium oxide (CaO): main mineral compounds in coal‐bearing rock strata 86–88 . The minor constituents of fly ash depend upon the specific coal bed composition but may include one or more of the following elements or compounds found in the trace concentrations (up to hundreds ppm): arsenic, beryllium, boron, cadmium, chromium, hexavalent chromium, cobalt, lead, manganese, mercury, molybdenum, selenium, strontium, thallium, and vanadium, along with very small concentrations of dioxins and PAH compounds.…”

Advantages of fly ash in construction materials reduced water content for a given workability or improved workability at the same water content; improved more strengths and durability performances; and reduced shrinkage and porosity as a result of the lower water content.…”

The present study is focused on the compressive strength, water retention, and workability by varying the percentage of poly ethylene glycol 200 and liquid paraffin wax from 0% to 1% by weight of cement for self‐compacting concrete and compares it with conventional SCC. Percentages of 0.1%, 0.5%, and 1% (in proportion to the weight of cement) were adopted in the study. The comparison was done in a grade concrete and with cases such as indoor curing and water‐based curing. Slump‐flow test and V‐funnel tests were carried out on the fresh concrete to evaluate the workability of concrete. Concrete weight loss with time is evaluated to determine the water retention capacity. Compressive strength of cube specimens was conducted at the end of 7 and 28 days of curing. The durability of the concrete was assessed by immersing the concrete specimens in acids. The fresh properties were satisfied according to EFNARC specifications. Based on the weight loss percentage and satisfaction of compressive strength, the dosage of a self‐curing compound was determined. XRD analysis of the concrete was also performed on the concrete specimens.

Las cenizas de carbón son contaminantes ambientales, sin embargo, son utilizadas como aditivo en el cemento para la elaboración de hormigón, en obras de ingeniería civil. Se tuvo por objetivo evaluar información del uso de cenizas de carbón en la optimización de la resistencia del hormigón. Se realizó análisis de 61 artículos científicos de actualidad, identificando así informaciones referentes al uso de cenizas de carbón para mejorar la resistencia a la compresión del concreto. Se determinó que la resistencia promedio del hormigón habitual a los 28 días fue de 221 kg/cm2, con 2,5% de cenizas fue de 223 kg/cm2, con 5% fue de 231 kg/cm2, con 10% fue de 200 kg/cm2 y con el 15 % fue de 192 kg/cm2 respectivamente. Las cenizas de carbón usadas en proporciones menores al 10% en sustitución de cemento, mejora la resistencia del hormigón; en contraste, el uso superior al 10% puede disminuir la calidad del hormigón.

“…Ordinarily, concrete requires vibration and compaction to eliminate gas and voids in order to prevent poor resistance to load. (Dey et al, 2021). However, vibration and compaction are strenuous and cumbersome and can lead to undetected problems later if done inadequately.…”

This research compares the flexural resistance of self-compacting concrete (SCC) and High Strength Concrete (HSC) beams with embedded polyethylene terephthalate (PET) plastic bottle below the neutral axis using concrete grade of C70. Mix design for both SCC and HSC were performed in line with relevant specification. Experimental programme was achieved on both beam specimens. Workability, compressive and flexural strength tests were performed in the laboratory. The workability test revealed a more flowable concrete with the SCC mix than that of the HSC. The compressive strength for the SCC design mix yields a higher value (about 21.5% higher) than that of the HSC. The flexural resistance of each beam specimens (SCC beams and HSC beams) increases with increase in curing days of the beams but higher strength was achieved with SCC beams at 28 days curing. The stress-strain behavior is within the specified acceptable limit (0.002-0.0035) for concrete with grade less than or equal to C50/C60. It is concluded that the replacement of concrete with PET plastic bottles beneath the neutral axis will lead to reduction in volume of materials, reduction in environmental waste, price of removal of the garbage and eco-friendly environs.
