How much water grouting material mixing and appropriate?

grouting material construction of mixing water this step is crucial, it is the key to decide whether grouting material dense. If grouting material at the time of the mixing, mixed with gas or water, will cause the grouting material construction can appear sometimes the phenomenon such as cracks, subsidence. The points for attention during the grouting material mixing are as follows: 1, using material barrel stirring, in strict accordance with the recommended water is provided in the certificate of approval. Every time a bag ( 50 kg pack) Water consumption is 6, regulations. 5 kg, that is, water cement ratio is 13%. Under the condition of meet the requirements of fluidity, water consumption can be in 6 - 6. 5 kg range change. （ The concrete is provided in the certificate of approval shall prevail) 2, the first to pour into the prescribed dosage of water in the bucket, then about half ( 25公斤) Stir in barrels, about 10 s, then in the remaining half of material mixing together. Secondary stirring time should be controlled within the 60 s. 3, the grouting material hand electric drill with homemade blade used for mixing. Mixing, blade should move slowly up and down the barrel of surrounding, and stirring blades up may not be up to above the liquid level, prevent into the air.
