T.Ramlochan, et al. (2003) the expansive behaviors of heat cured mortars containing pozzolans and slag was investigated by the authors. In almost all the mortars, the addition of any amount of pozzolans and slag to the mixture usually reduced the onset of expansion, the rate of expansion, and long-term expansion. However, the efficiency of a particular pozzolan (or) slag in controlling expansion may depend on its Al2O3 content. Metakaolin, which contains a higher amount of reactive Al2O3, was the most effective at controlling expansion at relatively low cement replacement levels. Slag and fly ash which are also sources of Al2O3 were also effective at suppressing expansion at higher replacement levels. Silica fume was less effective at controlling …show more content…
For comparison, a commercial MK of high purity was used and the strength development of Metakaolin concrete was evaluated using the K - value (efficiency factor). The produced Metakaolin as well as the commercial one imparted similar behaviour with respect to the concrete strength. Both conventional and commercial Metakaolins demonstrate very high K-values (close to 3.0 at 28 days) and are depicted as HR pozzolanic materials that may lead towards concrete production with an exceptional …show more content…
The Metakaolins examined appear to have a catalyzing effect on cement hydration, leading to acceleration in the reaction rates, an increased in cumulative heat evolved during early hydration and for some cements apparently an increased intensity in heat evolved during certain periods of each hydration. The surface area of the Metakaolin also seems to influence these early hydration behaviors, with the higher surface area material producing a greater rate of heat evolution, greater cumulative heat, and greater intensity during early hydration. It is proposed that the Metakaolin may act to enhance dissolution of cementitious phases and or by providing nucleation, in addition to increasing the solubilized aluminium in the system at early
I spoke with Michelle Chilies-Kusiolek, Chief (RMO). Ms. Chilies Kusiolek declined to give age, race, color or gender. She stated that she is aware of the incident and the alleged racial slur. She contacted the Human Resource department to give her guidance on what would be the appropriate course of action.
CCIB received a call from Shauna. Her son Kai Crupt (DOB 10/05/11) attended this day care. Shauna reported that this summer her son came home and told his parents that teacher Yolanda pulled his hair. They thought maybe it was an accident. A few weeks again Shauna got off work early and picked up her son (Around 1:30 PM).

Greater Akialoa Many different species have become extinct throughout the years, the Greater Akialoa is one of them. It lived on three Hawaiian islands. The causes leading up to extinction is forest clearance and diseases. The Greater Akialoa or the Hemignathus ellisianus are extinct.
Candidate Krombash briefed a slow and drawn out five paragraph order which took two minutes to get through the mission statement, sadly enough his mission statement was unsatisfactory. There was simply too much information, most of which was repeated two or three times throughout the order. SNC finished his order at 4:03 into the ten minute evolution. SNC started the scenario by giving away all of the fire teams weapons to the security man and exposing themselves to the enemy. Throughout the execution, Candidate Krombash communication was poor.
When examining the case of the State of California against Dr Zhou, we can clearly conclude that the HIPAA law of which was convicted of violated is not just words written on paper to buy patients' confidence, it is meaningful law set in place to protect patient privacy and any ones violating this law, regardless of your position in the health care field can be persecuted punished for violating the law, even in the absence damages evidence resulting from the violation of the law. The purpose of this post is to discuss the case of the State of California against the physician, Dr Huping Zhou, in this post I will review the HIPAA law, penalties for violation of the law and why I felt that Doctor Zhou was very fortunate for his punishments four
When examining the case of the State of California against Dr Huping Zhou, we can conclude that the HIPAA law is a meaningful law set in place to protect patients’ privacy, and any one violating this law, regardless of your position in the health care field can be persecuted, punished for violating the law, even in the absence damages evidence resulting from the violation of the law. The purpose of this post is to discuss the case of the State of California against the physician, Dr Huping Zhou. In this post, I will review the HIPAA law, the penalties for violation of the law and why I feel that Doctor Zhou was very fortunate to receve the punishments four months in prison and just $2000 in fine. As a physician, a researcher of UCLA School
As much was conducted throughout this lab, the projected completion of this lab displays that ultimately, the higher the temperature of the water, the faster the dissolving rate of the Alka-Seltzer is. In other words, the hotter the water temperature the quicker the tablet dissolves within the water in regards to the amount of time it took to dissolve. Furthermore, this experiment helps to explain that, if water is taken at a higher temperature and Alka-Seltzer is placed within the water, the Alka-Seltzer will take less time to dissolve because the higher temperatures cause the tablet to melt at a quicker rate. This compares to when Alka-Seltzer is placed in colder temperatures, where instead it takes more time to dissolve, because the lower
1. The girl in GA. Going based off of the information that was given, the TV station has violated the family’s rights not only by going against the law in the state of Georgia that passed the law that made it illegal to broadcast the name of the rape victim. So based of the father’s reaction, to what the TV station did, he has every right to sue and I would side with him. 2.
The descriptions of the area are dire racism, depression, violence and crime, mental illness and radical youth are just some features. The health conditions are also bad although Kaukab needs surgery urgently, there is no place at the hospital, and because of the overcrowded immigrant quarters and poor nutrition, tuberculosis has reappeared when the British authorities had thought that the illness was eradicated in the 1960s.
The Zhou dynasty was in power between the years of 1046 - 256 BCE. It was longest dynasty. It came after the Shang dynasty. The Qin dynasty took it over and ended it. It ended in 256 BCE when the Qin state took over the city of Chengzhou.
Ryan Malakie Principals of Environmental Science 10/8/2015 Pueraria Montana (Kudzu) Pueraria Montana or kudzu is a vine originating from the pea family, which can grow at a blister pace of one foot per day. Kudzu has compound leaves with 3 leaflets each measuring about 10 centimeters wide and 10 centimeters long. The woody vine of the plant grows to be about 2 centimeters in diameter, producing small purple flowers that smell like grapes. Kudzu is considered to be an invasive species in the United States due to its fierce growth that blankets the landscape, out-competing any native species.
The act of racism has been present in every society throughout history. Discrimination of other groups based on their different descent and ethnicity. These forms of hatred and negativity are based off old fashion values and traditions. People of different cultures believe there’s is superior, this belief in superiority may take the form of ethnocentrism or prejudice. In early Vancouver, the Chinese and First Nations experienced this disparagement first hand.
The case of Korematsu vs. The United States was the case concerning the constitutionality of Executive Order 9066, which had the effect of relocating all people of Japanese ancestry on the west coast and Hawaii to internment camps. This case was to set an example of others such cases, and shows how exactly this war time was affecting the citizens of america.(Short Answer)A Japanese-American citizen named Fred Korematsu claiming that his rights as an American citizen had been violated, along with thousands more Japanese-Americans civil rights. However, the Supreme Court voted a loss to Korematsu 6-3. “ It should be noted, to begin with, that all legal restrictions which curtail the civil rights of a single racial group are immediately suspect.
The Problem: How does temperature affect the dissolving time of an antacid tablet? Antacid tablets are medicines that help neutralize the acid in your stomach. Antacid tablets are made of numerous numbers of components, such as sodium bicarbonate (baking powder), magnesium hydroxide, critic acid, and many others. When Antacid tablets are placed in water, they undergo a chemical reaction, where the sodium bicarbonate breaks apart to make sodium and bicarbonate ions. When the bicarbonate ions collide with hydrogen ions, it produces carbonic acid.
