Building technology co. , LTD will teach you the correct test pedestal grouting material

Inspection right pedestal grouting material for cement of the frame beam and piers bearing four vague requirements of bolt connection, and bolt demand is fixed, the depth of the grouting material demand to the retaining bolt and grouting material quality directly determines the strength of the bolt is fixed, therefore needs to block experiment of grouting materials, to verify the request of the fixed bolt grouting material is suitable bearing mortar, primary test of grouting material of solidification point, adhesive, compressive strength, such as winding resistance strength. Bearing grouting method 1, of the test were said to take a certain amount of pedestal grouting material, according to the test range according to take appropriate amount of grouting material. 2, mixing pedestal grouting material will be the first step in the weighing of mixing grouting materials in the pot, after mixing pot ascended to the right height, while mixing usually add, tutoring grouting material mixing evenly. A cement mortar program-controlled switches, start the experiment. 3, test for grouting material is not adhesive brushing oil test, test brush oil demand, if the test does not go, because of the grouting material bonding effect is very good, firmly and grouting material modulus of adhesive, forming block cannot be removed, thus demand test, test gas must be uniform, avoid uneven formation of grouting material and no oil added to test some glue. Four, the grouting material to test the grouting is expected to slow to participate in the test, pay attention to don't overflow grouting material. Watch for grouting material in time to smooth, don't vibrate, not to take part in too fast. 5, remove the try block grouting material for mold 1 to 3 hours in the future, grouting material initial setting in the future, take out the block, and to block water maintenance. 6, grouting material test final set in the future, just grouting material block compression, winding resistance strength test, etc.
