Stones Construction: Sandstone
L to sandstone or psammitic is a type clastic sedimentary rock, varying in color, containing sand-sized clasts; sandstone has been in outside the Earth's crust . After the shale is sedimentary rock more abundant and constitutes about 20% of them.
grains are coarse, fine, medium, well rounded, detrital texture or plastic. Quartz is the mineral that forms the quartz sandstone, but the sandstone may be entirely composed of rock or coral. The glauconitic green sand or sandstone containing a high percentage of the mineral glauconite. The arkose is a sandstone range in which the feldspar is the dominant mineral in addition to quartz.
The color varies from white, in the case of the sandstones formed virtually pure quartz, almost black, in the case of ferro-magnesian sandstones.
The sandstones are among the most porous consolidated rocks, sedimentary quartzite although some may have less than 1% voids. Depending on the size and arrangement of empty spaces or pores, the sandstones show varying degrees of permeability.
quality sandstones are durable. The rock has a good fire, and in this respect, is superior to most of the rocks used for building.
This resource is characterized by its lajosidad. This property is a feature that encourages the use of this rock in the construction applied on floors, sidewalks and walls.

Uses of sandstone
This resource is characterized by its lajosidad. This property is a feature that encourages the use of this rock in the construction applied on floors, sidewalks and walls. usually presents no lajeables also blocks that can be exploited for the construction of fences or walls.
also for having low cohesion, ie little compaction, sandstone allows its use in another application, making handicrafts by modeling the rock
into sandstone can be found in different areas of the province of Misiones, but its greatest expansion includes the towns of Candelaria, Corpus, Apostles, and especially in San Ignacio.

An entrepreneur who builds from the natural
In the province of Cordoba Summit , for three years, Juan Manuel Vazquez began to build natural homes. This year already has three confirmed projects.
some years, Juan Manuel Vasquez-known agronomist in Summit as "natural homebuilder. Is that in 2007, after making a survey of the olive oil industry, found a significant loss of quality in the care of these foods.
"Investigating how extreme weather countries working with the food stores found that many did so in natural building houses mainly by two issues: thermal and humidity regulation. So it was with my base agronomist specializing in soil I started researching this topic and my career took a turning point, "Vazquez told a Commerce and Justice.
In his words, from that moment began a "slow process of training and research through two courses with Jorge Belanko (Argentina's benchmark ) and taking online courses to people of Oregon" (U.S. .)
"After many hours of study, passion and constant learning, we came today, along with architect Gaston Iglesias, to approve the first plans for building a house of raw land in the town of La Cumbre thanks to the willingness of the mayor and the secretary of Public Works to inform and internalized in the issue, "said Vazquez.
He added: "I knew very little about the subject. For me only served to cultivate land and crops to take returns. Today we plan to grow wheat in mind to build straw bale, grain yield is a bonus. "
- We are building in for Summit people who are very involved with the environment. This year we have three confirmed projects, we will demand nearly eight months in total.
- What is the cost of a house like this?
- are undoubtedly much cheaper than traditional homes, up to 40 percent cheaper. For example, compared with a cement block building, is taking in this area at a rate of 1,200 pesos per square meter only with the workforce, regardless of the material. In the case of natural vieviendas be paid about 1,600 pesos per square meter with labor and materials included. As the construction time is estimated meter per day. However, the greatest benefit is given by the health of those living inside.
- What projections and your expectations for this year?
- Ensure that the natural construction between the Building Code La Cumbre. addition, keep working and studying on the subject and work to develop more houses wheat straw bales made by us, that do not have to travel far.
mud House:
healthy spaces, inward and outward
A industrial building and the logistics of transporting materials is attributed more than 40 percent of global warming. The Kyoto Protocol calls for 2050 to reduce the consumption of cement in a very high percentage.
"Each new structure raises an impact on their environment, both by his presence and by the resources and materials involved. In building used natural raw materials (clay, sand, straw, wood, bamboo, etc.) According to the area to create healthier spaces inward and out. If we consider the complete cycle of the elements used in construction, we see that the materials industrialized / modern become trash, while natural materials / traditional return to Earth without major damage, "said Jorge Belanko, teacher and trainer on natural structures.
According to the specialist, an important aspect of this construction is related to the resources it consumes a structure during its lifetime. The power requirement for lighting, heating, cooling, is a key point in any home, regardless of the materials that has been built. On these issues, permaculture about many techniques and systems that enable the efficient use of energy and responsible handling of waste (reduce, reuse and recycling). "Every time is bigger than the current value to its knowledge of our ancestors around the building," he concluded Belanko.

- Who are the main targets of these natural home?
- The truth is that we can talk about a wide range of properties that would improve the lives of all occupants regardless of their rank. JOINING Can social houses for low-income plans (as recently done in Belanko Jorge Roldán, Black River) or really palaces of raw land as there are many examples in Morocco. Currently, we build homes for middle class.

Alternative Energy in Sustainable Building (2nd Part)
The types of equipment that can be used to transform solar energy into heat are mainly of 2 types: compact and separate system (split).
separate systems in general are more suitable for applications where you need to meet more than one function, such as hot water (DHW), heating and warm pool, with the same team. ACS applications only, compact devices are more than suitable solution because they provide up to 90% of the energy with a very convenient cost.
split Team
Team compact
present a comparative analysis of operating cost of different ways of providing hot water and recovery term of the investment.
ES = Energy solar, NG = natural gas, liquefied gas filling GL =, EE = Electric Power
The graph shows the desirability of installing solar systems after the initial investment does not have operating costs and make us save money.

WATER: non-renewable resource?

We traveled the end of a summer where the pressure comes back on appeal los problemas a enfrentar a corto plazo. Muchas de nuestras localidades tuvieron inconvenientes sobre la disponibilidad de agua para consumo humano. Empecemos a comprender de qué hablamos cuando nos referimos al agua…
El agua dulce es un recurso finito, vital para el ser humano y esencial para el desarrollo social y económico. Sin embargo, a pesar de su importancia evidente para la vida del hombre, recién en las últimas décadas se empezó a tomar conciencia pública de su escasez y el riesgo cierto de una disminución global de las fuentes de agua dulce.
La superficie de agua sobre el planeta supera abundantly to the mainland and more than 70% are seas and oceans, but this wealth is relative. 97.5% of total on the planet is salt water, while only 2.5% is fresh water.
the total percentage of fresh water almost 79% are in the form of permanent ice in the polar ice caps and glaciers, therefore not available for use. Fresh water in liquid, 20% are located in inaccessible aquifers by the depth at which they are (some cases exceed 2,000 meters under sea level). Only 1% is fresh surface water easily accessible. This represents 0.025% of water on Earth.
The renewal of fresh water sources depends on the process of evaporation and precipitation. 80% of global evaporation depends on the oceans and only 20% of precipitation over land end, feeding lakes, rivers and shallow ground water, where renewal is given by injection (1). While the volume of water has not changed in the last 30 thousand years, these resources are not inexhaustible, and who have suffered a significant deterioration in quality due to population growth and related activities.
lot of water on the planet is far from the cities, therefore, not all water is immediately usable. In addition to the rapid population growth, water potentially available for growth of the population of the earth decreased significantly in recent years and we check to diario.Se estimated that by 2025 at least three billion people could be short water worldwide.
Mind water, we can only survive a few days without serious risks to health.
