The initial applications of foamed concrete primarily focused on energy-saving insulation projects for building roofs and floors. However, as the recognition of its excellent properties in other fields gradually increases, its application range is rapidly expanding, with its usage in national municipal roads, underground structures, port water conservancy, mine backfilling, and other engineering projects rising annually.
New Road Construction Projects
Foamed concrete is mainly used in new road construction projects for soft soil embankments, bridgehead embankments, and backfilling behind abutments. Utilizing the lightweight characteristics of foamed concrete, constructing embankments in deep soft soil areas can effectively reduce the additional stress on the foundation and decrease roadbed settlement, keeping it within allowable limits. When used in bridgehead embankments, it can reduce the settlement difference between the bridge and the bridgehead roadbed, providing more comfortable driving conditions. In backfilling behind retaining walls, the lightweight and self-standing properties of OREWORLD foamed concrete can reduce the lateral pressure on the retaining wall, thereby reducing the wall's size and the bearing capacity requirements of the foundation.
Road Reconstruction and Expansion Projects
Foamed concrete is generally used in road reconstruction and expansion projects to widen the roadbed of high-grade roads in soft soil areas. By utilizing the lightweight properties of foamed concrete, the settlement difference between the new and old roadbed can be minimized.
Road Maintenance Projects
In road maintenance projects, due to its lightweight, fluidity, durability, and ease of construction, lightweight foamed concrete can be used for embankment slip treatment, bridgehead bump treatment, treatment of voids under foundations, treatment of culvert foundation defects, and backfilling of abandoned pipelines.
In urban underground engineering, the lightweight properties of OREWORLD foamed concrete can act as a foundation compensator, reducing the additional stress on underground structures and ensuring the safety of the project structure. For example, in underground tunnel engineering, the structural design requires the cover soil load to be within the structural capacity. If the actual cover soil load exceeds the structural capacity, the overlying soil must be unloaded. Using cast-in-place foamed concrete for replacement is much simpler and more convenient than reinforcing the underground tunnel structure again, and it is cost-effective, offering significant technical and economic advantages.
As one of leading CSA cement suppliers, we suggest using OREWORLD' foamed concrete as a retaining wall material for port gravity-type docks can meet the slip stability requirements of the foundation surface and the overturning stability requirements of the wall front toe. Additionally, foamed concrete retaining wall foundation stress is smaller, making it more applicable for foundations with lower bearing capacity and for larger retaining wall sizes.
In civil engineering, for some narrow underground spaces, such as gaps around building foundation pits and underground pipeline projects, where human and mechanical operations are impossible or the operation space is too small to compact fill, it becomes a major engineering challenge. Utilizing cast-in-place foamed concrete, which can be pumped through hoses and occupies very little space at the pouring site, has high fluidity during pouring, can solidify after pouring, and does not require mechanical compaction or vibration, can achieve simple construction while compact filling these special voids. This provides a novel technical solution for solving the challenge of void filling.
