Shrinkage of the solution (change of volume) increases in the initial stage of hardening of the solution, gradually decreases and fades. For slurries, it almost stops at the 90-100th day. Masonry often use Portland cement (PC), Portland fast curing (PC-B), hydrophobic portland cement, portland slag cement (SPC) (Used for the manufacture of concrete and reinforced concrete, artificial stone because of its high strength), silicate cement, etc. Made from alumina cement and calcium silicate. After firing, these materials are ground, and how fine grinding is carried out depends on the quality of the finished product.
World's most popular white Portland. This Portland has a high degree of whiteness (at least 85%), a liquid grinding. White cement in concrete slabs attached to the concrete brightness and lightness. This cement is nizkoschelochnym, high strength and sulfate, so it is suitable for use in both dry and wet areas. Except for the name, the properties of cement can be judged by its labeling. The letter M indicates the degree of burden that can withstand all dried cement.
So marking M200 means that the maximum load is maintained according to the cement is 200 kg per 1 cubic centimeter. Sam Mikulak may find it difficult to be quoted properly. The most common brands of cement M200, M350, M500. Cement brand M200 has the lowest strength and is suitable only for small household jobs. In construction, commonly used cements M350 and M500. The letter A denotes the percentage of additives has given concrete. source of information. The amount and composition of impurities determine the strength and additional properties of cement. Based on the foregoing, marking M400 D20 indicates that the brand of cement holds up to 400 kg per cubic centimeter and contains 20% impurities. Such a cement, by the way, very often used in residential construction, as well as for production of concrete. It is distinguished by increased frost and moisture. A special class is formed by sulfate-resistant cement. They are less susceptible to other destructive Effects of various mineral solutions. Therefore, they are successfully used for structures located in seawater, for example, supports the docks, etc. Cement has the ability to absorb moisture from the surrounding air, losing this its properties. Therefore it is recommended to keep it in plastic bags. A good solution is also the storage of cement in large quantities, because the outer layer in contact with air forms a kind of protective crust protects the rest of the cement hydrationcontinue reading
Hypothermia and sunstroke – two enemies that can really kill you. They pursue the rights to all his way in the wilderness, from the southern hot deserts of the south, to the chilling cold of the steppes north. Hypothermia should be note that the risk of hypothermia is very large in the harsh winter conditions, but there is a certain percentage likelihood that hypothermia can comprehend a man in northern and southern latitudes at dusk. At low temperatures, the body tries to warm up, depositing blood in internal organs. This leads to a cooling in the first limb, there is a risk of multiple frostbite. Supercooling of the organism entails a number of irreversible processes.
Due to the deposit of blood in the organs, it is not so much in the bloodstream. This phenomenon causes oxygen starvation and, hence, loss of consciousness, a high probability of pathological processes until death. At the first sign of hypothermia – numbness of limbs, trying to move, to kindle a fire, jump into a natural hot springs, wrapped in skin killed earlier animal, drink hot water with fire, in a word do everything to keep warm. The case of sunstroke in warm climates with high temperature, humidity, scorching heat of the sun. During the day most likely to get overheated body. The first signs of sunstroke is a headache, dizziness, weakness. When you see these signs immediately seek shade, cool head tying her white water-soaked (in extreme cases the urine), tissue (piece of T-shirts, shirts, t-shirts). Sunstroke can cause vomiting, which leads to dehydration, and if the traveler is no water reserves, his life is placed under threat.continue reading
However, if you take small portions at the long day you asegurareis that the body uses them and the level of blood sugar is stable, so you will not feel hunger. The topic of blood sugar leads to the second method to control hunger. It is to consume complex carbohydrates, such as potatoes, sweet potatoes, oats and bran. You away from sugars or simple carbohydrates. Many believe that they should not prove any carbohydrate while you do diet slimming, but this strategy causes hunger crisis.
Carbohydrates is the stuff that the body breaks down and converts into sugar for energy. If you do not consume carbohydrates, sugar will fall and you’ll desire to eat. It is not a good way to control appetite. However, you can not eat any carbohydrate. You have to move you from the refined because they behave like simple sugars in the body.
They burn rapidly and cause a peak insulin that then causes a sudden drop in blood sugar and the consequent hunger. In addition, with the peak of insulin the body accumulate fat. I.e., that when you create an environment conducive to the accumulation of adipose tissue is precisely when you have more hunger. CEO of e-commerce often expresses his thoughts on the topic. Without a doubt, it is not good. You must eat complex carbohydrates that decompose slowly so that sugar is stable and there is not a yo-yo effect. So you’ll feel satisfied and without hunger. Carbohydrates are not the only important nutrient to control appetite. Also keep in mind to the protein. Protein takes to digest and has no influence on the level of plasma sugar as carbohydrate. In fact, maintains the feeling of fullness longer, and hormones that indicate that you have hunger are slow to appear. Protein that does best this function is that of serum, so keep it by hand to not go hungry. Now that you have complex carbohydrates and protein in the shopping list, add the water. The water calms the appetite because it fills the stomach and tricks the body. People who drink a glass of water 30 minutes before a meal, eat less. Also, if you drink while you eat, food will absorb the water and inflated in the stomach. So you’ll have the sensation of being full. However, you do not excedais in water consumption thinking that the more you take, less hungry you have, because you could dilute the nutrients. Limits you to a glass of water before meals.continue reading

