Alternate Building Materials Used in The Construction Industry

PC: theconstructor.org Alternate building materials are those which can be used economically by replacing the conventional building materials. Alternate building materials are made from waste products and thus they minimize environmental pollution. These alternate building materials can be used when they meet their respective specifications in the code of practice. Here are some novel construction materials and technology, with some briefly discussed: Aluminum Bitumen Materials Soil Conditioning Agents Tempered Glass Crumb Rubber Fiber Reinforced Polymer Glass Fiber Reinforced Plastics Bamboo reinforced plastics Ferro-cement Polyester Fibers ALUMINIUM sound-proof-aluminium-construction. PC: theconstructor.org More than 3000 commercialized applications. 35 percent aluminum produced is used in construction. Non-Corrosive. High durability and low maintenance. Can be alloyed. Ductile and malleable. Aesthetically attractive. Applications of Aluminum In...

Personality of The Week: Mr Ebo Quansah

Mr Ebo Quansah, Personality of The Week To  begin this month's Alumni Awareness session of the Personality Dialogue a former Teaching Assistant of the Department.

When the Lass I was Loving for Years Finally said Yes!: Episode 3

Episode 3 (Final): The D-Day Presently, both of our families were aware of our relationship. Akos was an only daughter, but not an only child, as she had a brother who was as fine as herself. It seemed to me that fineness ran throughout the family--from dad to mum to children. Akos was much like her mother, and her brother, Yaw, who was older than her, took the form of her father. I had met Yaw a couple of times on campus, when he used to come visit her dear sister. As time elapsed, I became a family friend to the Sarpongs. The D-day finally arrived. I went to Akos’ residence to pick her up for our much anticipated Friday night time-out. Luckily for us it was a holiday, so we both had time to rest from the week’s busi-ness. Of course, holidays bring some delight to those whose weekly schedules are largely occupied by work or school--and without a doubt, the greater joy goes to our dear students. Operation Neptune  arrived at her residence in a black Chevrolet Cruze...

When the Lass I was Loving for Years Finally Said Yes!: Episode 2

Episode 2: Scaling Up Our Friendship It was on one occasion of a date at Chilly Bowl, in the first semester of my final year, that I asked if she would be my girlfriend. (The bond had become too strong to break, and I didn’t want to graduate 4-0, hahaha ). She was stunned at first, and I got stunned too. She asked me to give her some time to think it over. I gladly consented, but deep within I feared I would be bounced . As I patiently waited for my dear Akos to give me a favourable response, I would often get beset with mixed feelings. I told my roommate I had proposed to Akos. Kwao: Boy you for pray say she go accept oo. Me: What else chale. My love for her has transcended the skies. Kwao: You den your vibes. Me: No be small punch line oo chale. But e go source. After about two weeks since we last met at Chilly Bowl, I picked up my phone one Saturday evening to answer a call, and surprisingly, it was Akos. I hadn’t heard from after our recent date. We exchange...

When The Lass I Was Loving for Years Finally Said Yes!: Episode 1

PC: Pinterest Episode 1: Getting Acquainted I sent her a text on WhatsApp, ‘‘Bae, we’ve got a date on Friday night at Sparkles .’’ I’m sure she would have thought it would be one of our usual rendezvous , where we would chit-chat all night long talking about ourselves, among other matters, and getting a bit amorous sometimes, hahaha . But behind the scenes, something spectacular was boiling . She sent a reply, ‘’OK boo. I’m anticipating and will prepare in advance. Love youuu.’’ ‘’Love you bunch,’’ I responded. I was also preparing ahead for this big day where I would pop the question to the love of my life. I couldn’t wait for that grand day--the D-day--to declare myself to my better half. You could imagine all the sponging  and grooming that would go in on my side; and on the other side too, well, I couldn’t really guess. ’’Anticipate’’ was the only option. Akos was a lovely and comely young woman. She was beautiful in every sense of the word. She was tall (I was tal...

Researchers Discover New Useful Nanostructure for Composite Material

Biwu Ma, professor of chemistry and biochemistry  Florida State University researchers have discovered a novel structure for organic-inorganic hybrid materials that shows potential for more efficient technologies. Professor of Chemistry and Biochemistry, Biwu Ma, and his team have published a new study in the journal Science Advances, that explains how they created a hollow nanostructure for metal halide perovskites that would allow the material to emit a highly efficient blue light. Metal halide perovskites are materials that have shown great potential for photon-related technologies such as light-emitting diodes and lasers, but scientists have still been working to make them more efficient and effective. "The fabrication of new-generation color displays and solid-state lighting requires luminescent materials and devices of the three primary colors: red, green and blue (RGB)," Ma said. "Although multiple ways of color tuning have been demonstrated for perov...

Introduction to Glass Science and Technology

Technological History The presence of glasses in our everyday environment is so common that  we rarely notice their existence. Our current casual attitude toward the family of materials known as glasses has not always existed. Early Egyptians considered glasses as precious materials, as evidenced by the glass beads found in the tombs and golden death masks of ancient Pharaohs. The cave-dwellers of even earlier times relied on chipped pieces of obsidian , a natural volcanic glass, for tools and weapons, i. e., scrapers, knives, axes, and heads for spears and arrows. Humans have been producing glasses by melting of raw materials for thousands of years. Egyptian glasses date from at least 7000 B.C. Ancient Egyptian glass beads. PC: Science News How did the first production of artificial glasses occur? One scenario suggests the combination of sea salt (NaCl) and perhaps bones (CaO) present in the embers of a fire built on the sands (SiO 2 ) at the edge of a saltwat...

The Quality of Locally-manufactured Cornmill Grinding Plates

Corn mill A KNUST research has revealed people who consume corn-related foods risk contracting all kinds of cancers According to the research, the locally manufactured machine used to grind the corn into dough food wears off faster into the dry maize, thus contaminating it. A study by two lead researchers at the Kwame Nkrumah University of Science and Technology (KNUST) has revealed that consumers of corn-related foods risk contracting all kinds of cancers. The research was undertaken by Prof. Kwofie, who is the Dean of the Faculty of Mechanical and Chemical Engineering (former) of the College of Engineering, and Dr. Anthony Andrews (now Professor) , the Head of Department (former)  for Materials Engineering . The study found that the metals used for the milling plates usually wear off when the food products are being grinded. This, the study said, opens consumers to the risk of contracting cancer, since the metals contain 'iron overloads' which are poisonous. ...
