What is difference between first stage and second stage concrete used in powerhouses concreting?
In power house concreting during the installation of turbine units in their final location a second stage concrete is poured in order to embed the turbine units. A second stage concrete shall be non - shrinking,self compacting with quick setting admixtures for an early strength development
How do you increase grade of existing concrete?
In basic terms, you can not. you can strengthen a reinforced concrete beam by application of a steel plate/frp up to a point where the area in the stress block under compression is at a max. allowable limit as stated in the code you are using. At this stage, the concrete is close to a crushing instantaneous failure and the beam can not be strengthened further.
The difference between setting and hardening in cement?
SettingSetting begins to occur after the concrete is mixed and even before pouring. The cement in the concrete begins to stiffen after mixed with water. The concrete is beginning to change from liquid form to solid form. During the setting process, the concrete does gain strength, which is the beginning of the hardening process. When the water ingredient is added to the concrete mix, the concrete is still pliable and flexible, sort of a paste. There is two stages of setting: initial and final setting. Initial setting is when the concrete loses it flexibility and begins to harden. Final setting is when the concrete can sustain some load, but still has some moisture within the mixture.HardeningHardening of the concrete is the stage when the mixture gains strength. The cement ingredient begins to attach itself to the aggregate as the water dries off the mixture. The hydration of water is what starts the hardening process. It generally takes five to seven days for the concrete to complete the hardening process. The easiest way to increase the strength of concrete is to add cement to the mixture. The more water used in the mixture, the weaker the concrete and it will also delay the hardening process. Once the concrete has hydrated all the water from the mixture, the hardening process is complete and the concrete is as strong as it will get.
How do you polish concrete?
Concrete is polished by grinding with successively finer grades of abrasive discs. The initial grind removes larger imperfections and can be used to grind deep enough into the aggregate of the concrete to show the colour and pattern of the stones. This depth of grinding is more expensive. Later grinds are are finer and the process can be stopped at any stage depending on the level of finish required. Ground or polished concrete is sealed afterwards and can be slippery. The equipment may be hired in order to do it yourself but keep the following in mind: * The grinding discs can be a significant part of the expense, * The concrete may have variations through it that will only show up on grinding * There is skill involved in producing an even finish
Can you use multi stage thermostats on single stage units?
Yes, only use the first stage.
What is the third stage of Jean Piaget's cognitive theory of development?
Concrete operational stage: from ages 7 to 11 (children begin to think logically but are very concrete in their thinking) Children can now conserve and think logically but only with practical aids. They are no longer egocentric.
What does Lego teach children in concrete operational stage?
During the Concrete Operational Stage, children learn to think logically and manipulate symbols. Legos teach children how to manipulate monomers (one lego) to create polymers (lego castle...idk). They learn to think operationally. Hope that helps...
What is jean piaget known for?
Jean Piaget was a French psychologist who is known for the developmental stages he created from studies he did based on the development of his own children. From this he created four stages of development that he assumed most children went through. These stages were: the sensorimotor stage (from birth to age two: the child learns to use each of their 5 senses), the Preoperational stage (ages 2-7. this is the age were children tend to believe things to be animated, such as the belief in imaginary friends or that planes fly by magic. Logical thinking is not very strong in this stage and they tend to be egocentric), the Concrete Operational stage (ages 7-12; the child begins to think more logically, but their thought are not very flexible. They are less egocentric), and finally, the Formal Operations stage (from age 12 on; the child can now think logically and begin abstract thought).
What are stages of cognItive development?
stage 1: sensorimotor stage 2: concrete operations stage 3: preoperational stage 4: formal operations

When was logic and reasoning happening?
Should be happening all the time. Some people never reach the stage to think logically or to reason things out as a part of critical thinking. By the age of 15 most people should have this ability, but don't.
What are the properties of cement?
concrete making is just not a matter of mixing ingredients to produce a plastic maas but good concrete must satisfy performance requirements in the plastic stage and also in hardened stage.
What is the concrete operational stage?
The concrete operational stage begins around age seven and continues until approximately age eleven. During this time, children gain a better understanding of mental operations. Children begin thinking logically about concrete events, but have difficulty understanding abstract or hypothetical concepts.Logic:Piaget determined that children in the concrete operational stage were fairly good at the use of inductive logic. Inductive logic involves going from a specific experience to a general principle. On the other hand, children at this age have difficulty using deductive logic, which involves using a general principle to determine the outcome of a specific event.Reversibility:One of the most important developments in this stage is an understanding of reversibility, or awareness that actions can be reversed. An example of this is being able to reverse the order of relationships between mental categories. For example, a child might be able to recognize that his or her dog is a Labrador, that a Labrador is a dog, and that a dog is an animal.
What are the four stages of cognitive development?
Answer: The Servomotor Stage 0-2 years, which the infant learns many reflexes, The Preoperational Stage,ages 2-7 years old, where language is first used with meaning, the Concrete Operational Stage, ages 7-11 years old, in which the child is able to grasp at logic, but not at every aspect, and is still concrete in thinking, and then Formal Operational Stage, 11 + years, in which the teen starts to think abstractly.
Between the ages of five and seven children experience significant changes in a period of transition from?
The stage of preoperational thought to the concrete operational stage.
Is appearance a concrete noun?
No, appearance is an abstract noun. You can see the singer appear on the stage, your food appear on your plate, or flowers with a pretty appearance, but you are seeing the person or the things, not their appearance. Their appearance is something you know.
