Anime With Love Making
material is recommended for its insulating qualities of cold and heat, its industrial production can be a manual or used the dimensions are: 10x20x40 cm. 15x20x40 cm. 20x20x40 cm.
In the world there are many types of materials that can make the block, but are used mainly cement and sometimes hollow clay blocks Pressed hollow.
always useful life varies depending on the characteristics of the environment where this technique is used for construction, and manufacturing the same, but a cement block hollow generally expected to have a lifespan of 50 to 100 years.
What synergy?
There are 4 general processes for the production of cement which does most of the blocks in Mexico. The first is the operation which is done at sites with explosives, the second is transportation, which are used such heavy mining trucks, the third is the grinding, which operates by means of scrimmage and passes cylinders grinding, a process which employs 40% of the energy required in production, and the fourth is the grind.
For all these processes there are no energy savings.
What happens at the end of its life? These blocks are easy to re-use for 2 reasons: the first is due to the material, concrete is crushed, and the second by the size of its parts, and the very fact that they are parts, makes it easier to process.
In some countries are using new designs of blocks with horizontal and vertical holes that allow access to pipes and wiring installations, which makes construction more efficient and less costly.
The Project Certification Program (Product Certification Project) offers Green Building Council Of Australia (GBCA ) there are no clear definitions and restrictions for this material. But it is useful to consider that there are specific parameters for the concrete, the main component for the construction material of which we speak. One type of review to the concrete and its characteristics ( Concrete Credit Review ), which express the 4 "stars" who have to qualify the concrete. Qualify as "Mat-5 concrete" when will give the last star.
BLOCKS Hebel
The construction blocks that are manufactured and distributed by Hebel company are modular concrete block structural walls and solid walls are constructed with high thermal insulation, which can decrease your costs for heating and air conditioning. 
Blocks employ a traditional building, which is also anti-seismic. 
Other benefits of these blocks are allowing a cleaner and faster construction, walls are resistant to moisture, and she ends up coming out cheaper because construction per m2 are used only 8 blocks. The "Hebel blocks" have a much greater fire resistance than normal concrete wall or (F 180), all the walls of 150 mm or more, have a 4-hour fire, which is the highest level fire resistance may now also does not rot or cracks over time.

Hebel block is a material certified by the Green Building Council Of Australia (GBCA) with the sticker "label Evironmental Choise" and ceilings and panels that also offers the same company, due to its characteristics.

Block Acrylic construction
PMMA (Polymethylmethacrylate) or known as acrylic plastic is a variant of a more flexible and easy to work.
environmental impact production
Only 4% of global oil is used in plastics production.
needed:
100 kilograms of oil to produce 1000 bottles,
230 kilograms of oil to produce 1000 bottles
"It takes 57% less energy to produce plastic bottle glass "
environmental impact transport
You save up to 39% of the fuel to transport in acrylic comparison of glass.
"Plastics generally constitute 7% of municipal solid waste"
Maintenance
Benefits
Acrylic is a 100% recyclable.
Transparency of around 93%. The most transparent plastics.
Excellent thermal and acoustic insulation
Light in comparison with the glass (about half), with a density of about 1190 kg/m3 is only slightly heavier than water.

Materials: Gravel
GRAVEL is a material is caused by fragmentation of the various rocks of the crust, naturally, as causes of rivers, dry wells, sedimentation or banks either by removing artificial crushing rocks.
The reuse of gravel produced by debris on the roads can be and streets, creating a resistance and impermiabilización, generating greater durability.
Some of the properties of the aggregate is that it gives the thickness and consistency of the concrete, so the quality is very important to have a good result

generally encouraged the use of local materials, and due to its weight, transferring involves high energy consumption . The largest benefit lies in its longevity, one of the most sustainable materials.
gravitates The most noticeable impact in the extraction stage, caused by variation in the field, the change of landscape and ecosystem. For general use, this type of material is causing major problems.
CERTIFICATION
The new Framework Evaluation of product certification systems was launched in June 2009. Products and materials that are certified by GBCA (Green Building Council Australia) which was created in 2002 is a recognized certification system which will have greater access to "deemed to satisfy" the status of compliance within the Green Star
Environmental Impact Assessment (EIA)
Proponents must activity predict changes that occur in the middle, and suggest corrective measures prevent or mitigate as far as possible the inherent disorders that are caused, including a plan that will restore the physical and biological environment to its original state.
The reuse of gravel produced by debris on the roads can be and streets, creating a resistance and impermiabilización, generating greater durability.

Materials: Quarry
The quarry is a stone formed in the earth millions of years. It is classified among the magmatic formations, which were solidified slowly trapped in the heart of the mountain. The darker color are the clearest.
The material varies according to levels:
1) Levels pyroclastic products of various colors, consisting of fragments of pumice and volcanic glass.
2) little pink Cantera consolidated in its pasta with white pumice and andesitic volcanic rock fragments, these latter are angular or rounded and of various colors. It is a very soft material.
3) Quarry rose very similar to the above but welded (hard) as above, there are wide fractures. Is compact.
Process 
The quarry natural, hand-carved in the traditional manner with the aid of tools current technology, it goes through a process of timber extraction, import and placement.
also has properties in the area:

What synergy?
All quarry has a shelf life, and once drained, the abandonment of farming causes of environmental problems, mainly related to the destruction of landscape and visual pollution.
How does the welfare of the occupants?
With its diversity of colors, the quarry can be used in different elements. For example in facades, fountains, contours pool, floors, interior walls and main entrances.
also has properties in the area:
- is not slippery.
- ice resistant and high impact.
- have very low values \u200b\u200bof erosion.
- Meets the essential objectives of the construction, resistance to the elements of nature, availability and, above all, the durability that the human being seeks.
Barriers level mining:
- Australia, despite being a country rich in natural resources, not noted for its richness and variety of natural stone.
- The few natural stone quarries are spread across Australia. Distances and difficult access from the quarry to detract transportation cost.
- Local companies have not developed the economies of scale that enable them to produce more efficiently.
