Fly ash

Figure 2. 3. Role of fly ash in concrete + Source: NTPC (2014). 2.3.4. BENEFITS OF USING FLY ASH IN CONCRETE 2.3.4.1. WORKABILITY OF THE CONCRETE Fly ash particles are spherical in shape with high fineness and low carbon content this reduces the quantity of water required for a given slump (Zulu, 2014). This means that a mix with Portland cement would have a higher water content of the same workability compared to the fly ash mix. It is estimated that each 10% of fly ash added to a mix reduces the water content by 3%, this is dependent on the nature of the ash and other parameter of the mix (Thomas, 2007). Its spherical shape helps to reduce the friction between aggregates and between concrete and pump line and thus increases…

material. Concrete is an almost universal material. It can be used in so many ways, and achieve many different looks. It can be used architecturally by being the exterior support of a building, or by being the exterior itself. It can be used interiorly by being incorporated into the floor, walls, ceiling, furniture, etc. Concrete can be colored, textured, and can have aggregate added to it. The possibilities are never ending. The basic recipe of concrete is portland cement, water, and…

Abstract: The study investigated the workability, and compressive strength properties of the concrete produced by replac-ing 5%, 10% and 15% by weight of ordinary Portland cement with Sawdust Ash (SDA). Slump test was carried out on the fresh concrete and compressive strength test on hardened concrete. The concrete cubes were tested at the ages of 3, 7, 14 & 28 days. The results showed that Sawdust Ash is good with use in cement. The slump decreased as the Sawdust Ash content increased…

Ten days has passed by since then and Ash-well, he was gradually making progress, learning through his mistakes and mixing in some of the lessons he had learned through meditation into his daily routine. Patience was the key to his improvement because his aura couldn’t properly flow through his body under a lot of stress, he finally realizes that. Rather than forcing his aura, he approached the matter with a cool head, reducing the stress and taking deep breaths whenever he felt frustrated.…

"Also, what’s a Saiyan? A new type of Pokémon?"’ … … … Ash noticed the group’s expression. They were completely taken aback by unexpected turn of events. More so, that he didn’t expect Caulifla to march up straight at him and grab a handful of his jacket collar before pulling him towards her face in a fit of rage. "What the hell are you saying you don’t know who we are, Ash?!" she practically yelled at his face. "Caulifla, calm down!" Cabba rushed over and tried to pry the fuming Saiyan off the…

According to historians this celebration is dated back thousands of years ago to pagan celebrations of spring and fertility. Also including the raucous Roman festivals of Saturnalia and Lupercalia and when Christianity moved in to that area When Christianity arrived in Rome religious leaders decided to merge these popular local traditions into the new faith an easier task than abolishing them altogether. As a result the excess and debauchery of the Mardi Gras season became a prelude to Lent the…

Carnaval is a holiday lasting five days, usually taking place some time during February. It is a festive, colorful celebration that offers a chance to get out all your “pent up energy”, before the forty day fast Catholics take up known as lent, lasting from Ash Wednesday to Easter Sunday. In this fast, hardcore Catholics don't eat meat for the entire fast, and as the word Carnaval suggests. (Carnaval is formed from a latin word meaning take away or goodbye to flesh). Carnaval is celebrated by…

Determining the affects of natural selection on gall fly (Eurosta) larvae from different predators Ariel O’Neil Biology 1020H Abstract This lab was done with the objective of determining if directional selection causes early larvae death in the gall fly. By first examining the parasitoid wasp and birds predatory actions we can hypothesize and predict the smaller galls will be most likely to survive directional selection. To figure out if this is true or not a large variety of goldenrod galls…
