Lightweight foam concrete This is a lightweight vita foam concrete technology, capable of soundproofing, insulation and moisture protection, the proportion is only 1/10 with concrete thuong.Vat this material may apply to the construction with soft soil, buildings and shock waves, road construction, underground pipeline protective coating ...
Using lightweight foam concrete is cement material containing stable gas cells. The gas cells are uniformly distributed in the concrete structure, acting as a form of aggregate. Lightweight cellular vita foam concrete mixture is made up of cement, water and foaming additives, plastics additives, mineral additives. Lightweight foam concrete as perfect can manually compacted, vita foam compacting them, without vibration. With a slight advantage (the proportion was 230-960 kg / m3, compared with conventional concrete is 2300-2500 kg / m3), reliable, stable, easy shaping, vibration resistant, non-conductive, soundproof, Waterproof lightweight vita foam concrete technology ... foam can be applied to buildings with soft soil, buildings and shock waves ... In addition, it also is used to produce construction products as insulated roof deck, floor - sound walls, prefabricated panels in the housing system, low load floor sphere ... lightweight concrete products can completely replace the traditional building materials such as Earthenware, conventional concrete, bamboo, wood, does not reduce the area of arable land as production technology terracotta tiles, cleaning vita foam the environment due to take advantage of waste from industrial and agricultural production.
Due to production technology lightweight concrete above water highly mechanized nature should labor productivity increased 20 times compared with terracotta tiles produced by the furnace tunnel. Lightweight concrete vita foam products floating on the water to be recognized as kind of advanced construction materials, light medium, only 1/2 and 1/3 Earthenware conventional concrete, durable over time, durable vita foam as concrete Usually reliable in all weather conditions, both without polluting the environment, cheaper, matching the income of the majority of people. This product is not only suitable for works on soft ground but also very suitable to build low-rise and high-rise vita foam buildings in Vietnam.
Technology for producing lightweight concrete vita foam products floating on water brought huge economic benefits to society. Compared with tunnel brick factories and power plants are producing lightweight concrete floating in the water will reduce the 75% of funds invested in a factory, down 80% of the land for production premises and decreased 99% for producing energy.
For investors in the construction and use of lightweight concrete products floating on the water will be reduced by 30% of the total load transmitted to the foundation works to reduce costs resulted in reinforcing the foundation, save energy air conditioners for residential and industrial buildings soundproof so lightweight concrete, insulating better than earthenware bricks and conventional concrete, using lightweight concrete products will reduce construction costs from 5- 7% for the 3-5 floor and fell more than 7%, for 6 or more floors.
For building contractors using lightweight concrete alternative to terracotta tiles will fall by 70% mortar, a 150% increase in labor productivity of masons and reduce transport costs by 50% compared with terracotta tiles and shipping costs only 70% compared with conventional concrete.
This is the concrete has high bearing capacity with a compressive strength after 28 days from 10-19 MPa, from 1200kg to 1600Kg weight on 1m3. (Concrete vita foam compressive vita foam strength and weight 9MPa ~ 2500Kg / m3)
Lightweight concrete, medium strength with compressive strength after 28 days from 4-8 MPa, weighing from 600 - 1000kg on 1m3. Prices in-situ concrete Polystyrol about 1.850.000d / m2 (excluding VAT).
This type of light concrete with impaired strength, often used for non-load-bearing structures or against heat. Compressive strength after 28 days from 2-4 MPa, weighing 600-1000 kg on 1m3. Foam concrete vita foam spot price is 1,500,000 / m3 (excluding VAT).
