Foam Glass in Engineering

Dec. 02, 2019

As a Foam Glass Wholesale, share with you the application of foam glass in engineering. It is one of the important issues for the construction industry to improve the thermal insulation performance of various building envelopes while maintaining the same thickness of the surrounding walls. And reducing the average apparent density of lightweight concrete to 700-900 kg / m3 is considered to be the most effective way to improve the thermal insulation performance of the outer envelope. Foam Glass was first reported in France as a lightweight concrete aggregate. In the 1930s, foam glass produced by a French company was mainly used as lightweight aggregate for concrete due to its large pore diameter and uneven distribution. Many countries have subsequently carried out related research. The Russian company has developed granular and plate-shaped foam glass, of which granular foam glass can be used directly as lightweight concrete aggregate. There are also reports in Japan. Reinforced concrete anchors that incorporate granular foam glass aggregates have a reduced mass from 760 kg to 550 kg due to the inclusion of granular foam glass, making them easier to construct and significantly reducing transportation costs.

On the other hand, about 80% of the concrete volume is gravel aggregate. In order to obtain these materials, it may be necessary to open mountain debris, destroy vegetation, cause soil and water loss, and landslides; Location, damage to embankments and waterways, pollution of river water, and severely diverted rivers, thus losing natural landscapes such as beautiful beaches. If foam glass is used as lightweight concrete aggregate, it can not only reduce pollution, but also save resources. It is an effective way to green building materials.

In order to solve the "grey pollution" problem of concrete, many methods have been adopted. A kind of multi-porous concrete or greening concrete is now popular, and its application in Japan is relatively mature. However, cement, as a cementitious material for concrete, still needs to consume a lot of resources, energy, and cause environmental pollution. In order to further promote the harmonious development of man and nature, many scholars have begun to develop other green ecological materials. As mentioned before, the water absorption of open-cell foam glass is 50% to 70%, and some are even higher. It is precisely because of its good water absorption and water retention properties that experts from Japanese universities and others. It was considered to be applied to greening projects, and a series of experiments were carried out with success. They fixed a foam glass plate with a size of 50.0 cm × 8. 0 cm × 1.0 cm as a water retaining material on a rocky slope. This kind of board has the characteristics of light weight and excellent water retention performance. Therefore, when the slope surface dries out due to water loss, the water stored in the foam glass board can continue to supply the soil and roots. These foam glass plates are staggered to organize soil loss. We also have Cellular Glass on sale, welcome to consult.
