The instructions on grouting material

grouting material instructions grouting instruction method grouting material instructions to guide for some buyers, grouting material is not an unfamiliar product! Although their life there is a certain distance from us, but for work in the road &bridge construction workers are familiar with; Grouting material is a new type of reinforcement materials; It is combined with special cement as the seam an agent, selected for aggregate high strength material, supplemented by high flow, micro expansion, made from materials such as anti segregation, popular is the updated version of cement, concrete, on the strength, performance and service life has the very big enhancement! With the continuous development of new building materials, traditional reinforcement material; 'Cement and concrete', already cannot satisfy the requirement of some reinforcement engineering, for example. Nuclear power equipment, fixed, road and bridge engineering of reinforcement, concrete structure reinforcement and reconstruction and old concrete structure crack control, etc. , must use grouting material for repair, repair, because each grouting material and the concrete structure is extremely high, can effective engineering renovation, repair, repair and other problems. So today let's learn how to correct the use of grouting grouting material construction technology and construction process can be easy to '+' is used to describe! Because it is a new building materials, so in the process of research and development have been considering the construction problems, can be used after site construction and water mix ( Standard consistency water added is 12% 14%) In construction have reliable quality, reduce cost, shorten the construction period and convenient use. Step one: the fundamental processing of grouting material; Please clean up the surface of the base construction, there can be no gravel, laitance, dust, oil and demoulding seam an agent and other sundry, or it will affect the grouting effect, 24 h before grouting, equipment foundation surface should be fully wet, cannot have MingShui. Step 2: determine grouting; Grouting material their performance is good, grouting methods can be divided into three kinds; 'Gravity method grouting', 'high grouting funnel method', 'method of pressure grouting, choose what kind of grouting method should make sure their project status. Step three: grouting material of mould and mixing mode branch tightly and firmly to prevent loosening, slurry performance that everyone understand better not mention, grouting material mixing ( With 5 ~ 40 ℃ advisable, water temperature and water amount to 12% 14%) Can be used, stir well. Step four: grouting and curing grouting material has the advantage that the flow performance is strong; From a side down, until the other side of the overflow; ( Without vibrating! ！ ！ ） Construction after the completion of the necessary maintenance, prevent wind, hot weather, the strength is not up to damaged, sacks and felt when maintenance is available to cover, grouting layer immediately after final set sprinkler moisture curing.
