Geopolymer concrete is a valuable and alternative type of concrete that is free of traditional cement. Generally, geopolymer concretes require a source material, which is rich in silicon and aluminum. Furthermore, fly ash-based geopolymer concretes have been proven to have superior fire resistance, primarily due to their ceramic properties, and are inherently environmentally-friendly given their zero-cement content. This paper presents the effects on initial evaporation on the performance of fly ash-based geopolymer pastes after exposure to elevated temperatures of 400 °C and 800 °C. The fly a

Concrete is one of the most widely used materials within the construction industry due to its versatility, durability, superior mechanical properties and excellent resistance to fire. In addition to this, the rapid growth in population and urbanisation has accelerated the demand for high strength concretes. However, high strength concretes suffer a condition called spalling when exposed to elevated temperature levels which is associated with the breaking away or exploding of concrete layers due to the internal stresses. Additionally, concrete is a material having a very high carbon footprint m

This chapter focuses on Richard Durham's career as a scriptwriter for television. Durham had been wanting to write for television since the early 1950s. The year 1969 brought the promise of creating a unique TV series, to be called More from My Life. The show, to air on noncommercial station WTTW-TV, would be a soap opera about black life in Chicago. In the past, Durham's TV scriptwriting desires had been dashed while he legally sparred with NBC. But after that fight ended, Durham served as a ghostwriter for science fiction shows like One Step Beyond, Climax, and The Outer Limits, as well as o

This chapter enters the realm of medieval Christian mystical women, who were purported to have levitated, moved through the air, or flown, and then explores their reception by a suspicious, male-dominated Church. To understand the intensely devotional beliefs of these women, and the social status of religious women, requires exploring the different perceptions of female and male mystics and their different mystical experiences. A major problem with female Christian mystics was that women were generally considered to be more susceptible to demonic possession than men, and peoples possessed by t

Dragonflies are conspicuous insects. Many are large; they fly strongly; most are brightly coloured. As a result, they have been collected extensively. Their larvae are less familiar. 'Mud-eyes', as some are called, are drab, and almost all live in fresh waters, out of sight. They are, perhaps, best known as bait for freshwater fish. The dragonflies constitute a very distinct order of insects, the Odonata. In Australia, two suborders are represented: damselflies (Zygoptera), generally very slender insects, the fore- and hindwings similar in shape and venation and commonly held closed abov

In the early 1930s, during his first years of exile and 20 years before the publication of his seminal workTo the Actor,Michael Chekhov made his first incursion into the challenging task of writing about an actor’s experience and his vision of the craft. This important, though largely forgotten, work (the so-called ‘Paris Manuscript’) was handwritten in German and in it we find Chekhov laying the groundwork for the canon of exercises and practices that, nearly a century later, has widely become known as the Michael Chekhov Technique.

Abstract Every literary household in nineteenth-century Britain had a commonplace book, scrapbook, or album. Coleridge called his collection “Fly-Catchers”, while George Eliot referred to one of her commonplace books as a “Quarry,” and Michael Faraday kept quotations in his “Philosophical Miscellany.” Nevertheless, the nineteenth-century commonplace book, along with associated traditions like the scrapbook and album, remain under-studied.

Cricket song is a sound of the Australian bush. Even in cities, the rasping calls signify Australia’s remarkable cricket biodiversity. Crickets are notable for a variety of reasons. When their population booms, some of these species become agricultural pests and destroy crop pastures. Some introduced species are of biosecurity concern. Other crickets are important food sources for native birds, reptiles and mammals, as well as domestic pets. Soon you might even put them in your cake or stir-fry, as there is a rapidly growing industry for cricket products for human consumption. Featuring

The disease is difficult to diagnose and hence frequently neglected.

This paper presents a review on fly ash as prime materials used for geopolymer. Due to its advantages of abundant resources, less in cost, great workability and high physical properties, fly ash leads to achieving high mechanical properties. Fly ash is considered as one of the largest generated industrial solid wastes or so-called industrial by-products, around the world particularly in China, India, and USA. The characteristics of fly ash allow it to be a geotechnical material to produce geopolymer cement or concrete as an alternative of ordinary Portland cement. Many efforts are made in this

Cracks are a common phenomenon in large-volume concrete and are an important issue of concern in the engineering field.

Tall and trim, the slender neckwear accentuating the span of his military frame, and exceedingly vain of his good looks, he did not lend himself to diminutives of any sort; on the contrary, he was more martinet than Marty

Abstract. No-fine concrete (also called as pervious concrete or porous concrete) is a lightweight concrete made up of primary binder and coarse aggregates with little or no sand. Due to the reduced amount or absence of fines, it produces large number of voids which improves permeability to greater extent. Hence this type of concrete can be used in pavements and in parking lots. The literature review is carried out to study the physical and mechanical properties of no-fine concrete with additives. Various reports were collected and studied about variation in physical and mechanical properties o

ABSTRACT Cementing is an integral operation in any oil and gas well. Although conventional cement has been used for many years, it suffers from two significant problems. These include significant numbers of failures especially at extreme conditions, and environmental damage due to high emissions generated during cement production. This research overcomes these two problems by developing a novel environmentally friendly and high durability epoxy based cement reinforced with low cost fly ash. More than 100 different samples were prepared for the novel cement for evaluation. Different formulation

However, coal combustion generates a significant number of by-products, majority being the coal fly ash (CFA).

Therefore, this research aims to improve CFA's suitability for the application of value-added products through a technique called “washing cycles” which wash the CFA multiple times using dis

Abstract. The production of concrete involves the use of huge quantity of cement which is the main binder material. However, cement production involves the use of high amount of embodied energy and reduce of embodied CO2 emission. Hence one of the alternatives is the use of concrete with zero cement called geopolymer. However, the main shortcoming of geopolymer is its higher brittleness and low modulus of elasticity compared to conventional cement concrete. This led to the addition of fibres to geopolymer.
