泡沫水泥轻质土具有良好的流动性、水硬性、施工性和经济性，具有广阔的应用前景。对泡沫水泥轻质土材料的基本性质，一般都在500 ~ 1500kg／m3的范围内调整，其抗压强度可以在0.1的范围内调整时，其流动性指数约为180 +20mm。浸泡后，表观密度增加约8%。在实际应用中，其压缩的影响是可以忽略的，其抗剪强度约为抗压强度的1/3。
Foamed cement lightweight soil has good liquidity, water hardness, construction and economy, and has wide application prospects. The basic properties of the foam cement light soil material are generally adjusted in the range of 500 ~ 1500kg / m3, and the compressive strength can be adjusted in the range of 0.1 to 1.5MPa, and its fluidity index is about 180 + 20mm. After immersion, the apparent density increased and increased by about 8%. When applied in practice, its compression and sinkage is negligible, and its shear strength is about 1 / 3 of uniaxial compressive strength.
If the fatigue load is controlled by about 50% of the uniaxial compressive strength, the influence on the strength can be neglected. For the concrete theory of embankment design for lightweight soil with foam cement, the factors such as back soil pressure, water pressure, weight, upper load, horizontal earth pressure, buoyancy, earthquake force, impact force and other factors under different conditions should be considered. The stability analysis includes local stability analysis and overall stability analysis.
Foam light soil is a new technology engineering material, which is mainly used in subgrade filling, soft foundation treatment, bridge head treatment, highway expansion, abutment backfilling and so on. Light material is a material with low apparent density and high strength made of artificial materials. Its main feature is that the apparent density is smaller than that of the general soil, and the strength and deformation properties can reach or even exceed the good soil mass.
The advantages of lightweight partition board are: sound insulation: lightweight partition board, raw material, polystyrene particles, and their sound absorbing materials. They have good sound insulation and sound absorption properties. Fire protection: light partition wall board has excellent fire resistance. After checking by the national building material quality supervision and inspection center, the fire resistance time is 4 hours, and the flammability is up to the national A-level standard. The advantages of the earthquake: lightweight partition board with traditional brick than light more than ten times, to solve the beam, column, large deep foundation problems. The slab column connection has good seismic performance, and its aseismatic performance is as high as 8.5. It is not only suitable for low rise buildings, but also for high-rise buildings and soft geological buildings. Energy saving and environmental protection: the polystyrene particles used in the light partition board have good thermal insulation performance, can achieve the effect of heat preservation and energy saving, and can reduce the electricity cost of cold and warm gas. It is the best choice to save energy. All raw materials meet the requirements of national environmental protection. The production process is free from contamination, and there is no scrap in the installation process.
