Tongling, Weifang grouting material - fresh grout characteristics 
 Although fresh grouting material is only one filter state, it should be noted that given with the Peter grouting material, the density of its strength is very significant. Thus, the consistency of the mixture must make the grouting material, the the Tongling grouting material can easily hand side of transportation, placement and correction, without occurrence of segregation, it is very important. Significantly to discuss several advantages of the fresh grout material will help to change goals. 
 The quality of mixing water 
 Main effects of mixing of water in the material quality of the grouting material strength discussed later, but the quality of the water, there are other important effects: impurities in the water may affect the cement condensation, adversely affect the strength of the grouting material or in the surface-initiated blotches, or it may cause corrosion of the reinforcement. Therefore, you should consider the applicability of the mixing water and conservation purposes. Mixing water quality and erosion of water must be clearly hardened grouting material, the Tongling grouting material, the damage zone of Weifang grouting material separate. In fact, some have an adverse effect of water hardening grouting material used for mixing is harmless or even beneficial. 
 The mixing water should not contain too much organic or inorganic constituents. However, there is no clear which standard provides the quality of mixing water, in part because of the harmful ingredients in the number of boundaries is uncertain, but mainly because of this unnecessary restriction may lead to economic losses. 
 In many standards, the quality of water available provision Overview: water should be potable. This water rarely contain more than 2000ppm soluble inorganic solids, usually requiring less than 1000ppm. Number of 0.5 water-cement ratio, a content of solid 0.05% of the cement quality and less impact of the general solid. 
 Although the available reference to the water are generally safe, but there are some exceptions; For example, in some arid regions, the local drinking water, salt, and may contain excessive levels of chloride. Moreover, some natural mineral water contains excessive amount of alkali carbonate and bicarbonate, which may lead to alkali - silica reaction. 
 On the contrary, some can not refer to water can often be safe for the preparation of the grouting material. Typically, water, PH value 6.0-8.0, or 9.0, the taste is not salty, available to use; black or smell does not necessarily imply the existence of hazardous substances. The simple test the applicability of this water is in contrast to the setting time of cement and mortar cube strength of the water with known suspicious "quality" water or distilled water; is not much difference in the nature of the distilled water with ordinary water. Usually allows the intensity fluctuations of about 10%, it is recommended to carry out the experiment did not use records indicate that the dissolved solids of more than 2000ppm, or re-carbonated alkali and bicarbonate content of more than 1000ppm. If there is a rare solid, it proposes to carry out the experiment.
