Precast Concrete and Sustainability
As a manufactured product created under controlled conditions in the plant, precast concrete generates low amounts of waste, and the waste generated has low toxicity. 2. Reuse and repair products Precast concrete panels can be reused when buildings are expanded. Concrete pieces from demolished structures also can be reused in other .

Chemistry for Biologists: Metabolism and energy
The energy 'hump' shows how much energy reacting molecules must have for a 'successful' collision, one that leads to reaction. The formation of an activated complex requires energy to bring molecules together in the correct orientation. Therefore, it is always an endergonic reaction.

Concrete: Advantages And Disadvantages
The effect of the admixtures vary depending on the different type of mixes and their purpose. The concrete mix for a precast wall unit was also analyzed using these admixtures. Based on that analysis we can conclude that this admixture has the desired effect by decreasing the energy by 10% by volume of concrete.

Energy: Scientific Principles
Nuclear energy may be defined as the energy found within an atomic nucleus or as the nuclear binding energy. If we take the helium nucleus, the mass of its parts (two protons and two neutrons) is less than the mass of the nucleus itself.
Concrete and CO2
Concrete reabsorbs CO2. During the life of a concrete structure, concrete can reabsorb CO2. This is done through a process known as carbonation, a chemical process where atmospheric CO2 reacts with the Calcium Oxides (CaO) in the concrete to form calcium carbonate (CaCO3).
Is concrete bad for the environment?
As a result, global demand for concrete is only going to rise, therefore we really need to come up with a way to lessen the impact of the concrete industry on the environment, potentially using one of the methods detailed above.

Concrete Thermal Energy Storage for Solar Thermal .
Efficient energy storage is vital to the success of solar thermal power generation and industrial waste heat recovery. A sensible heat storage system using concrete as the storage material has been developed by the German building company Ed. Zuumlblin AG and the German Aerospace Center (DLR).
Heat Transfer (Energy Engineering)
Temperature is a measure of the kinetic energies of the particles such as the molecules or atoms of a substance. In a liquid or gas, the kinetic energy of the molecules is due to their random translational motion as well as their vibrational and rotational motions.

Cement Technology Roadmap 2009
Cement is the essential "glue" in concrete, a fundamental building material for society's infrastructure around the world. Concrete is second only to water in total volumes consumed annually by society. But producing cement also coproduces CO 2, leading the cement industry to produce approximately 5% of current global manmade CO 2 .

Mixing and Transporting Concrete
concrete, a longer mixing time is required. Transporting Concrete. Transporting the concrete mix is defined as the transferring of concrete from the mixing plant to the construction site. Keep in mind that not all concrete is mixed on the actual construction site and could require some significant travel.
