Support construction method of grouting material field correctly

Pedestal grouting material specification bearing pedestal grouting grouting material bidding material performance because the frame beam and the cement on the bridge pier bearing demand four hollow bolt deepen the fixed, fixed screw pulp demand has been deep, need fixed bolt grouting materials, grouting materials quality directly decided that the strength of the bolt is fixed, therefore needs to block experiment of material, to verify that the method 1, said support grouting material, the primary test of grouting material, viscosity, strength is called a certain amount of pedestal grouting material, according to the test basis according to take appropriate amount of grouting material. 2, the pedestal grouting material mixing will be the first step to weigh the grouting materials in mixing pot, after mixing pot ascended to the right height, while mixing usually add, guide the grouting material mixing evenly. Start the cement mortar application switch, start the experiment. 3, try to grouting material not adhesive brushing oil test, test brush oil demand, because of the grouting material bonding effect is very good, grouting material tightly and try and modulus of adhesive, forming block cannot be removed, thus needs test, test gas must be uniform, so as to avoid uneven oil test part of the adhesive. 4, try to mold the grouting grouting material slowly to participate in the test, refer to the grouting materials do not overflow. Watch for grouting material in time to smooth, do not stir, 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 curing. 6, grouting material test final set in the future, just grouting material block compression, winding resistance strength test, etc.
