Answer: The rate of hydration of cement depends on the fineness of cement and for a rapid development of strength high fineness is necessary.

Answer: Gypsum is added to control the "Setting of cement". If not added, the cement will set immediately after mixing of water leaving no time for placing.

Answer: Setting is the stiffening of the cement paste after water is mixed. Broadly it refers to change of fluid to solid state.

Answer: Cement (sometime referred to as Portland Cement or hydraulic cement) is one component of concrete. Cement is to concrete what flour is to a loaf of bread. Concrete is basically a mixture of 2 components: aggregates and paste. The paste, comprised of cement and water, binds the aggregates (sand and stone or grael) into a rocklike mass as the paste hardens because of the chemical reaction of the cement and water. This reaction is called hydration.

Answer: Cement may sometimes contain free lime, which may cause expansion; hence soundness test is conducted to see that even if uncombined lime is present in cement whether it is in prescribed limits. If it is within the prescribed limits then it is said to be sound and causes less expansion and cracks.

Answer: Proper storage of cement shall permit easy access for inspection and identification. Cement shoudl be stored in suitable weather, tight sructures, to protect the cement from dampness. It should not be piled more than ten bags in a stack and should be arranged in heather and stretcher fasion as far as possible. While removing the bags for use "FIRST IN FIRST OUT" rule should be applied.

Cement, or Portland cement, is a dry powder made from limestone and other materials. It is burned in a kiln and then ground finely. Cement reacts chemically with water to cause concrete to harden. There are several different types of Portland cement, designated as Type I, Type II, Type III, etc.

Answer: Synthetic artificial sweetners should be avoided especially aspartame which has been linked to brain tumours and a host of other conditions and remains controversial to this day after decades on the market. One of the byproducts it is metabolised to is carcinogenic and the other metabolites affect the brain chemistry with reports of aspartame causing seizures, mania, dizziness, brain fog, muscle cramps, tingling, numbness, insomnia, skin rashes, anxiety and depression.

My training in Chinese medicine taught me the value of preventing disease and maintaining wellness. Here in the west we focus on treating symptoms and often take our good health for granted until something happens. We don't truly understand the concept of tonics or how they can benefit our health. Tonics were once popular here in the West, until the advent of allopathic medicine at the turn of the century.

Answer: Calcareous (Lime stone obtained from mines) are Argillaceous materials (Clay, Bauxite) and Iron are teh commonly used Raw materials in the manufacture of cement.

Answer: Slow setting in cement is due to salts and chemicals in water sand and aggregate. Cold weather, less cement, high percentage of impurities, adulterated cement and improper water cement ratio. Qick setting of cement is due to addition of low quantity of Gypsum, hot weather condition, high cement fineness.

Answer: The Setting time of Cement is the time required by concrete to harden and set itself according to the formwork in which it has been placed. The amount of time taken by concrete to set is 7 hours to 10 hours depending on the conditions under which the concrete is placed in the formwork. But this does not mean that the formwork may be removed after 7 hours.

Answer: No, the color of cement does not affect the strength of cement in anyway. It just gives a proper finish to the concrete. There is a general misconception that the cement that is darker in color has greater strength, this is not true and the cement that is lighter in color not only has the same strength but also has a more pleasing finish than the cement that is darker in color.

Answer: The water cement ratio is very important with regards to the strength of concrete. The strength of concrete is inversely proportional to the water cement ratio i.e. with teh increase in water content the compressive strength of concrete decreases and vice versa.

Materials that contain appropriate amounts of calcium compounds, silica, alumina and iron oxide are crushed and screened and placed in a rotating cement kiln. Ingredients used in this process are typically materials such as limestone, marl, shale, iron ore, clay, and fly ash. The kiln resembles a large horizontal pipe with a diameter of 10 to 15 feet (3 to 4.1 meters) and a length of 300 feet (90 meters) or more. One end is raised slightly.

No. Our cement has been made easy to mix in the provided packaging without the need and extra cost of a separate mixer.

Yes, the Moon Bounce will be secured with sand bags rather than stakes. However it is HIGHLY recommended that the Moon Bounce be set up on grass whenever possible. It is possible that someone could slip getting into our out of the moon bounce and hit the ground. The cement is unforgiving when this happens. There is an additional fee for hard surface setups.

The Parallax Ez-Flow CDS is designed for the percutaneous injection of bone cement but have been optimized to work with the Parallax line of cement products. The Parallax IDS is designed for use with a proprietary cartridge cement-it will not work with vials or other types of formats.
