CGM grout material how to use and what's process? - Grouting material standard

CGM grout CGM grout material manufacturer CGM grout material standard specification based processing CGM grout material construction foundation surface should be cut hair treatment. Based surface cleaning, can not have gravel, laitance, floating dust, oil and demoulding seam an agent and other sundry, 24 hours before grouting, base surface should be fully wet, 1 hour before grouting, the clear water. Second, guangzhou CGM grout material for shuttering 1, according to the grouting construction drawing template. Template used with foundation, templates, and grouting material specification template seams between water mud, adhesive tape, such as seaming, reach the level of overall template is not leaking. 2, templates, and sit around the equipment at the end of the horizontal distance should be controlled in 100 mm or so, to facilitate grouting construction. 3, templates, the top level should be above the bottom of the equipment on the surface of 50 mm. Pulp, such as in 4, the grouting should be processed in a timely manner. Three, guangzhou CGM grout material preparation 1, in general, according to the common reinforcement 13 - type The standard of 14% water mixing, pisolite rugged by September 10%, 13 - type ultrafine water 14% of the standard water mixing. 2, the mixing of high-strength non-shrink grout material can use mechanical or artificial mixing. Recommended mechanical stirring, forced mixer ensures uniform mixing fully, 3 - mixing time 5 minutes. Artificial mixing time in 5 minutes to complete. Stir the grouting material, with parking schedule, reduced its liquidity, should be finished within 40 minutes. It is strictly prohibited in the high-strength non-shrink grout material mixed with any beautiful seam an agent is applied. Four, guangzhou CGM grout material construction method 1, longer equipment or track foundation, section construction should be adopted. 2, the grouting began, must be carried out continuously, not continuous, and shorten the grouting time as much as possible. , maintenance, and five 1 after grouting, grouting material after initial set and anhui high-strength non-shrink grout material shall be immediately sealed quilt sack or rock, and moist. 2, when the winter construction, grouting materials, mixing water and curing measures should comply with the current standard of engineering construction quality acceptance of concrete structures '( GB50204） The relevant provisions. 3, 24 - after grouting 36 hours by vibration, to avoid damaging not hard grouting layer.
