Grouting material applied to beams, plates, columns, walls and general structures of reinforced concrete, equipment foundation secondary grouting, anchor bolts, rail clips grouting, short construction time job. Grout and concrete can be applied to equipment installed, but can only be used in the concrete foundation of a watering device, not for the second installation, because the second installation of a concrete foundation should be cemented, will shrink after concreting, resulting Some hairline cracks, though not visible for some time after the watering, but after long-term use in production facilities will produce concrete foundation fatigue, will work with a foundation broke away to form the basis of an independent device, thus affecting. Grout used for secondary grouting equipment, and cemented a firm foundation will, in the future will not shrink, early and final strength than concrete, is absolutely first installation of materials and equipment. Grout is a special kind of concrete, it does not have the ordinary concrete properties, such as gravity resistance, fast hard, no shrinkage, micro-expansion,