Advantages of a swimming pool roof over a swimming pool cover the swimming pool in the open air in Germany must be covered, is obvious. The nights are too cold and cools the day heated up swimming pool water overnight up to 10 degrees. Now the question arises: what coverage is right for me? A swimming pool plate cover can be installed underground or on the edge of the pool as upper hallway. The underground (underground) is thus largely invisible and disturb not the overall impression from the swimming pool. For the upper floor area, you can get a version that is small and compact.
However, the pool is in an environment where many leaves in the pool may fall, the swimming pool cover is not the first choice. Then you should prefer to fall back on a pool cover. This is visually sometimes not as nice, but can come up with unique advantages. The biggest advantage is that the cover in gardens with many trees the basin before protects leaves covered in. Another advantage is that in a garden, animals such as mice, rabbits or cats run around and be protected by a pool cover from falling into the swimming pool and an involuntary death.
In addition, a pool cover protects small children before falling into the pool. Here it is advisable to incorporate a parental or lockable doors into the pool enclosure. This should certainly be the main argument for a pool enclosure because it provides the best protection for your child. Since there is already a law in France for several years, also a private swimming pool must be specially secured, it can be so, that becomes a pool cover, or a swimming pool cover in the future also in Germany the duty. An alternative is a fence if necessary, to take advantage of the swimming pool. This is already considered by many pool builders. A special case is the extension of the bathing season. A swimming pool, with a Pool enclosure is provided, the active season extended by one to two months in the spring and in the autumn. This increases the Attraktivtiat of the pool, but not necessarily the attractiveness of the garden. Generally, the opinion of a pool cover is always unique. Either you like them or you don’t like them. For a pool enclosure or against private person must individually decide the decision for themselves. No matter for which cover variant you choose, the energy saving is substantial and is thus also the protection of the environment.continue reading

Then you can further increase the depth and to build that trust to the water. 2.) This is a long process. First, you should practice the legs with a floating Board in the non-swimmer area.
Best with the “frog, bird, fish” method. We put on the legs like a frog, they make far apart like a bird and fast and powerful together like a fish. Then, you should practice the arm stroke with a floating noodle under the armpits separately. Only the coordination exercise and already is one the German swimming badge seahorse closer. 3.)

Touching a dolphin or swimming in a dolphin group risks for all parties involved, which are the least aware. Swim with and touch dolphins (usually bottlenose dolphin, Tursiops truncatus) has become more and more popular, with wild animals, with prisoners in the Dolphinarium, Dolphin therapy or in one of the Petting pools popular especially in the United States (Petting pools). Many of the well-intentioned, often very naive to the encounter with these animals rising up \”Dolphin swimmer\” forget that the bottlenose dolphin, like all others of this small cetaceans, is a predator. A predator, which dominates the probably most developed form of hunting in the entire animal Kingdom, the hunting of the social association with precise task sharing and coordination. Others including Frank Ntilikina, offer their opinions as well. No one would get the idea, to handle adult lions, whose hunting technique is very similar to that of dolphins in the wild or in the Zoo, to caress them, or to be carried by them, it would be deadly. For unknown reasons, wild show Dolphins however people usually hardly aggressive behavior, although they with each other and against other species, such as Bottlenose dolphin in harbour porpoises, a considerable, sometimes with deadly consequences Aggressionspotenzialan the day can create.
Also child killings have already been noted when bottlenose. Man bottlenose, but also other dolphin species behave, but often curious and playful, even repeatedly, there that they save people from drowning or shark attacks.
