The renowned Pozzolana cement of ancient Rome came from the mining of Volcanic Ash, which was abundant in aluminosilicate minerals. (Lea, 2015) This specific cement, or indeed any aluminosilicate that react with lime in water to form cement is still referred to as Pozzolana or Pozzolan. In 1756 in Devon, John Smeaton developed a hydraulic lime which would go on to be succeeded by Portland cement (Milana, 2011). Further progress took place throughout the 1800s, but the actual concept of Portland

CE 2020: Construction Materials Report on Chemical composition and Structure of CSH Arjit Soni ES13B1005 Introduction: The C-S-H gel is the most abundant reaction product in cement, occupying about half of the paste volume, it is also responsible for most of the properties of cement paste. This is just not because it is a strong or stable phase but because it forms a continuous layer that binds the cement particles together. All the other hydration products of cement form discrete crystals that

I was born with a keen curiosity and I find it very difficult to stop wondering how things work, especially if it includes STEM. Born and raised in a poor family where opportunities were both rare and expensive, I struggled as much as I could to never stop being fascinated by nature, and in part, I have indeed been successful. In fact, I believe that this struggle helped me outrank everyone during my high school and help me achieve significant accomplishments, such as being finalist in my country’s

Alka Seltzer Dissolving at Different Temperatures The variable that I will change will be the temperature of the water that the Alka Seltzer is put in. For my results I will measure the time taken for the Alka seltzer tablet to completely dissolve in water at different temperatures. Input variables: * Varying surface area of Alka-Seltzer tablet, i.e. if cut into smaller pieces or crushed it will increase the surface area. (If the surface area is increased (more powdered) the rate

Ankur Sindhu Sep 20, 2011 CHEM 182-DL1 Prof.: Dr. Nidhal Marashi Lab 1: Colligative Properties & Osmotic Pressure Purpose: The purpose of this laboratory was to gain an understanding of the differences between the freezing points of pure solvent to that of a solvent in a solution with a nonvolatile solute, and to compare the two. Secondly, osmosis was to be observed to gain a proper understanding of how the principal of dialysis functions. Procedure: 1. Make

The topic that was chosen was turbidity. Turbidity is the pollution in water. Turbidity is commonly associated with cloudiness or haziness in water. The pollution that studied was dirt and how it affected fish. It is important because it is killing our wildlife. There needs to get teams of people each month going out and cleaning up the water. If the dirt in the water affected the fish then the experimental group would die. During the time of researching this topic, it was discovered how different

Naphthalene and benzoic acid are two compounds studied in this experiment. Sodium benzoate is also an important substance involved in the separation process. The separation technique used to extract the different compounds of a heterogeneous mixture is based on solubility and density. Regarding naphthalene and benzoic acid, their chemical properties differ from one another (Separation 1). The detailed separation process of naphthalene and benzoic acid, found in a mixture, follows. First of, when

Archimedes was requested to check for the presence of silver in the king’s gold crown. Archimedes came up with the idea to get the solution as from when he was going to take a bath. Archimedes had stepped into his bathtub that was filled with water and caused it to overflow. Archimedes filled a bathtub with water to the brim with pure gold at the equal weight of the king’s crown. He then removed the gold and placed the kings actual crown into the bathtub. Archimedes knew that if there were traces

My question is, which mineral will make the water most acidic? My hypothesis is, if I use Granite, Obsidian, and Rhyolite to make the water acidic, then I believe rhyolite will make the water most acidic. In this project I filled three cups with a half cup of water, then I tested the pH of water. After that I put the rocks in different cups, and I waited for ten minutes. Then I tested the pH. pH stands for potential Hydrogen. According to the pH scale the most acidic is one and the most basic is

The member’s in the 8th grade science class is trying to find out what is in this mystery mixture. All of the class has to find out what is in the Mystery mixture. But there are some things that the entire 8th Grade has to know before they start their testing. There are physical and chemical properties and you have to now those before they start testing their Ideas. The physical properties are the first one. The names of them are, change of smell, appearance in the substance, Taste, touch and color
