Problems solved by technology

By adding plant fibers into foam concrete, it solves the shortcomings of wall insulation materials such as poor stability, low strength, large shrinkage, and easy water absorption.
However, the added plant fiber has not been modified, which affects the durability and mechanical properties of the insulation material. On the other hand, the interface of the plant fiber premixed into the soil is not tightly connected, and the cohesion is insufficient, which further affects the compressive strength and mechanical properties of the insulation material. Thermal insulation performance
