一、加压振动成型的依据混凝土是石子、砂、水泥、水等物质混合构成.由散乱的、颗径不等的物料做成各种几何图形的构件,成型后立即脱模,并完整而不会崩缺,这就要求混凝土具有初期强度高的性能.为此,必须施加压力与高频振动同时进行,促使静止的骨料处于运动状态;物料越挤越紧,体积越缩越小,密实度越压越实.实践证明:振动成型能取得良好的密实效果,主要是在内摩擦力消失后,靠材料的重力 First, the basis of pressurized vibration molding Concrete is a mixture of stones, sand, cement, water and other materials from scattered, ranging from the material made of a variety of geometric shapes of the components, molded immediately after the release, and complete Not collapse, which requires the initial performance of concrete with high strength.To this end, the need to exert pressure and high-frequency vibration at the same time, prompting the static aggregate in motion; more squeeze the more tight the material, the smaller the smaller the volume, The more dense the more solid density. Practice has proved that: vibration molding can achieve good compactness, mainly in the disappearance of friction, the material by gravity
