Green concrete is the future trend. Recycled concrete aggregates use of fly ash, furnace slag and silica fume to reduce the cement content

and produce green concrete. So use pozzolans materials can help concete be strength. Earth' health is your health .

Green building-material mean for the concept of sustainable development, so use more recycled material is more important.

Using slag and fly ash not only reduce energy consumption but also make workability and compressive strength better.

Next, using recycle aggregate replace part of natural aggregate. Finally, Green must be penetrated into the environment each of us.

Find more recycle material or new green material can use in concrete is our mission.

Green concrete design is a new method to recycle waste materials, reduce CO2 emission and utilise pozzolanic material to replace

Portland cement, such as blast furnace slag and fly ash. We know how to solve problems of concrete, but it is not enough. The environment

is changing now. I think that do not destroy nature environment is more important than you predict. So to protect earth

is our responsibility and we really have to do.

Green Building Materials is the protection of the child's future,and sustainable development of the Earth is also very important.

Green Building Materials is a great product.

The first report in English came to power, a bit not used to.

After reading everyone's briefing, the green concrete of the Earth is really important, if we do not pay attention really destroy the Earth.

The future, if greater use of green concrete, the earth's warming will be reduced.

The first paper point out the energy consumption of cement production make up more than 90% of the total energy consumption when constituent

and production. So we reduce concrete can help environment to reduce CO2 emission.

The second paper try to make 5 different green concrete.The result shows Concrete with a high amount of fly ash failed in

Resistance against frost deterioration and Carbonation and Chloride ingress. So although we want to reduce co2 emission,but we can't fill

After 88 floods,we should pay attention to environmental protection, but also to the development of green concrete.

with too much fly ash!

Concrete in the past to the future has played an important role, because good or bad the quality of concrete buildings represent a long life

With the development of technology requires not only the durability of concrete but also take into consideration the environmental

protection issue, so the green concrete will be our task to face the future, but also we want to learn.

Green concrete in the future must be the trend,forvthe environment, the traditional concrete for the environmental impact of large,

just ordinary concrete by the excessive amount of cement used in excess of carbon dioxide emissions caused by the greenhouse effect

so in the future green building materials must be the civil engineering construction trend.

We know green concrete is important in concrete industry. Because concrete leave an enormous environmental footprint on Planet Earth.

We should use more recycled materials to replace existing material . So we can think how can we do?

Now many scientists is researching about green concrete. Green concrete achieve is not a dream. So we should try hard together.

The green concretes have the advantage, energy conservation,

energy conservation, Greenhouse gas reduction, conservation of natural resources and land and educing landfill costs.

We can use Pozzolanic material, Recycled concrete aggregates and the wastes are utilized again

After finishing reading the classmates' report, there is further understanding in doing Pozzolanic material and the green design concrete.

Save a lot of time to read these relevant articles too, can probably understand what the content is being narrated at once .

Being can probably anticipate designing the concrete green by the contented is a trend of the trend in the future .

We can use pozzolanic to fill the small hole.

In the future, green stuff will use a lot to decrease the co2 produce.

Now how to defend the earth is the important thing to us.
